Three-dimensional vessel wall MR imaging has gained popularity in the diagnosis and management of patients with cerebrovascular disease in clinical practice. Vessel wall MR imaging is an imaging technique that delivers a fundamentally different viewpoint by emphasizing on the pathology of the vessel wall as opposed to traditional descriptions that focus on the vessel lumen. It shows a crucial power in detecting vessel wall changes in patients with diseases including, but not limited to, central nervous system vasculitis, moyamoya disease, aneurysms, dissections, and intracranial atherosclerotic disease.

Purpose: To develop and validate an integrated model based on MR high-resolution vessel wall imaging (HR-VWI) radiomics and clinical features to preoperatively assess periprocedural complications (PC) risk in patients with intracranial atherosclerotic disease (ICAD) undergoing percutaneous transluminal angioplasty and stenting (PTAS).
Methods: This multicenter retrospective study enrolled 601 PTAS patients (PC+, n = 84; PC -, n = 517) from three centers. Patients were divided into training (n = 336), validation (n = 144), and test (n = 121) cohorts.

Single coronary ostium and intramural coronary artery variations in patients with transposition of the great arteries significantly increase the mortality and morbidity after arterial switch operation (ASO). In these patients, the classic coronary button implantation may cause kinking or twisting of the coronary artery which can cause coronary insufficiency. This case series presents two patients, a 15-month-old girl with transposition of the great arteries and a 10-month-old boy with a Taussig-Bing anomaly.

Pancreatogastric fistulas are rare but serious complications of chronic pancreatitis that can lead to life-threatening gastrointestinal bleeding due to erosion of nearby blood vessels. We present a case of a 43-year-old man with chronic calcific pancreatitis and a history of alcohol misuse, who experienced recurrent hematemesis and melena over 2 months. Despite multiple endoscopies and transfusions, the bleeding source remained unidentified until imaging revealed a fistulous tract between the pancreas and the posterior gastric wall.

Intra-aneurysmal thrombus formation is crucial for the healing of endovascularly treated aneurysms. This study evaluated whether T1-weighted black blood imaging can monitor thrombus formation by examining the relationship between chronological signal intensity changes and aneurysm occlusion status after flow diverter stenting and coil embolization. We retrospectively analyzed 78 patients with 83 aneurysms (flow diverter stenting: 28, coil embolization: 55) who underwent T1-weighted black blood imaging at 1 week, 3 months, and 6 months post-treatment.

Background: Carotid web (CaW) is a rare fibromuscular dysplasia lesion at the carotid bifurcation linked to thromboembolic events in young patients. CaW-induced hemodynamic disturbances contribute to thrombosis, but the impact of CaW morphology on long-term thrombotic risk remains unclear.
Method: This study developed three-dimensional numerical models based on patient-specific carotid artery anatomy with CaW angles of 30°, 60°, and 90° (models A, B, and C).
