Background: Our aim was to assess the relationship between postoperative recurrent low back pain and vertebral body end-plate signal intensity changes on magnetic resonance imaging in disc herniation patients. Materials and Methods: The preoperative magnetic resonance images of 748 patients were retrospectively reviewed. End-plate changes were separated into three groups according to the Modic classification. The postoperative clinical improvement was defined according to the Kawabata criteria. The localization and type of end-plate degeneration and improvement after the operation were analyzed with Pearson's Chi-square test. Results: End-plate degeneration was found in 394 of 748 patients. Single-level and multiple-level end-plate changes were present in 70.4% and 29.6% of the patients, respectively. Type 2 (85.5%), type 1 (10.7%), and type 3 (3.8%) degenerations were encountered in order of frequency. The severities of the end-plate changes were mild, moderate, and severe in 63.2%, 32.7%, and 4.1% of the patients. Type 1 and type 2 degenerations correlated with clinical course in the postoperative period (P < 0.05). Conclusions: Type 1 and type 2 degenerative end-plate changes seen on preoperative magnetic resonance scans can influence the clinical course and be an indicator of postoperative back pain.
背景:我们的目的是评估椎间盘突出患者术后复发性腰痛与磁共振成像椎体终板信号强度变化的关系。材料与方法:回顾性分析748例患者的术前磁共振图像。根据Modic分类将终板改变分为三组。术后临床改善根据川边标准确定。采用Pearson卡方检验分析手术后终板退变的位置、类型及改善情况。结果:748例患者中394例出现终板退变。70.4%和29.6%的患者分别出现单节段和多节段终板改变。2型(85.5%)、1型(10.7%)和3型(3.8%)变性的发生频率依次为。终板改变的严重程度分别为轻度、中度和重度,分别占63.2%、32.7%和4.1%。术后1型、2型变性与临床病程相关(P < 0.05)。结论:术前磁共振扫描显示的1型和2型退变性终板改变可影响临床病程,并可作为术后背痛的指标。

Context: Pangolins are scaly ant-eating placental mammals threatened with extinction due to over-exploitation and poaching. Aggressive protection by conservationists is moderately successful due to scanty information regarding their physiology. Aims: Contrast radiography, a diagnostic technique for investigating gastrointestinal diseases may assist conservation efforts to improve the survival of these animals. Subjects and Methods: Eight rescued white-bellied pangolins of different ages, sexes, and weights were evaluated. Four live ones; with a mean weight of 1.52 ± 0.3 kg were radiographed and measurements taken by Digimizer. Four others had an opportunistic necropsy done and gross measurements of the gastrointestinal tract. Sedation with Ketamine caused uncurling, facilitated handling, and barium was administered orally. Serial dorso-ventral and lateral radiographs, physiological parameters, gastrointestinal dimensions, and contrast images were acquired. Results: The oral cavity was oval-shaped with no teeth; the long thin tongue runs beside the esophagus and contrast within the stomach 0 min postadmin lends credence to the length of the tongue just proximal to the stomach at the 8th thoracic rib. The plain radiograph revealed stones within the stomach at the 10th thoracic rib. The esophageal length, stomach length, and width radiographically, were 201.38 ± 1.70, 95.42 ± 1.9, and 53.02 ± 16.70 mm while the gross gastric length, diameter, and intestinal length were 7.1 ± 0.12, 13.3 ± 0.4, and 220.21 ± 4.03 cm, respectively. The mean contrast transit time was 1.34 ± 0.65 h-stomach, 0.48 ± 0.48 h-small intestines, and 10.00 ± 5.76 h-large intestines. Compared to mean transit times in dogs, it is longer but shorter when the transit times are compared to mean transit times in rats. Conclusion: Average transit time of the digestive tract is consistent with the reported average in dogs (3 ± 1.5 h). Implications for feeding and gut health in pangolins can assist in understanding critical care and boost conservation efforts.
背景:穿山甲是一种有鳞片、以蚂蚁为食的胎盘哺乳动物,由于过度开发和偷猎,穿山甲濒临灭绝。由于缺乏关于它们生理方面的信息,自然资源保护者的积极保护是适度成功的。目的:造影术,一种用于调查胃肠道疾病的诊断技术,可能有助于保护工作,提高这些动物的存活率。对象与方法:对8只获救的不同年龄、性别、体重的白腹穿山甲进行评价。四只活的;平均体重1.52±0.3 kg,用Digimizer照相测量。另外四人进行了机会性尸检,并对胃肠道进行了大体测量。氯胺酮镇静导致卷曲,易于处理,并口服钡。获得了一系列的背腹侧位片、生理参数、胃肠尺寸和对比图像。结果:口腔呈椭圆形,无牙;又长又细的舌头在食道旁边,在胃里的对比图显示在胃近端第8胸椎肋骨处舌头的长度。x线平片显示第十胸椎胃内结石。食管长、胃长、胃宽分别为201.38±1.70、95.42±1.9、53.02±16.70 mm,胃长、胃径、肠长分别为7.1±0.12、13.3±0.4、220.21±4.03 cm。平均造影传递时间胃为1.34±0.65 h,小肠为0.48±0.48 h,大肠为10.00±5.76 h。与狗的平均传递时间相比,它更长,但与大鼠的平均传递时间相比,它更短。结论:穿山甲消化道的平均转运时间与狗的平均(3±1.5小时)一致。对穿山甲喂养和肠道健康的影响有助于了解重症监护和促进保护工作。

Background: Hearing loss is a major problem in children because of its devastating effect on education and cognitive development. Clinicians rely on pure-tone audiometry (PTA) to determine the types and degrees of hearing loss; however, the test is subjective and cannot determine the cause of the hearing loss. Computed tomography (CT) of the temporal bone is important for evaluating hearing loss, due to its ability to identify bony ear malformations and to examine pathologies of the middle and the inner ear. The objective of this study was to determine bony labyrinthine anomalies in a group of children with profound and severe hearing loss. Materials and Methods: This was a descriptive cross-sectional study conducted among students from a school with special needs in Osogbo, Osun State, Nigeria. One hundred and twenty students with hearing loss selected by stratified systematic random sampling participated in this study. There were 66 (55%) males and 54 (45%) females. Demographic data were collected from the participants and from the school records. All the participants went through audiometry so as to determine and confirm their thresholds and a high-resolution CT scan of the temporal bone to determine bony labyrinthine abnormalities. Results: One hundred and twenty participants making 240 ears were studied, with a mean age of 12.1 ± 2.3 years. Ninety-five participants (79.2%) had prelingual hearing loss while 25 (20.8%) had acquired postlingual hearing loss. Nine participants (7.5%) had abnormalities of the bony labyrinth; seven of which had bilateral and two unilateral bony abnormalities, and thus 16 (6.7%) out of 240 ears had such abnormalities. The most common cochlear abnormality was hypoplasia 6 ears (37.5%), followed by type I incomplete cochlear partitions 3 ears (18.7%). Conclusion: This study found that the bony labyrinth was normal in 93.3% of ears, and the most common bony anomaly was cochlear hypoplasia.
背景:听力损失是儿童的主要问题,因为它对教育和认知发展具有破坏性影响。临床医生依靠纯音测听(PTA)来确定听力损失的类型和程度;然而,测试是主观的,不能确定听力损失的原因。颞骨计算机断层扫描(CT)对于评估听力损失很重要,因为它能够识别骨性耳畸形并检查中耳和内耳的病理。本研究的目的是确定骨迷路异常在一组儿童的深度和严重的听力损失。材料和方法:这是一项描述性横断面研究,在尼日利亚奥孙州奥索博一所有特殊需要的学校的学生中进行。采用分层系统随机抽样的方法,抽取120名听力损失学生参加本研究。男性66例(55%),女性54例(45%)。从参与者和学校记录中收集了人口统计数据。所有的参与者都通过听力学来确定和确认他们的阈值,并通过颞骨的高分辨率CT扫描来确定骨迷路异常。结果:研究对象120人,共240耳,平均年龄12.1±2.3岁。95名参与者(79.2%)有语前听力损失,25名参与者(20.8%)有语后听力损失。9例(7.5%)有骨迷路异常;其中双侧骨异常7例,单侧骨异常2例,共16例(6.7%)。最常见的耳蜗异常为发育不全6耳(37.5%),其次为ⅰ型耳蜗不完全分隔3耳(18.7%)。结论:93.3%耳骨迷路正常,以耳蜗发育不全为最常见的骨异常。

Background: Accurate estimation of fetal birth weight is critical in determining the delivery route and management of the neonate. Purpose of Study: The purpose is to determine the accuracy of Hadlock IV, Campbell, and Shepard's algorithm as predictors of birth weight in a cohort of fetuses of Yoruba descent. Materials and Methods: Fetal weight (FW) was estimated in a sample of 384 fetuses using Hadlock IV, Campbell, and Shepard's algorithm while actual birth weight (ABW) was measured. Receiver operating characteristic curves were plotted and used to determine the accuracy and sensitivity of each algorithm. Results: Most babies (84.6%) had normal estimated fetal weight (EFW) and ABW; mean FW = 3.2 ± 0.5 kg); 10% had low weight while 5.5% were macrosomic. While EFW correlated positively and strongly with ABW, the Hadlock IV algorithm had the strongest correlation (r = 0.978). The Hadlock IV, Campbell, and Shepard's algorithms had 92%, 72%, and 56% accuracy within the tenth centile, respectively. At 95% confidence interval, Hadlock IV was the most accurate predictor of normal birth and low birth weight (area under the curve [AUC] =0.91 and 0.94, respectively). Campbell was the most accurate predictor of macrosomia (AUC = 0.89). Conclusion: While Hadlock IV and Campbell algorithm are valid predictors, the Shepard model is a doubtful birth weight predictor among fetuses of Yoruba origin. When there is a need for absolute birth weight values, the Hadlock IV algorithm is preferred for suspected normal and low-weight babies while the Campbell model is preferred for fetuses weighing >4 kg among Yoruba fetuses.
背景:准确估计胎儿出生体重对于确定分娩路线和新生儿管理至关重要。研究目的:目的是确定Hadlock IV、Campbell和Shepard算法作为约鲁巴裔胎儿出生体重预测指标的准确性。材料和方法:使用Hadlock IV、Campbell和Shepard算法对384名胎儿样本进行胎儿体重(FW)估计,同时测量实际出生体重(ABW)。绘制了接收器工作特性曲线,并用于确定每种算法的准确性和灵敏度。结果:大多数婴儿(84.6%)具有正常的估计胎儿重量(EFW)和ABW;平均FW=3.2±0.5 kg);10%为低体重儿,5.5%为巨大儿。虽然EFW与ABW呈正相关,但Hadlock IV算法的相关性最强(r=0.978)。HadlockⅣ算法、Campbell算法和Shepard算法在十分位数内的准确率分别为92%、72%和56%。在95%置信区间下,Hadlock IV是正常出生和低出生体重的最准确预测因子(曲线下面积AUC=0.91和0.94)。Campbell是巨大儿最准确的预测因子(AUC=0.89)。结论:虽然Hadlock IV和Campbell算法是有效的预测因子,但Shepard模型在约鲁巴族胎儿中是一个值得怀疑的出生体重预测因子。当需要绝对出生体重值时,Hadlock IV算法优先用于疑似正常和低体重婴儿,而Campbell模型优先用于约鲁巴胎儿中体重>4公斤的胎儿。

Pilocytic astrocytomas (PAs) are the most common pediatric primary brain tumor. They are World Health Organization Grade 1 tumors with an excellent prognosis. In children, the cerebellum, optic nerve chiasm, and hypothalamic region are the most common locations in that order. Clinically, cranial nerve palsies, symptoms of raised intracranial pressure, and ataxia are commonly seen. We present an unusual case of PA in a 3-year-old toddler with inability to walk. High index of suspicion is required for the diagnosis of posterior fossa tumors in this age group as they can deteriorate rapidly.
毛细胞星形细胞瘤(PAs)是儿童最常见的原发性脑肿瘤。它们是世界卫生组织一级肿瘤,预后良好。在儿童中,小脑、视神经交叉和下丘脑区域是最常见的位置。临床上,脑神经麻痹、颅内压升高和共济失调是常见的症状。我们提出一个不寻常的情况下,PA在一个3岁的幼儿不能走路。后窝肿瘤的诊断需要高度的怀疑指数,因为它们可以迅速恶化。

Size and shape of sella turcica among Down syndrome individuals in a Nigerian population 尼日利亚唐氏综合症患者蝶鞍的大小和形状
Pub Date : 2022-01-01 DOI: 10.4103/wajr.wajr_29_21

Background/Aims: This study was conducted to determine the size and shape of sella turcica (ST) among Down syndrome (DS). Materials and Methods: The size of the ST was determined among 29 DS (mean age 13.76 ± 2.41 years), while the shape of the ST was among 25 DS individuals (mean of 13.84 ± 2.41 years) who met the inclusion criteria. Statistical significance of linear measurement in relation to gender was evaluated using an independent t-test, while Chi-square test was used to analyze the occurrence and significance of the shape. A statistically significant level was set at P < 0.05. Results: ST length (STL), depth (STD), and anterior–posterior diameter (STAPD) were 9.00 ± 3.23 mm, 7.61 ± 1.51 mm, and 10.45 ± 2.79 mm, respectively. Female DS had a larger value for STD and STAPD than males (P > 0.05). The pyramidal shape of the dorsum sella accounted for the largest deviation (28.3%) in shape. A change in shape of the ST tend to affect the depth (F = 1.669, P = 0.204) and diameter (F = 1.425, P = 0.263) than its effects the length. Conclusion: The depth and diameter of ST were observed to be larger than normal individuals within the same age range documented in the literature. Abnormal deviation in the shape of sell turcica may have contributed to the variation in the length, depth, and diameter. A deviation in the size and shape of ST could be considered etiological factor in the development of malocclusion among Down syndrome individuals.
背景/目的:本研究旨在确定唐氏综合征(DS)患者鞍区(ST)的大小和形状。材料和方法:在29名符合纳入标准的DS患者(平均年龄13.76±2.41岁)中确定ST段的大小,而在25名符合纳入条件的DS患者中(平均13.84±2.41年)确定ST段形状。使用独立t检验评估与性别相关的线性测量的统计显著性,而卡方检验用于分析形状的发生率和显著性。具有统计学意义的水平设定为P<0.05。结果:ST段长度(STL)、深度(STD)和前后径(STAPD)分别为9.00±3.23 mm、7.61±1.51 mm和10.45±2.79 mm。女性DS的STD和STAPD值高于男性(P>0.05)。鞍背锥体形状的形状偏差最大(28.3%)。ST形状的变化倾向于影响深度(F=1.669,P=0.204)和直径(F=1.425,P=0.263),而不是影响长度。结论:ST段的深度和直径均大于文献中记载的同年龄段的正常人。龟甲形状的异常偏差可能是造成其长度、深度和直径变化的原因之一。ST段大小和形状的偏差可能被认为是唐氏综合征患者发生错牙合的病因。

Materials and Methods: The size of the ST was determined among 29 DS (mean age 13.76 ± 2.41 years), while the shape of the ST was among 25 DS individuals (mean of 13.84 ± 2.41 years) who met the inclusion criteria. Statistical significance of linear measurement in relation to gender was evaluated using an independent t-test, while Chi-square test was used to analyze the occurrence and significance of the shape. A statistically significant level was set at P < 0.05. Results: ST length (STL), depth (STD), and anterior–posterior diameter (STAPD) were 9.00 ± 3.23 mm, 7.61 ± 1.51 mm, and 10.45 ± 2.79 mm, respectively. Female DS had a larger value for STD and STAPD than males (P > 0.05). The pyramidal shape of the dorsum sella accounted for the largest deviation (28.3%) in shape. A change in shape of the ST tend to affect the depth (F = 1.669, P = 0.204) and diameter (F = 1.425, P = 0.263) than its effects the length. Conclusion: The depth and diameter of ST were observed to be larger than normal individuals within the same age range documented in the literature. Abnormal deviation in the shape of sell turcica may have contributed to the variation in the length, depth, and diameter. A deviation in the size and shape of ST could be considered etiological factor in the development of malocclusion among Down syndrome individuals.","PeriodicalId":29875,"journal":{"name":"West African Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47910436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: Musculoskeletal infections have been emerging nowadays. Its early diagnosis is warranted as it may lead to disabling sequelae. Recently, the use of diffusion-weighted magnetic resonance imaging (DWMRI) provided additional pulse sequences enabling better diagnosis and needs to be explored for diagnosing musculoskeletal infections. Thus, we conducted this study with an aim to discuss demographic, clinical, and DWMRI findings of the spectrum of musculoskeletal infections, emphasizing the apparent diffusion coefficient (ADC) map for this domain of infections. Methods: A retrospective observational study was carried out in the department of radiodiagnosis of a tertiary care hospital. The study was performed on 50 patients who were suspected cases of musculoskeletal infections. All the patients underwent basic investigations, ultrasound, magnetic resonance imaging, and diffusion-weighted imaging with ADC mapping. The data were entered into MS EXCEL spreadsheet and analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0. Results: Maximum patients were in the age group of 11–20 years (40%) with 58% males and 42% females. Lower limb infections were common, especially the involvement of the hip joint. Pain and swelling were the most common symptoms as seen in 96% and 88% of the patients respectively. DWMRI was able to diagnose and lay down significantly different ADC values for different musculoskeletal infections. The mean ADC values were higher for acute infections and lower for chronic infections. Conclusions: DWMRI holds an important role in the investigation profile for musculoskeletal infections and must be used wherever deemed necessary to avoid unnecessary referrals and treatments.
引言:如今,肌肉骨骼感染已经出现。它的早期诊断是有必要的,因为它可能会导致致残后遗症。最近,扩散加权磁共振成像(DWMRI)的使用提供了额外的脉冲序列,能够更好地进行诊断,并且需要探索用于诊断肌肉骨骼感染。因此,我们进行这项研究的目的是讨论肌肉骨骼感染谱的人口学、临床和DWMRI结果,强调该感染领域的表观扩散系数(ADC)图。方法:在某三甲医院放射诊断科进行回顾性观察研究。这项研究对50名疑似肌肉骨骼感染的患者进行了研究。所有患者均接受了基础检查、超声、磁共振成像和ADC标测的扩散加权成像。将数据输入MS EXCEL电子表格,并使用社会科学统计软件包(SPSS)21.0版进行分析。结果:最多的患者年龄组为11–20岁(40%),其中58%为男性,42%为女性。下肢感染很常见,尤其是髋关节受累。疼痛和肿胀是最常见的症状,分别为96%和88%的患者。DWMRI能够诊断和确定不同肌肉骨骼感染的ADC值。急性感染的平均ADC值较高,慢性感染的平均值较低。结论:DWMRI在肌肉骨骼感染的调查中发挥着重要作用,必须在必要时使用,以避免不必要的转诊和治疗。

Objectives: To study congenital anomalies discovered during antenatal care in three medical imaging centers in the city of Ouagadougou. Specifically, the aim was to determine the prevalence of antenatal malformations on ultrasound, to identify the different types of malformations detected and to determine the average gestational age (GA) of discovery of CAMs in our context. Materials and Methods: This was a retrospective and prospective multicenter cross-sectional study conducted in the imaging departments of the following three health facilities: the University Hospital of Bogodogo (CHUB), the Nina Polyclinic, and the Yati Medical Clinic. The study was carried out from January 1, 2016, to October 31, 2019. It included all women who had a fetal malformation during obstetrical ultrasound performed during the study period. Results: Fetal malformations represented 1.10% of all obstetric ultrasounds performed in the three medical imaging centers in the city of Ouagadougou. The mean GA of discovery of CAMs was 27 weeks 2 days. The most common malformations were (in decreasing order) the central nervous system (67.10%), the urogenital system (18.62%), the abdomen (14.72%), the digestive system (13.85%), the skeleton (13.42%), the cardiovascular system (8.23%), and the respiratory system (5.19%). An abnormality of the amniotic fluid was associated with 35.50% of the malformations detected. Conclusion: The prevalence of congenital anomaly in our study is similar to that of other studies and obstetric ultrasound plays a key role in its early antenatal diagnosis”.

Objectives: The aim of the index study was to describe the pattern and frequency of structural brain lesions in magnetic resonance imaging (MRI) of patients with dementia. Methods: This was a retrospective, descriptive study carried out in Memfys Hospital in Enugu, South East Nigeria, to review all MRIs of patients who presented with progressive cognitive decline. Results: Out of a total of 147 (86.5%) scan reviewed, 6 (6.8%) had normal brain scan, while 95 (64.6%) had brain atrophy, followed by white matter lesions 78 (49.7%). Strokes, including lacunar stroke, were seen in 44 (29.9%). Hydrocephalus (14.3%) and brain tumors (11.6%) were the most common surgical lesion found. Patients with atrophy (P < 0.01) and white matter lesions (P < 0.01) were significantly older compared to the average age of the cohort, while patients with normal brain scans and brain tumors were younger P < 0.01 and P = 0.02, respectively. Conclusion: Brain atrophy and white matter lesions were the most common MRI findings in patients presenting with cognitive decline in Enugu, South East Nigeria. Such patients also tended to be older than those with normal brain scans or brain tumors.
目的:指标研究的目的是描述痴呆患者磁共振成像(MRI)中大脑结构损伤的模式和频率。方法:这是一项在尼日利亚东南部埃努古的Memfys医院进行的回顾性描述性研究,旨在回顾所有表现为进行性认知能力下降的患者的核磁共振成像。结果:在147例(86.5%)回顾性扫描中,6例(6.8%)脑部扫描正常,95例(64.6%)脑部萎缩,其次是白质病变78例(49.7%)。44例(29.9%)出现中风,包括腔隙性中风。脑积水(14.3%)和脑肿瘤(11.6%)是最常见的手术损伤。与队列的平均年龄相比,萎缩(P<0.01)和白质病变(P<0.01)的患者明显更老,而正常脑扫描和脑肿瘤的患者则更年轻,分别为P<0.01和P=0.02。结论:在尼日利亚东南部埃努古,脑萎缩和白质病变是认知能力下降患者最常见的MRI表现。这类患者的年龄也往往比那些正常脑部扫描或脑部肿瘤的患者大。

Background: The current imaging modality of choice in the evaluation of patients with seizures is magnetic resonance imaging (MRI). MRI with a specific seizure protocol considerably has a positive impact on patients' management. This study determined the spectrum of brain findings in children with seizures. Materials and Methods: The study subjects were 191 children aged 1–16 years who presented with seizures within January 2017–August 2021. Socio-demographics and MRI examinations were retrospectively studied. Brain MRI images of patients with their respective reports were analyzed by experienced radiologists. Data from these reports were collected and coded into Statistical Package for Social Sciences (SPSS) version-20.0 for analysis. Results: One hundred and ninety-one children were included in the study comprising 99 (51.8%) males and 92 (48.2%) females. Abnormal brain images were noted in 89 (46.6%) of the study population. The most common abnormalities were cerebral atrophy 41 (21.5%), white matter T2 Fluid-attenuated inversion recovery hyperintensities 22 (11.5%), and temporal lobe atrophy 9 (4.7%). Twenty-six (29.2%) of the children presented with multiple lesions and these were more common in children <5 years of age. Conclusion: MRI is extremely useful in the early detection and diagnosis of the causes of seizures in children in low socio-economic setting like ours. The majority of the children with brain lesions were under five years, and in a setting like ours, all efforts should be made to image them since they are sometimes denied MRI due to the relatively high cost of the procedure.
背景:目前在评估癫痫发作患者时选择的成像方式是磁共振成像(MRI)。具有特定癫痫发作方案的MRI对患者的管理有很大的积极影响。这项研究确定了癫痫发作儿童的脑部表现。材料和方法:研究对象为191名1-16岁的儿童,他们在2017年1月至2021年8月期间出现癫痫发作。对社会人口统计学和MRI检查进行了回顾性研究。由经验丰富的放射科医生分析患者的脑MRI图像及其各自的报告。收集这些报告的数据,并将其编码到社会科学统计软件包(SPSS)2.0版中进行分析。结果:191名儿童被纳入研究,其中男性99名(51.8%),女性92名(48.2%)。在89名(46.6%)研究人群中发现了异常脑图像。最常见的异常是脑萎缩41例(21.5%),白质T2液体减弱反转恢复高信号22例(11.5%),颞叶萎缩9例(4.7%)。26例(29.2%)儿童出现多发性病变,这些在5岁以下的儿童中更常见。结论:MRI在早期发现和诊断像我们这样社会经济水平低的儿童癫痫发作的原因方面非常有用。大多数患有脑损伤的儿童年龄在五岁以下,在我们这样的环境中,应该尽一切努力对他们进行成像,因为由于手术成本相对较高,他们有时会被拒绝接受核磁共振成像。
