2024年6月12日 · Inferior vena caval thrombosis is an essential diagnosis while evaluating any neoplastic lesion, or portal hypertension. It is also important to differentiate bland thrombus from tumor thrombus. A patient can present with many features which include. Inferior vena cava thrombus can be classified under two broad headings:

2024年6月12日 · The inferior vena cava (IVC) (plural: inferior venae cavae) is one of the great vessels that drains venous blood from the lower limbs, pelvis and abdomen into the right atrium of the heart. The inferior vena cava is formed by the confluence of the two common iliac veins at the L5 vertebral level.

2015年3月12日 · After a brief overview of IVC imaging techniques and embryologic features, cases in which computed tomography (CT) was performed with relevant correlates from magnetic resonance (MR) imaging, angiography, ultrasonography (US), and positron emission tomography (PET) will highlight the spectrum of congenital variants, neoplasms, and other entities...

IVC anomalies should be suspected in patients presenting with pulmonary emboli, chronic pain, and deep vein thrombosis. To correctly characterize and classify IVC anomalies and variations is of crucial importance for proper planning of surgical interventions and thus for …

2024年10月16日 · Duplication of the inferior vena cava is a relatively rare but well described vascular anomaly. This caval abnormality had an increased association with renal anomalies like crossed fused ectopia or circumaortic renal collar 1,2. The incidence of inferior vena cava duplication is reported to be ~1.5% (range 0.2-3%) 3.

Axial arterial phase contrast-enhanced CT showing penetration of multiple IVC filter legs both anteriorly and posteriorly, contacting the adjacent intervertebral disc (black and white arrows).

The use of IVC filters has become very common as an alternative and/or as a supplement to anticoagulation, and these filters are often seen on routine abdominal CT, including in the emergency setting; therefore, knowledge of the normal spectrum of findings of IVC filters by the radiologist on CT is critical.

2024年6月14日 · 头颅磁共振（MRI）在识别脑血管性损伤、鉴别认知障碍病因方面 的灵敏度高于电子计算机断层扫描（CT），被视为 VCI 影像诊断的“金标准”。

2021年8月12日 · 摘要：目的:分析血管性认知障碍 (VCI)CT灌注成像 (CTP)不同部位的脑灌注参数值差异及其危险因素.方法:选取医院收治的80例VCI患者,均经CT或MRI检查确诊,根据患者简易精神状态检查法 (MMSE)和画钟测试进行认知功能评定,并按认知功能评定结果将其分为血管性痴呆 …

2016年11月3日 · Neuroimaging provides important information on the neuroanatomical substrate of the disorder, plays an important role in the diagnosis, and adds to the prediction of VCI. Most acute stroke patients undergo brain imaging by computed tomography (CT); thus, studies using CT are representative of the whole clinical population.
