Division of Trauma and Emergency Surgery, Department of Surgery, Chang Gung Memorial Hospital, No. 5, Fuxing St., Guishan Dist., Taoyuan City, 333, Taiwan.
Purpose: This study investigates the risk of contrast-associated acute kidney injury (CA-AKI) in trauma patients, focusing on the impact of cumulative contrast medium doses.
Methods: A retrospective review was conducted at a level 1 trauma center (2019-2021). The study included patients who underwent intravascular contrast-enhanced examinations for torso trauma within 7 days post-injury.

A 52-year-old man with a short chronic total occlusion in the left superficial femoral artery underwent drug-coated balloon (DCB) angioplasty. Evaluation using integrated backscatter intravascular ultrasound revealed that the plaque volume of fibrosis was compressed just after treatment (from 494.67 mm to 398.

Cardiac allograft vasculopathy (CAV) remains a significant challenge after heart transplantation, necessitating effective surveillance methods. This review centers around the role of coronary computed tomography angiography (CCTA) in CAV surveillance, given its unique capabilities to visualize and quantify CAV in comparison with other imaging modalities, including invasive coronary angiography and intravascular ultrasound. CCTA has shown good diagnostic performance for detecting and monitoring CAV, exemplified by a higher sensitivity and negative predictive value compared with invasive coronary angiography.

Porcine eyes were examined using postmortem computed tomography (PMCT) under controlled postmortem time and temperature conditions to assess the mechanisms and timing of changes in ocular structure. Eight porcine heads were halved, and PMCT scans were conducted from postmortem interval (PMI) days 0 to 13. CT images were obtained to evaluate the vitreous volumes, vitreous CT values, axial lengths of the eyes, lens dislocation, and intraocular gas.
