Background: Aneurysmal subarachnoid hemorrhage is an emergency that can lead to a high mortality rate and many severe complications. It is critical to make a rapid radiological evaluation of ruptured intracranial aneurysms (RIAs) to determine the appropriate surgical treatment.

Aim: To assess the reliability of computed tomography angiography (CTA) in assessing different features of ruptured intracranial aneurysm and its impact on patient management.

Methods: The final cohort of this study consisted of 146 patients with RIAs (75 male and 71 female) who underwent cerebral CTA. Their age ranged from 25 to 80, and the mean age ± SD was 57 ± 8.95 years. Two readers were asked to assess different features related to the aneurysm and perianeurysmal environment. Inter-observer agreement was measured using kappa statistics. Imaging data extracted from non-contrast computed tomography and CTA were considered to categorize the study population into two groups according to the recommended therapeutic approach.

Results: The inter-observer agreement of both reviewers was excellent for the detection of aneurysms (K = 0.95, P = 0.001), aneurysm location (K = 0.98, P = 0.001), and (K = 0.98, P = 0.001), morphology (K = 0.92, P = 0.001) and margins (K = 0.95, P = 0.001). There was an excellent interobserver agreement for the measurement of aneurysm size (K = 0.89, P = 0.001), neck (K = 0.85, P = 0.001), and dome-to-neck ratio (K = 0.98, P = 0.001). There was an excellent inter-observer agreement for the detection of other aneurysm-related features such as thrombosis (K = 0.82, P = 0.001), calcification (K = 1.0, P = 0.001), bony landmark (K = 0.89, P = 0.001) and branch incorporation (K = 0.91, P = 0.001) as well as perianeurysmal findings including vasospasm (K = 0.91, P = 0.001), perianeurysmal cyst (K = 1.0, P = 0.001) and associated vascular lesions (K = 0.83, P = 0.001). Based on imaging features, 87 patients were recommended to have endovascular treatment, while surgery was recommended in 59 patients. 71.2% of the study population underwent the recommended therapy.

Conclusion: CTA is a reproducible promising diagnostic imaging modality for detecting and characterizing cerebral aneurysms.

背景:动脉瘤性蛛网膜下腔出血是一种死亡率高、并发症多的急症。对颅内动脉瘤破裂(RIAs)进行快速放射学评估以确定适当的手术治疗是至关重要的。目的:评价ct血管造影(CTA)对颅内动脉瘤破裂不同特征评估的可靠性及其对患者治疗的影响。方法:本研究的最终队列包括146例RIAs患者(男性75例,女性71例),他们接受了脑部CTA。年龄25 ~ 80岁,平均年龄±SD为57±8.95岁。两位读者被要求评估与动脉瘤和动脉瘤周围环境相关的不同特征。使用kappa统计来测量观察者间的一致性。从非对比计算机断层扫描和CTA中提取的成像数据被认为是根据推荐的治疗方法将研究人群分为两组。结果:在动脉瘤的检测(K = 0.95, P = 0.001)、动脉瘤的位置(K = 0.98, P = 0.001)、形态(K = 0.92, P = 0.001)和边缘(K = 0.95, P = 0.001)方面,两位评论者的观察者间一致性非常好。在动脉瘤大小(K = 0.89, P = 0.001)、颈部(K = 0.85, P = 0.001)和颈圆比(K = 0.98, P = 0.001)的测量上,观察者之间有很好的一致性。有一个很好的inter-observer协议等其他aneurysm-related特性的检测血栓形成(K = 0.82, P = 0.001),钙化(K = 1.0, P = 0.001),骨地标(K = 0.89, P = 0.001)和分支公司(K = 0.91, P = 0.001)以及perianeurysmal发现包括血管痉挛(K = 0.91, P = 0.001), perianeurysmal囊肿(K = 1.0, P = 0.001)和相关血管病变(K = 0.83, P = 0.001)。根据影像学特点,87例患者建议行血管内治疗,59例患者建议行手术治疗。71.2%的研究人群接受了推荐的治疗。结论:CTA是一种可重复的、有前景的脑动脉瘤诊断成像方式。

Background: The course and variations of thyroid arteries must be understood by surgeons to prevent bleeding during operative procedures of the thyroid gland. There is limited scientific literature regarding the radiological anatomy of thyroid arteries in this geographical area, the Garhwal region of Sub-Himalayan belt, which is considered to be the endemic belt of goiter. Computed tomography angiography provides a three-dimensional orientation of the vascular and surgical anatomy of the entire cervical region.

Aim: To estimate the proportion of variation in origin of thyroid arteries using Computed Tomography Angiography.

Methods: Using Computed Tomography Angiography, the presence and origin of the superior thyroid artery, inferior thyroid artery, and thyroid ima artery were observed and assessed.

Results: Out of total 210 subjects, superior thyroid artery was seen to be emerging from external carotid artery in 77.1% cases. The artery was found to be originating at the level of bifurcation of common carotid artery in 14.3% cases, whereas in 8.6% cases, it emerged as a direct branch of the common carotid artery. Similarly, the inferior thyroid artery was observed to be emerging from thyrocervical trunk, subclavian artery and vertebral artery in 95.7% cases, 3.3% and 1% cases, respectively. Thyroid ima artery was also reported in a subject, arising from the brachiocephalic trunk.

Conclusion: To avoid vascular injuries, excessive and uncontrollable bleeding, intra-operative difficulties, and post-operative issues, it is imperative for surgeons to be aware of the course and variations of thyroid arteries.

背景:外科医生必须了解甲状腺动脉的病程和变化,以防止甲状腺手术过程中的出血。关于亚喜马拉雅地区Garhwal地区甲状腺动脉放射解剖学的科学文献有限,该地区被认为是甲状腺肿的特有种带。计算机断层血管造影提供了整个颈椎区域的血管和外科解剖的三维定向。目的:利用计算机断层血管造影技术估计甲状腺动脉起源变异的比例。方法:应用计算机断层血管造影技术,观察甲状腺上动脉、甲状腺下动脉、甲状腺瘤动脉的存在及起源。结果:210例患者中,77.1%甲状腺上动脉从颈外动脉伸出。14.3%的病例起源于颈总动脉分叉水平,8.6%的病例出现为颈总动脉的直接分支。同样,甲状腺下动脉出现于甲状腺颈干、锁骨下动脉和椎动脉的比例分别为95.7%、3.3%和1%。甲状腺动脉也被报道,起源于头臂干。结论:了解甲状腺动脉的病程和变化是外科医生预防血管损伤、避免出血过多和无法控制、避免术中困难和术后问题的必要措施。

Prostate cancer (Pca; adenocarcinoma) is one of the most common cancers in adult males and one of the leading causes of death in both men and women. The diagnosis of Pca requires substantial experience, and even then the lesions can be difficult to detect. Moreover, although the diagnostic approach for this disease has improved significantly with the advent of multiparametric magnetic resonance, that technology has certain unresolved limitations. In recent years artificial intelligence (AI) has been introduced to the field of radiology, providing new software solutions for prostate diagnostics. Precise mapping of the prostate has become possible through AI and this has greatly improved the accuracy of biopsy. AI has also allowed for certain suspicious lesions to be attributed to a given group according to the Prostate Imaging-Reporting & Data System classification. Finally, AI has facilitated the combination of data obtained from clinical, laboratory (prostate-specific antigen), imaging (magnetic resonance), and biopsy examinations, and in this way new regularities can be found which at the moment remain hidden. Further evolution of AI in this field is inevitable and it is almost certain to significantly expand the efficacy, accuracy and efficiency of diagnosis and treatment of Pca.

前列腺癌;腺癌是成年男性中最常见的癌症之一,也是男性和女性死亡的主要原因之一。前列腺癌的诊断需要丰富的经验,即使这样,病变也很难发现。此外,尽管随着多参数磁共振的出现,这种疾病的诊断方法有了显著改善,但该技术仍有某些未解决的局限性。近年来,人工智能(AI)被引入放射学领域,为前列腺诊断提供了新的软件解决方案。通过人工智能,前列腺的精确定位已经成为可能,这大大提高了活检的准确性。人工智能还允许根据前列腺成像报告和数据系统分类将某些可疑病变归因于给定组。最后,人工智能促进了从临床、实验室(前列腺特异性抗原)、成像(磁共振)和活检检查中获得的数据的结合,通过这种方式可以发现目前仍然隐藏的新规律。人工智能在这一领域的进一步发展是必然的,几乎可以肯定的是,人工智能将显著提高Pca的疗效、准确性和治疗效率。

Background: Although lung volumes are usually normal in individuals with chronic thromboembolic pulmonary hypertension (CTEPH), approximately 20%-29% of patients exhibit a restrictive pattern on pulmonary function testing.

Aim: To quantify longitudinal changes in lung volume and cardiac cross-sectional area (CSA) in patients with CTEPH.

Methods: In a retrospective cohort study of patients seen in our hospital between January 2012 and December 2019, we evaluated 15 patients with CTEPH who had chest computed tomography (CT) performed at baseline and after at least 6 mo of therapy. We matched the CTEPH cohort with 45 control patients by age, sex, and observation period. CT-based lung volumes and maximum cardiac CSAs were measured and compared using the Wilcoxon signed-rank test and the Mann-Whitney u test.

Results: Total, right lung, and right lower lobe volumes were significantly reduced in the CTEPH cohort at follow-up vs baseline (total, P = 0.004; right lung, P = 0.003; right lower lobe; P = 0.01). In the CTEPH group, the reduction in lung volume and cardiac CSA was significantly greater than the corresponding changes in the control group (total, P = 0.01; right lung, P = 0.007; right lower lobe, P = 0.01; CSA, P = 0.0002). There was a negative correlation between lung volume change and cardiac CSA change in the control group but not in the CTEPH cohort.

Conclusion: After at least 6 mo of treatment, CT showed an unexpected loss of total lung volume in patients with CTEPH that may reflect continued parenchymal remodeling.

背景:虽然慢性血栓栓塞性肺动脉高压(CTEPH)患者的肺容量通常正常,但约20%-29%的患者在肺功能检测中表现出限制性模式。目的:量化CTEPH患者肺体积和心脏横截面积(CSA)的纵向变化。方法:在2012年1月至2019年12月期间在我院就诊的患者的回顾性队列研究中,我们评估了15例CTEPH患者,这些患者在基线和治疗至少6个月后进行了胸部计算机断层扫描(CT)。我们将CTEPH队列与45例对照患者按年龄、性别和观察期进行匹配。使用Wilcoxon符号秩检验和Mann-Whitney u检验测量并比较基于ct的肺体积和最大心脏csa。结果:与基线相比,随访时CTEPH队列的总肺容量、右肺容量和右下肺叶容量显著减少(总P = 0.004;右肺,P = 0.003;右下叶;P = 0.01)。CTEPH组肺体积和心脏CSA的减少量明显大于对照组(P = 0.01;右肺,P = 0.007;右下叶,P = 0.01;Csa, p = 0.0002)。对照组肺体积变化与心脏CSA变化呈负相关,而CTEPH组无此相关性。结论:在治疗至少6个月后,CT显示CTEPH患者的肺总容量意外减少,这可能反映了持续的实质重塑。

Cardioembolic stroke is a potentially devastating condition and tends to have a poor prognosis compared with other ischemic stroke subtypes. Therefore, it is important for proper therapeutic management to identify a cardiac source of embolism in stroke patients. Cardiac computed tomography (CCT) can detect the detailed visualization of various cardiac pathologies in the cardiac chambers, interatrial and interventricular septum, valves, and myocardium with few motion artifacts and few dead angles. Multiphase reconstruction images of the entire cardiac cycle make it possible to demonstrate cardiac structures in a dynamic manner. Consequently, CCT has the ability to provide high-quality information about causal heart disease in cardioembolic stroke.

心脏栓塞性卒中是一种潜在的破坏性疾病,与其他缺血性卒中亚型相比,预后往往较差。因此,确定中风患者栓塞的心脏来源对于正确的治疗管理很重要。心脏计算机断层扫描(CCT)可以检测心室、室间隔和室间隔、瓣膜和心肌中各种心脏病理的详细可视化,几乎没有运动伪影和死角。整个心动周期的多相重建图像使得能够以动态方式展示心脏结构。因此,CCT有能力提供关于心脏栓塞性中风中心脏病病因的高质量信息。此外,CCT可以同时评估阻塞性冠状动脉疾病,这可能有助于为需要紧急手术的患者制定手术计划,如心脏肿瘤或感染性心内膜炎。这篇综述将介绍CCT在缺血性中风人群中的潜在临床应用,重点是使用CCT诊断心脏栓塞源。

Background: Prominent leptomeningeal contrast enhancement (LMCE) in the brain is observed in some pediatric patients during sedation for imaging. However, based on clinical history and cerebrospinal fluid analysis, the patients are not acutely ill and do not exhibit meningeal signs. Our study determined whether sevoflurane inhalation in pediatric patients led to this pattern of 'pseudo' LMCE (pLMCE) on 3 Tesla magnetic resonance imaging (MRI).

Aim: To highlight the significance of pLMCE in pediatric patients undergoing enhanced brain MRI under sedation to avoid misinterpretation in reports.

Methods: A retrospective cross-sectional evaluation of pediatric patients between 0-8 years of age was conducted. The patients underwent enhanced brain MRI under inhaled sevoflurane. The LMCE grade was determined by two radiologists, and interobserver variability of the grade was calculated using Cohen's kappa. The LMCE grade was correlated with duration of sedation, age and weight using the Spearman rho rank correlation.

Results: A total of 63 patients were included. Fourteen (22.2%) cases showed mild LMCE, 48 (76.1%) cases showed moderate LMCE, and 1 case (1.6%) showed severe LMCE. We found substantial agreement between the two radiologists in detection of pLMCE on post-contrast T1 imaging (kappa value = 0.61; P < 0.001). Additionally, we found statistically significant inverse and moderate correlations between patient weight and age. There was no correlation between duration of sedation and pLMCE.

Conclusion: pLMCE is relatively common on post-contrast spin echo T1-weighted MRI of pediatric patients sedated by sevoflurane due to their fragile and immature vasculature. It should not be misinterpreted for meningeal pathology. Knowing pertinent clinical history of the child is an essential prerequisite to avoid radiological overcalling and the subsequent burden of additional investigations.

背景:在一些儿童患者镇静成像期间,观察到大脑中明显的软脑膜对比增强(LMCE)。然而,根据临床病史和脑脊液分析,这些患者没有急性疾病,也没有出现脑膜症状。我们的研究确定了儿童患者吸入七氟醚是否导致3特斯拉磁共振成像(MRI)上的这种“伪”LMCE(pLMCE)模式。目的:强调pLMCE在儿童患者在镇静状态下接受增强脑MRI检查中的意义,以避免报告中的误解。方法:对0-8岁的儿科患者进行回顾性横断面评估。患者在吸入七氟醚的情况下接受了增强的脑部MRI检查。LMCE等级由两名放射科医生确定,并使用Cohen’s kappa计算等级的观察者间变异性。LMCE等级与镇静持续时间、年龄和体重使用Spearman rho秩相关。结果:共纳入63例患者。14例(22.2%)表现为轻度LMCE,48例(76.1%)表现为中度LMCE,1例(1.6%)表现为重度LMCE。我们发现两位放射科医生在对比后T1成像中检测pLMCE方面基本一致(kappa值=0.61;P<0.001)。此外,我们发现患者体重和年龄之间存在统计学上显著的负相关和中度相关性。镇静持续时间与pLMCE之间没有相关性。结论:pLMCE在七氟烷镇静儿童患者的对比后自旋回波T1加权MRI上相对常见,因为他们的血管系统脆弱且不成熟。不应将其误解为脑膜病理。了解儿童的相关临床病史是避免放射学过度呼叫和随后额外调查负担的重要先决条件。

Background: The data obtained on the anatomical knowledge of the tracheobronchial system can be used for diagnosis, treatment and interventional interventions in areas such as anesthesia, thoracic surgery, pulmonary physiology.

Aim: To determine the tracheobronchial branching angles in pediatric and adult populations by using the multislice computed tomography (CT) and minimum intensity projection (MinIP) technique, which is a non-invasive method.

Methods: Our study was carried out retrospectively. Patients who underwent contrast and non-contrast CT examination, whose anatomically and pathophysiologically good tracheobronchial system and lung parenchyma images were obtained, were included in the study. Measurements were made in the coronal plane of the lung parenchyma. In the coronal plane, right main bronchus-left main bronchus angle, right upper lobe bronchus-intermedius bronchus angle, right middle lobe bronchus-right lower lobe bronchus angle, left upper lobe bronchus-left lower lobe bronchus angle were measured.

Results: The study population consisted of 1511 patients, 753 pediatric (mean age: 13.4 ± 4.3; range: 1-18 years) and 758 adults (mean age: 54.3 ± 17.3; range: 19-94 years). In our study, tracheal bifurcation angle was found to be 73.3° ± 13.7° (59.6°-87°) in the whole population. In the pediatric group, the right-left main coronal level was found to be higher in boys compared to girls (74.6° ± 12.9° vs 71.2° ± 13.9°, P = 0.001). In the adult group, the right-left main coronal level was found to be lower in males compared to females (71.9° ± 12.9° vs 75.8° ± 14.7°, P < 0.001).

Conclusions: Our study, with the number of 1511 patients, is the first study in the literature with the largest number of patient populations including pediatric and adult demographic data, measuring the angle values of the tracheobronchial system using multislice CT and MinIP technique. Study data will not only be a guide during invasive procedures, but it can also guide studies to be done with imaging methods.

背景:获得的气管支气管系统解剖知识的数据可用于麻醉、胸外科、肺生理学等领域的诊断、治疗和介入干预。目的:应用多层计算机断层扫描(CT)和最小强度投影(MinIP)技术,这是一种非侵入性方法,确定儿童和成人人群的气管支气管分支角度。方法:我们的研究是回顾性的。接受对比和非对比CT检查的患者,其解剖和病理生理良好的气管支气管系统和肺实质图像均被纳入研究。测量是在肺实质的冠状面上进行的。冠状面测量右主支气管左主支气管角、右上叶支气管中间支气管角、右中叶支气管右下叶支气管角、左上叶支气管左下叶支气管角度。结果:研究人群包括1511名患者,753名儿科患者(平均年龄:13.4±4.3;范围:1-18岁)和758名成人患者(平均岁:54.3±17.3;范围:19-94岁)。在我们的研究中,整个人群的气管分叉角为73.3°±13.7°(59.6°-87°)。在儿童组中,男孩的左右主冠状面水平高于女孩(74.6°±12.9°vs 71.2°±13.9°,P=0.001)。在成年组中,男性的左右主冠面水平低于女性(71.9°±12.90°vs 75.8°±14.7°,P<0.001)。结论:我们的研究共有1511名患者,是文献中第一项拥有最多患者群体的研究,包括儿科和成人人口统计数据,使用多层CT和MinIP技术测量气管支气管系统的角度值。研究数据不仅可以指导侵入性手术,还可以指导使用成像方法进行的研究。

The goal of parathyroid imaging in hyperparathyroidism is not diagnosis, rather it is the localization of the cause of hyperparathyroidism for planning the best therapeutic approach. Hence, the role of imaging to accurately and precisely localize the abnormal parathyroid tissue is more important than ever to facilitate minimally invasive parathyroidectomy over bilateral neck exploration. The common causes include solitary parathyroid adenoma, multiple parathyroid adenomas, parathyroid hyperplasia and parathyroid carcinoma. It is highly imperative for the radiologist to be cautious of the mimics of parathyroid lesions like thyroid nodules and lymph nodes and be able to differentiate them on imaging. The various imaging modalities available include high resolution ultrasound of the neck, nuclear imaging studies, four-dimensional computed tomography (4D CT) and magnetic resonance imaging. Contrast enhanced ultrasound is a novel technique which has been recently added to the armamentarium to differentiate between parathyroid adenomas and its mimics. Through this review article we wish to review the imaging features of parathyroid lesions on various imaging modalities and present an algorithm to guide their radiological differentiation from mimics.

甲状旁腺成像在甲状旁腺功能亢进中的目的不是诊断,而是定位甲状旁腺功能亢进的原因,以便制定最佳的治疗方案。因此,影像学准确定位异常甲状旁腺组织的作用比以往任何时候都更重要,以促进双侧颈部微创甲状旁腺切除术。常见病因包括单发甲状旁腺瘤、多发甲状旁腺瘤、甲状旁腺增生和甲状旁腺癌。对于放射科医生来说,警惕类似甲状旁腺病变的甲状腺结节和淋巴结,并能够在影像学上区分它们是非常必要的。各种可用的成像方式包括高分辨率颈部超声,核成像研究,四维计算机断层扫描(4D CT)和磁共振成像。对比增强超声是一种新技术,最近被加入到鉴别甲状旁腺瘤及其模拟。通过这篇综述文章,我们希望回顾甲状旁腺病变在各种成像方式上的成像特征,并提出一种算法来指导其与模拟的放射学鉴别。

Background: Acute fibroid complications are rare. However, failure to recognize and treat acute complications expeditiously when they occur can lead to catastrophic, even deadly, complications. Pyomyoma is a rare but potentially fatal condition resulting from infarction and infection of a fibroid through bacterial seeding and direct, hematogenous, or lymphatic dissemination. Even though the diagnosis is established through clinical and laboratory findings, imaging is an important complementary method to support the suspected diagnosis.

Case summary: Herein, we report a case of a pyomyoma in a nulliparous woman previously diagnosed with uterine leiomyomatosis according to ultrasound findings. The patient had previously attended the emergency room due to hypogastric pain unresponsive to analgesics. After a week of persistent pain, she developed sepsis without any identifiable foci. Magnetic resonance imaging revealed findings compatible with uterine myomatosis with red degeneration, and a possible diagnosis of a pyomyoma was made according to the imaging findings along with the patient's clinical features. We decided to perform myomectomy (which is an infrequently performed surgical treatment due to the procedure's intrinsic implications) due to the patient's desire to preserve fertility. Histopathologic results revealed a uterine leiomyoma with coagulative and liquefactive necrosis, while the tissue culture showed gram-negative cocci bacteria, which were successfully treated using antibiotic therapy. The patient's health status improved after several days.

Conclusion: The main diagnostic tools to evaluate pyomyomas are the clinical and laboratory findings as well as tissue cultures. Nonetheless, magnetic resonance imaging can help to corroborate these findings as well as to better characterize myomas with its different complications.

背景:急性肌瘤并发症是罕见的。然而,如果不能在急性并发症发生时迅速识别和治疗,可能会导致灾难性甚至致命的并发症。脓肌瘤是一种罕见但潜在致命的疾病,由肌瘤梗死和感染引起,通过细菌播种和直接、血液或淋巴传播。尽管诊断是通过临床和实验室结果建立的,但影像学是支持疑似诊断的重要补充方法。病例总结:在此,我们报告一例子宫肌瘤,在未生育妇女以前诊断为子宫平滑肌瘤病根据超声检查。患者曾因胃下疼痛对镇痛药无反应而进过急诊室。持续疼痛一周后,她发展为败血症,没有任何可识别的病灶。磁共振成像显示符合子宫肌瘤病伴红色变性,根据影像学表现及患者临床特征,诊断为子宫肌瘤。由于患者希望保留生育能力,我们决定进行子宫肌瘤切除术(由于手术的内在含义,这是一种很少进行的手术治疗)。组织病理学结果显示子宫平滑肌瘤伴凝固性和液化性坏死,组织培养显示革兰氏阴性球菌,经抗生素治疗成功。几天后病人的健康状况有所改善。结论:评价子宫肌瘤的主要诊断手段是临床和实验室检查以及组织培养。尽管如此,磁共振成像可以帮助证实这些发现,并更好地表征肌瘤及其不同的并发症。
