Background: Profound sensorineural hearing loss (SNHL) may be the result of major inner ear structural malformations, and cochlear implantation remains the only viable treatment option. High-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) are indispensable for optimum preoperative implant workup and thus play a vital role in patient selection, pre-implantation counseling, and surgical management. Aim and Objectives: The aim of this study is to evaluate patients with profound SNHL for cochlear implantation preoperatively on both HRCT and MRI and to compare imaging findings in both modalities. Materials and Methods: This longitudinal prospective study was conducted in the Department of Radiology of a tertiary care-based hospital in North India. A total of 45 patients (90 temporal bones) with clinically diagnosed bilateral profound SNHL were included in the study. Patients with a previous history of temporal bone injury were excluded from the study. All cases were evaluated on both 128 slice Philips computed tomography (CT) machine and 1.5 Tesla Siemens Magnetom MRI scanner. Each temporal bone was systematically analyzed for anatomical and structural abnormalities. Results: Both high-resolution CT and MRI played vital roles in the workup of patients with profound SNHL for cochlear implantation and allowed accurate assessment of critical inner ear abnormalities. Cochlear malformations (30%) were responsible for the majority of structural abnormalities in this study with Type II incomplete partition (8.9%) being the most common. Cochlear nerve deficiency was seen in 20 cases (22.2%) and was diagnosed only on MRI. Similarly, early fibrosis and abnormal signal intensity were also detected only on MRI, which were missed on CT. Conclusions: Both high-resolution CT and high magnet MRI complement each other and reduce the chances of missing critical findings, which are crucial for surgical management and planning. Thus, it is advisable to perform dual imaging with both modalities wherever and whenever possible, to offer maximum information to treating surgeon preoperatively.
背景:重度感音神经性听力损失(SNHL)可能是内耳结构畸形的结果,人工耳蜗植入仍然是唯一可行的治疗选择。高分辨率计算机断层扫描(HRCT)和磁共振成像(MRI)对于最佳的术前植入工作是必不可少的,因此在患者选择,植入前咨询和手术管理中起着至关重要的作用。目的和目的:本研究的目的是评估深度SNHL患者术前人工耳蜗植入的HRCT和MRI,并比较两种方式的影像学结果。材料和方法:这项纵向前瞻性研究是在印度北部一家三级医院的放射科进行的。本研究共纳入45例临床诊断为双侧深部SNHL的患者(90块颞骨)。既往有颞骨损伤史的患者被排除在研究之外。所有病例均在128层飞利浦计算机断层扫描(CT)和1.5特斯拉西门子磁通MRI扫描仪上进行评估。系统分析各颞骨解剖和结构异常。结果:高分辨率CT和MRI在深度SNHL患者的人工耳蜗植入检查中发挥了至关重要的作用,可以准确评估内耳关键异常。耳蜗畸形(30%)是本研究中耳蜗结构异常的主要原因,其中II型不完全分割(8.9%)最为常见。耳蜗神经缺损20例(22.2%),仅MRI诊断。同样,早期纤维化和异常信号强度也仅在MRI上检测到,而在CT上未被发现。结论:高分辨率CT和高磁共振成像相辅相成,减少了遗漏关键表现的机会,这对手术管理和计划至关重要。因此,无论何时何地,只要有可能,建议采用两种方式进行双重成像,以便为术前治疗外科医生提供最大限度的信息。

Central neurocytomas (CNs) are rare benign neuroepithelial neoplasms occurring in young- and middle-aged adults. They most commonly arise within the body of the lateral ventricle, adjacent to the septum pellucidum and foramen of Monro. Patients may be asymptomatic or may present with headache and signs of raised intracranial pressure due to hydrocephalus. Preoperative diagnosis of CN by neuroimaging, electron microscopy, and immunohistochemical methods helps in planning therapy. This case describes CN in a 42-year-old female with signs and symptoms of raised intracranial pressure, neuroimaging (magnetic resonance imaging) findings, and the management.
中枢神经细胞瘤(CNs)是一种罕见的良性神经上皮肿瘤,常见于中青年。它们最常出现在侧脑室体内,靠近透明隔和门罗孔。患者可能无症状,也可能出现头痛和脑积水引起的颅内压升高的迹象。术前应用神经影像学、电镜和免疫组织化学方法诊断CN有助于制定治疗方案。本病例描述了一名42岁女性CN,其体征和症状为颅内压升高,神经影像学(磁共振成像)发现和处理。

Background: Ultrasound (US) is the first choice of imaging in neonates presenting with persistent jaundice to exclude surgically correctable causes and differentiate obstructive from nonobstructive causes. Previous studies on normal dimensions of gallbladder (GB) and common bile duct (CBD) recruited adults and children spread across a wide age group. Aims: This study aimed to determine GB and CBD normal dimensions in a large homogeneous neonatal population as well as guide decision regarding pre-US fasting in neonates who require GB evaluation. Materials and Methods: Five hundred and twenty-eight healthy newborns were recruited between May 2009 and May 2011. The widest intraluminal anterior-posterior diameters of GB and CBD were measured. Neonatal age in days, sex, birth weight, weight and height, gestational age at delivery, and time interval since last feed recorded. Results: The mean age was 9.56 ± 7.66 days, and 50.6% were males. The mean CBD diameter was 1.16 ± 1.61 mm while the mean GB diameter was 4.42 ± 2.16 mm. GB and CBD were clearly seen and measurable in 297 (55.8%) neonates and 237 (44.38%) neonates, respectively. There was a significant correlation between CBD diameter and GB diameter (P = 0.04) but no correlation with any demographic parameter. GB visualization was not dependent on time interval from last feed. Conclusion: Mean neonatal values for CBD and GB were established, but neonates have a wider range of GB diameters compared with older children, so GB diameter may not be a reliable parameter for neonatal GB pathologies. GB visualization was not dependent on time interval from last feed; hence, a recent feed should not delay emergency scans, especially in ill neonates
背景:超声(US)是表现为持续性黄疸的新生儿的首选影像学检查,以排除手术可纠正的病因,并区分梗阻性和非梗阻性病因。先前关于胆囊(GB)和胆总管(CBD)正常尺寸的研究招募了广泛年龄组的成人和儿童。目的:本研究旨在确定大量同质新生儿的GB和CBD正常尺寸,并指导需要GB评估的新生儿在US前禁食的决策。材料和方法:在2009年5月至2011年5月期间招募了528名健康新生儿。测量GB和CBD的最宽管腔内前后直径。新生儿年龄(以天为单位)、性别、出生体重、体重和身高、分娩时的胎龄以及自上次喂养以来的时间间隔。结果:平均年龄9.56±7.66天,男性占50.6%。平均CBD直径为1.16±1.61mm,平均GB直径为4.42±2.16mm。GB和CBD分别在297(55.8%)和237(44.38%)名新生儿中清晰可见和可测量。CBD直径和GB直径之间存在显著相关性(P=0.04),但与任何人口统计学参数无关。GB可视化不依赖于上次馈送的时间间隔。结论:CBD和GB的新生儿平均值已经确定,但与年龄较大的儿童相比,新生儿的GB直径范围更广,因此GB直径可能不是新生儿GB病理的可靠参数。GB可视化不依赖于从上次馈送起的时间间隔;因此,最近的喂食不应该延迟紧急扫描,尤其是对生病的新生儿

Introduction: Birth asphyxia causes significant neurologic injury and neurodevelopmental delay in children. Cranial ultrasound (CUS) can be used for the diagnosis, early intervention, and prognostication of birth asphyxia. We determined the CUS findings among term neonates with clinical birth asphyxia and correlated sonographic findings with the modified Sarnat clinical grade. Materials and Methods: We conducted a prospective cross-sectional analytical study in Kenyatta National Hospital New Born Unit (KNH NBU) between June 2018 and October 2018. Term babies, older than 24 h with clinical birth asphyxia, were recruited and CUS was performed. Statistical analysis was done using proportions, means, and frequencies. Chi-square tests were used to assess correlation between imaging findings and the clinical Sarnat grading of asphyxia. Results: Periventricular deep white matter echogenicity and thalamus and/or basal ganglia deep gray matter was reported in 56.4% and 31.1%, respectively. Only 4.4% had cortical gray matter. Normal CUS findings were reported in 40.0% of the neonates. Prolonged labor and meconium-stained liquor were the predominant risk factors for perinatal asphyxia, seen in 58% of the neonates. Prolonged labor was independently reported in 43% of the neonates. Moderate and severe Sarnat grades correlated with abnormal sonographic changes of hypoxic ischemic encephalopathy (HIE) (Grades 2–8) (P = 0.038). There was a trend toward HIE severity with worsening Sarnat stages (trend test P= 0.039). Abnormal resistive indices (<0.5 and >0.8) were strongly associated with the presence of HIE brain changes (P = 0.003). Conclusion: The correlation between birth asphyxia severity and CUS was more robust in Doppler evaluation of the deep cerebral arteries.
引言:出生窒息会导致儿童严重的神经损伤和神经发育迟缓。颅内超声(CUS)可用于新生儿窒息的诊断、早期干预和预后判断。我们确定了临床出生窒息的足月新生儿的CUS检查结果,并将超声检查结果与改良的Sarnat临床分级相关联。材料和方法:我们于2018年6月至2018年10月在肯雅塔国立医院新生儿病房(KNH NBU)进行了一项前瞻性横断面分析研究。招募24小时以上临床出生窒息的足月婴儿,并进行CUS。使用比例、平均值和频率进行统计分析。卡方检验用于评估影像学表现与窒息的临床Sarnat分级之间的相关性。结果:室周深部白质回声、丘脑和/或基底节深部灰质的报告率分别为56.4%和31.1%。皮质灰质仅占4.4%。40.0%的新生儿CUS表现正常。分娩时间过长和胎粪污染液是围产期窒息的主要危险因素,58%的新生儿出现这种情况。据独立报道,43%的新生儿产程延长。中度和重度Sarnat分级与缺氧缺血性脑病(HIE)的异常声像图变化相关(2-8级)(P=0.038)。随着Sarnat分期的恶化,HIE的严重程度有增加的趋势(趋势检验P=0.039)。异常阻力指数(0.8)与HIE脑变化的存在密切相关(P=0.003)严重程度和CUS在脑深动脉的多普勒评估中更为稳健。

Background: Public–private partnership (PPP) has become a popular model used by public sector organizations that are usually under-funded by their respective governments to render services in fulfillment of their egalitarian responsibilities and goals. Lately, the health sector has been a recipient of such initiatives and the trend is growing. However, the successful delivery of services to patients is sometimes hampered because of difficulties encountered in both the development and interpretation of clauses contained in agreements including Memoranda of Understanding between the parties. The anticipated outcomes and impact often remain elusive due to the tensions encountered during implementation. Aim and Objective: The aim of this study was to determine the current operational status as well as explore potential benefits and challenges of the use of the PPP model in radiology departments of selected teaching hospitals within three South-Western States of Nigeria (Lagos, Ogun, and Oyo). It is hoped that the study findings would provide useful data needed for improvement of the PPP model as it is being currently practiced. Materials and Methods: This was a qualitative study in which 138 closed- and open-ended questionnaires were administered to all cadres of staff in radiology departments of the selected hospitals teaching hospitals within three South-Western States of Nigeria (Lagos, Ogun, and Oyo). Results: There was a 100% response from the participants. The age range of the participants was 25–65 years. Study findings showed that almost all radiological equipment can be acquired through PPP. There was improved service delivery and residency training with PPP. Jurisdictional conflict was the greatest challenge. Conclusion: PPP is a viable option that should be encouraged by government for the purchase of equipment in hospitals.
背景:公私伙伴关系(PPP)已经成为公共部门组织使用的一种流行模式,这些组织通常在各自政府的资金不足的情况下提供服务,以履行其平等主义的责任和目标。最近,卫生部门已成为此类倡议的接受者,而且这种趋势正在增长。然而,由于各方之间的谅解备忘录等协议所载条款的制定和解释遇到困难,向病人成功提供服务有时受到阻碍。由于执行过程中遇到的紧张局势,预期的结果和影响往往难以捉摸。目的和目的:本研究的目的是确定目前的运营状况,并探讨在尼日利亚西南三个州(拉各斯、奥贡和奥约)选定的教学医院放射科使用PPP模式的潜在好处和挑战。希望研究结果能够为改进PPP模式提供有用的数据,因为它目前正在实践中。材料和方法:这是一项定性研究,其中向尼日利亚西南三个州(拉各斯、奥贡和奥约)选定的教学医院放射科的所有干部发放了138份封闭式和开放式问卷。结果:参与者的满意率为100%。参与者的年龄范围为25-65岁。研究结果显示,几乎所有的放射设备都可以通过PPP方式获得。PPP改善了服务提供和住院医师培训。管辖权冲突是最大的挑战。结论:PPP模式是一种可行的医院设备采购模式,应得到政府的鼓励。

Congenital absence of the left circumflex artery is a rare coronary anomaly with few reported cases in literature. These patients are usually diagnosed incidentally when they undergo either a conventional or a computed tomography (CT) coronary angiography to rule out an underlying coronary artery disease. Coronary CT angiography is a useful noninvasive imaging modality which can be used to diagnose and confirm coronary anomalies reliably. In this article, we report a case of a 55-year-old female who was incidentally found to have a congenitally absent left circumflex artery after a workup was initiated for nonspecific chest pain.
先天性左旋动脉缺失是一种罕见的冠状动脉异常,文献报道病例很少。这些患者通常在接受常规或计算机断层扫描(CT)冠状动脉造影以排除潜在的冠状动脉疾病时被偶然诊断。冠状动脉CT血管造影是一种有用的无创成像方式,可以可靠地诊断和确认冠状动脉异常。在这篇文章中,我们报告一个病例55岁的女性谁偶然发现有先天性左旋动脉缺失后,检查是非特异性胸痛开始。

Background: Measurement of optic nerve sheath diameter (ONSD) and anterior chamber depth (ACD) by ultrasound is increasingly used as a marker to detect raised intracranial pressure and other eye pathologies. Knowledge of normal ONSD and ACD in a healthy population is essential in the interpretation of pathological conditions. Aim: The study aimed at evaluating the ONSD and ACD of the eye in apparently healthy adults in Kano State. Materials and Methods: This was a prospective and cross-sectional study conducted among apparently healthy adults in Kano State from April 2019 to October 2019.

Introduction: Benign prostatic hyperplasia (BPH) is common in men over 50 years and causes lower urinary tract (LUT) symptoms. There is an emerging need to explore the value of utilizing ultrasound (US)-derived parameters of the LUT as noninvasive predictors of the degree of bladder outlet obstruction (BOO) from BPH and determine if they correlate with the symptom severity observed in these patients. This study aimed to determine the utility of US-derived parameters of the LUT (prostate volume [PV], bladder wall thickness [BWT], and postvoid residual volume [PVR]) in predicting severity of BOO and correlating them with the symptom severity scores – International Prostate Symptom Score (IPSS) and quality of life (QoL) – in patients with BPH in our practice. Methodology: We prospectively studied 100 newly diagnosed patients with symptomatic BPH who presented to the urology outpatient clinic and were referred to the radiology department for transabdominal scan of the urinary bladder and prostate. The patients' age, IPSS, and QoL and their BWT1 (full bladder), BWT2 (empty bladder), PV, and PVR were measured using transabdominal US scan. Correlation was done using Pearson's correlation coefficient, and P < 0.05 was considered statistically significant. Results: The mean age of the participants was 60 years. The mean BTW1 and BTW2 were 4.66 mm and 25.80 mm, respectively. The mean IPSS was 16, with a majority (42%) having severe symptoms. There is a negative insignificant correlation between PVR and BTW2 (r = −0.053, P = 0.603). There is a weak but statistically insignificant correlation between QoL and BWT. There is a weak but insignificant correlation between PV and IPSS (r = 0.193, P = 0.055). There is a weak but insignificant correlation between IPSS and BWT. There is a moderate and statistically significant correlation between IPSS and PVR (r = 0.350, P < 0.001). Conclusion: In our patients, we found that BWT had an insignificant correlation with QoL and a negative correlation with PVR, respectively. We could show, however, that in them, PVR and IPSS were significantly correlated.
简介:良性前列腺增生(BPH)常见于50岁以上男性,可引起下尿路(LUT)症状。目前需要探索利用超声(US)衍生的LUT参数作为BPH引起的膀胱出口梗阻(BOO)程度的无创预测指标的价值,并确定它们是否与这些患者观察到的症状严重程度相关。本研究旨在确定美国衍生的LUT参数(前列腺体积[PV],膀胱壁厚度[BWT]和膀胱后残留体积[PVR])在预测BOO严重程度中的效用,并将它们与我们实践中BPH患者的症状严重程度评分-国际前列腺症状评分(IPSS)和生活质量(QoL)相关联。方法:我们前瞻性研究了100例新诊断的有症状的前列腺增生患者,这些患者来到泌尿科门诊,并被转介到放射科进行膀胱和前列腺经腹扫描。采用经腹超声扫描测量患者年龄、IPSS、生活质量及BWT1(满膀胱)、BWT2(空膀胱)、PV、PVR。采用Pearson相关系数进行相关分析,P < 0.05为差异有统计学意义。结果:参与者平均年龄60岁。平均BTW1和BTW2分别为4.66 mm和25.80 mm。平均IPSS为16,大多数(42%)有严重症状。PVR与BTW2呈负不显著相关(r = - 0.053, P = 0.603)。QoL与BWT之间存在微弱但统计学上不显著的相关性。PV与IPSS的相关性不显著(r = 0.193, P = 0.055)。IPSS与BWT之间存在微弱但不显著的相关性。IPSS与PVR有中度且有统计学意义的相关性(r = 0.350, P < 0.001)。结论:在我们的患者中,我们发现BWT与QoL的相关性不显著,与PVR的相关性为负。然而,我们可以证明,在他们中,PVR和IPSS显著相关。

The novel human coronavirus (COVID-19) began in Wuhan China as an interstitial pneumonia of unidentifiable origin in December 2019 and thereafter spread its tentacles all over the world. There is a need for radiology departments in both government and private facilities to be prepared to meet this crisis. Their efforts should be geared not only toward diagnosis, but also to preventing patient-to-patient, staff-to-patient, and staff-to-staff transmission of infection by utilizing social distancing measures and personal protective equipment (PPE). Aim: To evaluate the preparedness of radiologic departments of government hospitals and private centers, by assessing the outlay of the facility and likelihood to attend to COVID patients, type of equipment in the centers, and plans in place for protection of staff and the public. Materials and Methods: The radiology departments of government and private facilities in each geopolitical zone of the country were randomly selected to discuss radiology preparedness in Nigeria using preset guidelines which were sent to radiologists at the facilities. Written informed consent was obtained from the radiologists at the participating centers. Ethical approval was also obtained from the Lagos University Teaching Hospital Health Research Ethics Committee. Results: A total of twelve centers were included in the study, comprising eight government and four private centers. All had plans in place to attend to COVID patients; majority were in the process of developing standard operating procedures (SOPs). Majority of the government facilities lacked mobile equipment and adequate PPEs, with only one computed tomography machine and no holding area in some of the facilities for symptomatic patients unlike the private facilities. They, however, had infection control teams in place. Conclusion: Private radiological centers appear better prepared and more equipped to cope with the crisis than government hospitals. Adequate PPEs, mobile equipment, and isolation rooms need to be provided for the government facilities. Radiology information systems should be installed for remote viewing. Training and retraining on COVID management and decontamination should be conducted periodically. SOPs should be drafted universally and modified for each facility.
新型人类冠状病毒(新冠肺炎)于2019年12月以不明来源的间质性肺炎在中国武汉开始传播,随后将触角伸向世界各地。政府和私人机构的放射科都需要做好应对这场危机的准备。他们的努力不仅应着眼于诊断,还应通过利用社交距离措施和个人防护装备来防止患者与患者、员工与患者以及员工与员工之间的感染传播。目的:通过评估设施支出和照顾新冠肺炎患者的可能性、中心设备类型以及保护工作人员和公众的计划,评估政府医院和私人中心放射科的准备情况。材料和方法:随机选择该国每个地缘政治区的政府和私人机构的放射科,使用预先设定的指南讨论尼日利亚的放射准备情况,并将其发送给这些机构的放射科医生。获得参与中心放射科医生的书面知情同意书。还获得了拉各斯大学教学医院健康研究伦理委员会的伦理批准。结果:共有12个中心被纳入研究,包括8个政府中心和4个私人中心。所有人都制定了照顾新冠肺炎患者的计划;大多数正在制定标准操作程序。与私人设施不同,大多数政府设施缺乏移动设备和足够的个人防护用品,只有一台计算机断层扫描机,一些设施没有为有症状的患者提供等候区。然而,他们有感染控制小组。结论:与政府医院相比,私人放射中心似乎准备得更好,设备也更齐全,能够应对危机。政府设施需要配备足够的个人防护用品、移动设备和隔离室。应安装放射信息系统以进行远程查看。应定期进行新冠肺炎管理和净化方面的培训和再培训。应普遍起草SOP,并对每个设施进行修改。

Background: Lately, there has been an increased utilization of computed tomography angiography (CTA) as the preferred first-line modality for the evaluation and diagnosis of most cerebral vascular lesions. Objective: The objective of this study was to evaluate suspected intracranial vascular cases, using CTA at a major referral tertiary hospital in South West Nigeria. Materials and Methods: This was a hospital-based retrospective study of suspected intracranial vascular cases in all ages and both sexes that had CTA from January 2011 to December 2018. Data were analyzed with IBM SPSS version 23.0, and P < 0.005 was considered statistically significant. Results: A total of 128 patients were studied, the mean age was 44.1 ± 17.7 years, and male: female ratio was 1:1.06. The leading clinical diagnoses were as follows: intracranial aneurysms (34/128), subarachnoid hemorrhage (27/128), intracranial vascular tumors (26/128), brain hemorrhage from vascular abnormality (19/128), and arteriovenous malformations (AVMs) (10/128). At CTA, 61 patients had vascular abnormalities: intracranial aneurysm was seen in 63.9% with a peak age range of 41–60 years, and the leading location of aneurysms was posterior cerebral artery (18.8%), followed by posterior communicating artery (16.7%) and the cavernous segment of the internal carotid artery (16.7%). AVMs were more common in patients aged 40 years and below (91.7%) in males (66.7%) and in the parietal lobe. Intracranial aneurysms were 3.25 times as common as brain AVMs. Conclusion: Intracranial aneurysms are the predominant vascular lesions, occurring mostly in the older age group. AVMs occurred mostly in younger people, more in males, and predominantly in the parietal lobes. The hospital incidence of aneurysms to AVMs was 3.25:1.
背景:最近,计算机断层摄影血管造影术(CTA)作为评估和诊断大多数脑血管病变的首选一线方式,得到了越来越多的应用。目的:本研究的目的是在尼日利亚西南部一家主要转诊三级医院使用CTA评估疑似颅内血管病例。材料和方法:这是一项基于医院的回顾性研究,对2011年1月至2018年12月接受CTA检查的所有年龄和性别的疑似颅内血管病例进行了回顾性研究。数据采用IBM SPSS 23.0版进行分析,P<0.005被认为具有统计学意义。结果:共研究了128名患者,平均年龄为44.1±17.7岁,男女比例为1:1.06。主要临床诊断如下:颅内动脉瘤(34/128)、蛛网膜下腔出血(27/128)、颅内血管瘤(26/128),血管异常引起的脑出血(19/128)和动静脉畸形(AVMs)(10/128)。在CTA中,61名患者出现血管异常:63.9%的患者出现颅内动脉瘤,峰值年龄范围为41-60岁,动脉瘤的主要位置是大脑后动脉(18.8%),其次是后交通动脉(16.7%)和颈内动脉海绵体段(167%)。AVMs在40岁及以下患者(91.7%)、男性(66.7%)和顶叶更常见。颅内动脉瘤的发病率是脑动静脉畸形的3.25倍。结论:颅内动脉瘤是主要的血管病变,多发生在老年组。AVMs主要发生在年轻人中,更多发生在男性中,主要发生在顶叶。动脉瘤与动静脉畸形的住院发病率为3.25:1。
