Historically, evaluation of the upper extremity vasculature was performed using digital subtraction angiography. With the advancement of cross-sectional imaging and submillimeter isotropic data acquisition, CT angiography (CTA) has become an excellent noninvasive diagnostic tool for evaluation of the vasculature of the upper extremities. CTA allows quick evaluation of vessel patency and irregularity and achievement of the anatomic detail needed in preoperative planning.

- The inferior mesenteric artery (IMA) and vein (IMV) are crucial for blood supply and drainage of the distal colon and rectum, but often overlooked in imaging due to their small size.
- The article discusses normal and abnormal appearances of these vessels, covering various vascular issues such as aneurysms, stenosis, and potential diagnostic clues that radiologists should be aware of.
- The authors emphasize the importance of recognizing the IMA and IMV in the context of gastrointestinal health and provide case examples to illustrate their relevance in diagnosing vascular abnormalities and collateral circulation.
Objectives: Acute appendicitis is a common surgical condition which is usually diagnosed on CT in adult patients, though MRI is frequently used as a first-line diagnostic test in pregnant patients due to its lack of ionizing radiation and superior ability to visualize the appendix compared to ultrasound. Interpretation of abdominal MRI exams in pregnant patients with suspected appendicitis is an important skill in clinical practice, but one that is difficult to become proficient at due to its relative infrequence, even in a high-volume practice.
Methods: We created a simulation-based platform built on an online radiology viewing platform (Pacsbin) for training residents and abdominal imaging fellows to interpret pregnant appendicitis MRI exams, which we made publicly available for use by trainees at any institution (forms.
Purpose: This study evaluates the prognostic value of CT findings, including volumetric measurements, in predicting outcomes for patients with Fournier gangrene (FG), focusing on mortality, ICU admission, hospital stay length, and healthcare costs.
Methods: A retrospective study was conducted on 38 FG patients who underwent CT scans before surgical debridement. We analyzed demographic data, CT volumetric measurements, and clinical outcomes using logistic and linear regression models.
Article Synopsis
- - The study aimed to identify CT scan characteristics of abdominopelvic Castleman disease, particularly focusing on a new finding related to the surrounding fat tissue (perinodal fat).
- - Researchers analyzed data from 76 adults with confirmed Castleman disease and evaluated factors like nodal mass size, enhancement patterns, and fat infiltration.
- - Results showed that a majority of cases had hypervascular nodal masses and fat infiltration, indicating that these features might help accurately diagnose Castleman disease, especially the hyaline vascular variant (HVV).
