Background: Disparities in MR access between different countries and healthcare systems are well documented. Determinants of unequal access within the same healthcare system and geographical region are poorly understood.

Objective: An analysis of public sector MR utilisation in South Africa's Western Cape province (WCP).

Methods: A retrospective study of WCP MR and population data for 2013 and 2018. MR units/106 people, studies, and studies/103 people were calculated for each year, for the whole province and the 'western' and 'eastern' referral pathways, stratified by age (0-14 years, > 14 years).

Results: Between 2013 and 2018, the WCP population increased 8% (4.63 vs 5.08 × 106 people) while MR resources were unchanged ('western' = 2 units; 'eastern' = 1), equating to decreasing access (units/106 people) for the province (0.65 vs 0.59; -9.2%), the 'western' (0.97 vs 0.9; -7.2%) and 'eastern' (0.39 vs 0.35; -10.3%) pathways. In 2013, 40% (4005/10 090) of studies were in the 'eastern' pathway serving 55% (2 066 079/4 629 051) of the population. Between 2013 and 2018 'eastern' population growth (n = 286 781) exceeded 'western' (n = 168 469) by 70% (n = 118 312). By 2018, 38% (7939/12 848) of studies were performed in the 'eastern' pathway, then serving 56% (2 849 753/5 084 301) of the population. Among 0-14-year-olds, 'western' utilisation (studies/103 people) exceeded 'eastern' by a factor of approximately 2.4 throughout. In patients > 14 years, the utilisation differential increased from 1.78 to 1.98 in the review period.

Conclusion: Ensuring equitable services on the same healthcare platform requires ongoing surveillance of resource and population distribution. MR access can serve as a proxy for equity in highly specialised services.

背景:不同国家和卫生保健系统在磁共振可及性方面的差异已有充分记录。在同一医疗保健系统和地理区域内不平等获取的决定因素了解甚少。目的:分析南非西开普省(WCP)公共部门MR的使用情况。方法:对2013年和2018年WCP MR和人群数据进行回顾性研究。每年计算全省以及“西部”和“东部”转诊途径的MR单位/106人,研究和研究/103人,按年龄(0-14岁,> 14岁)分层。结果:2013 - 2018年间,WCP人群增加了8% (4.63 vs 5.08 × 106人),而MR资源不变(“西部”= 2单位;“东部”= 1),相当于该省的访问减少(单位/106人)(0.65 vs 0.59;-9.2%),“西方”(0.97 vs 0.9;-7.2%)和“东方”(0.39 vs 0.35;-10.3%)通路。2013年,40%(4005/10 090)的研究在“东部”途径,服务于55%(2 066 079/4 629 051)的人口。2013年至2018年间,东部地区的人口增长(n = 286 781)超过西部地区(n = 168 469) 70% (n = 118 312)。到2018年,38%(7939/12 848)的研究在“东部”途径进行,然后为56%(2 849 753/5 084 301)的人口提供服务。在0-14岁的儿童中,“西方”的使用率(研究/103人)比“东方”的使用率高出约2.4倍。在> 14岁的患者中,在回顾期间,利用差异从1.78增加到1.98。结论:确保在同一医疗保健平台上提供公平的服务需要持续监测资源和人口分布。MR接入可以作为高度专业化服务公平性的代表。

Meckel's diverticulum is a true diverticulum of the alimentary tract occurring resulting from the persistence of remnants of the vitello-intestinal duct. They are often asymptomatic and incidentally diagnosed during surgery. Complications such as intestinal obstruction, diverticulitis, intestinal haemorrhage and perforation may occur with Meckel's diverticulum, which renders them symptomatic. The clinical and imaging diagnosis of Meckel's diverticulum is very challenging. As a result of the rare occurrence of complicated Meckel's diverticulum and the difficult preoperative diagnosis, knowledge of its imaging features is limited. The presented case series describes a spectrum of complications caused by Meckel's diverticulum and its CT imaging features. It highlights the importance of a high clinical suspicion by carefully searching for a Meckel's diverticulum on CT in its characteristic location to avoid missing it preoperatively.

梅克尔憩室是一种真正的消化道憩室,由黄肠管残余物的残留引起。它们通常是无症状的,在手术中偶然被诊断出来。梅克尔憩室可出现肠梗阻、憩室炎、肠出血和穿孔等并发症,使其出现症状。梅克尔憩室的临床和影像学诊断非常具有挑战性。由于复杂性梅克尔憩室罕见,术前诊断困难,对其影像学特征的认识有限。本文介绍了一系列由梅克尔憩室引起的并发症及其CT成像特征。它强调了高度临床怀疑的重要性,在CT上仔细寻找梅克尔憩室的特征性位置,以避免术前遗漏。

A case report of multinodular hepatic steatosis mimicking pseudotumors of the liver. 模拟肝脏假性肿瘤的多结节性肝脂肪变性1例。
IF 0.9 Q4 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2022-06-27 eCollection Date: 2022-01-01 DOI: 10.4102/sajr.v26i1.2410

Fatty liver disease (FLD) is a common, benign pathology often found incidentally. We present a clinical case in which metastatic liver disease was suspected on initial imaging studies. Following further investigations, a diagnosis of 'non-alcoholic fatty liver disease (NAFLD), multinodular type' was postulated. Subsequent histology confirmed the presence of liver steatosis. Multinodular type hepatic steatosis is a rare, but clinically important pathology to identify and differentiate from other multifocal lesions of the liver parenchyma.

脂肪肝(FLD)是一种常见的良性病理,经常偶然发现。我们提出一个临床病例,其中转移性肝病被怀疑在最初的影像学研究。根据进一步的调查,诊断为“非酒精性脂肪性肝病(NAFLD),多结节型”。随后的组织学证实肝脂肪变性的存在。多结节型肝脂肪变性是一种罕见的疾病,但对于鉴别和区分其他肝实质多灶性病变具有重要的临床意义。

Subpial haemorrhage is a rare cause of seizures in term neonates. A 3-day-old male infant, born at term with no history of perinatal hypoxia, presented with seizures and unremarkable physical examination in the interictal state. Imaging demonstrated left temporal subpial haemorrhage with the classic 'yin-yang sign' on MRI. The patient was subsequently diagnosed with factor XIII deficiency. Follow-up at 6 months and 12 months revealed encephalomalacia in the previous haemorrhagic areas with normal developmental milestones.

Background Hepatocellular carcinoma (HCC) can be diagnosed non-invasively, provided certain imaging criteria are met. However, the recent Liver Imaging Reporting and Data System (LI-RADS) version 2018 has not been widely validated. Objectives This study aimed to evaluate the diagnostic accuracy and reader reliability of the LI-RADS version 2018 lexicon amongst fellowship trained radiologists compared with an expert consensus reference standard. Method This retrospective study was conducted between 2018 and 2020. A total of 50 contrast enhanced liver magnetic resonance imaging (MRI) studies evaluating focal liver observations in patients with cirrhosis, hepatitis B virus (HBV) or prior HCC were acquired. The standard of reference was a consensus review by three fellowship-trained radiologists. Diagnostic accuracy including sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV) and area under the curve (AUC) values were calculated per LI-RADS category for each reader. Kappa statistics were used to measure reader agreement. Results Readers demonstrated excellent specificities (88% – 100%) and NPVs (85% – 100%) across all LI-RADS categories. Sensitivities were variable, ranging from 67% to 83% for LI-RADS 1, 29% to 43% for LI-RADS 2, 100% for LI-RADS 3, 70% to 80% for LI-RADS 4 and 80% to 84% for LI-RADS 5. Readers showed excellent accuracy for differentiating benign and malignant liver lesions with AUC values > 0.90. Overall inter-reader agreement was ‘good’ (kappa = 0.76, p < 0.001). Pairwise inter-reader agreement was ‘very good’ (kappa ≥ 0.90, p < 0.001). Conclusion The LI-RADS version 2018 demonstrates excellent specificity, NPV and AUC values for risk stratification of liver observations by radiologists. Liver Imaging Reporting and Data System can reliably differentiate benign from malignant lesions when used in conjunction with corresponding LI-RADS management recommendations.
背景:肝细胞癌(HCC)可以无创诊断,只要满足一定的影像学标准。然而,最近的肝脏成像报告和数据系统(LI-RADS) 2018版本尚未得到广泛验证。目的:本研究旨在评估LI-RADS 2018版词典在接受过奖学金培训的放射科医生中的诊断准确性和读者可靠性,并与专家共识参考标准进行比较。方法:回顾性研究时间为2018 - 2020年。总共获得了50项增强肝脏磁共振成像(MRI)研究,评估肝硬化、乙型肝炎病毒(HBV)或既往HCC患者的局灶性肝脏观察。参考标准是由三位接受过研究金培训的放射科医生达成的共识审查。诊断准确性包括敏感性、特异性、阳性预测值(PPV)、阴性预测值(NPV)和曲线下面积(AUC)值计算每个阅读器的每个LI-RADS类别。使用Kappa统计来测量读者的同意度。结果:阅读器在所有LI-RADS类别中表现出出色的特异性(88% - 100%)和npv(85% - 100%)。灵敏度是可变的,LI-RADS 1的灵敏度为67%至83%,LI-RADS 2的灵敏度为29%至43%,LI-RADS 3的灵敏度为100%,LI-RADS 4的灵敏度为70%至80%,LI-RADS 5的灵敏度为80%至84%。AUC值> 0.90时,阅读器对肝良恶性病变的鉴别准确率极高。总体的读者间一致性为“良好”(kappa = 0.76, p < 0.001)。两两读者间一致性“非常好”(kappa≥0.90,p < 0.001)。结论:2018年版LI-RADS对放射科医生肝脏观察的风险分层具有出色的特异性、NPV和AUC值。当与相应的LI-RADS管理建议结合使用时,肝脏成像报告和数据系统可以可靠地区分良恶性病变。

However, the recent Liver Imaging Reporting and Data System (LI-RADS) version 2018 has not been widely validated. Objectives This study aimed to evaluate the diagnostic accuracy and reader reliability of the LI-RADS version 2018 lexicon amongst fellowship trained radiologists compared with an expert consensus reference standard. Method This retrospective study was conducted between 2018 and 2020. A total of 50 contrast enhanced liver magnetic resonance imaging (MRI) studies evaluating focal liver observations in patients with cirrhosis, hepatitis B virus (HBV) or prior HCC were acquired. The standard of reference was a consensus review by three fellowship-trained radiologists. Diagnostic accuracy including sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV) and area under the curve (AUC) values were calculated per LI-RADS category for each reader. Kappa statistics were used to measure reader agreement. Results Readers demonstrated excellent specificities (88% – 100%) and NPVs (85% – 100%) across all LI-RADS categories. Sensitivities were variable, ranging from 67% to 83% for LI-RADS 1, 29% to 43% for LI-RADS 2, 100% for LI-RADS 3, 70% to 80% for LI-RADS 4 and 80% to 84% for LI-RADS 5. Readers showed excellent accuracy for differentiating benign and malignant liver lesions with AUC values > 0.90. Overall inter-reader agreement was ‘good’ (kappa = 0.76, p < 0.001). Pairwise inter-reader agreement was ‘very good’ (kappa ≥ 0.90, p < 0.001). Conclusion The LI-RADS version 2018 demonstrates excellent specificity, NPV and AUC values for risk stratification of liver observations by radiologists. Liver Imaging Reporting and Data System can reliably differentiate benign from malignant lesions when used in conjunction with corresponding LI-RADS management recommendations.","PeriodicalId":43442,"journal":{"name":"SA Journal of Radiology","volume":" ","pages":"2386"},"PeriodicalIF":0.9,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9210145/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40394727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pancreatic pseudocyst is a common complication that can occur following acute or chronic pancreatitis. Commonly, they are peripancreatic in location. Rarely, they can extend to the mediastinum, and further extension to the neck is even rarer. A 55-year-old man who presented with neck stiffness and dysphagia and on imaging, was found to have a cystic lesion in the neck. Aspiration of the lesion revealed raised amylase levels suggestive of a pancreatic pseudocyst.

胰腺假性囊肿是急性或慢性胰腺炎后常见的并发症。通常,它们位于胰腺周围。很少,它们可以延伸到纵隔,进一步延伸到颈部更是罕见。一名55岁男性患者表现为颈部僵硬和吞咽困难,影像学检查发现颈部有囊性病变。病灶穿刺显示淀粉酶水平升高,提示胰腺假性囊肿。

Intraductal papillary neoplasm of the bile duct (IPN-B) is a rare preinvasive intraductal pathology of the biliary tract. It should be differentiated from other more common benign or malignant causes of biliary obstruction and dilatation such as calculi or cholangiocarcinoma because the management and prognosis of this condition differs significantly. This case report describes a case of IPN-B in a 45-year-old female patient who presented with non-specific complaints of chronic abdominal pain without jaundice for three months.
胆管内乳头状肿瘤(IPN-B)是一种罕见的胆管内病变。它应与其他更常见的胆道阻塞和扩张的良性或恶性原因(如结石或胆管癌)区分开来,因为这种情况的处理和预后有很大不同。本病例报告描述了一例45岁女性IPN-B患者,其表现为慢性腹痛无黄疸三个月的非特异性主诉。
