Horinouchi H, Sofue K, et al. - This imaging study was conducted to investigate the utility of whole-aorta CT angiography (CTA) with 15 mL contrast material (CM) on time-resolved imaging for endovascular abdominal aortic repair (EVAR). Researchers enrolled a total of 26 individuals with a high-risk of post-contrast acute kidney injury (PC-AKI) who underwent CTA with 15 mL CM using temporal maximum intensity projection (tMIP-CTA) generated from time-resolved imaging. Two independent reviewers assessed the arterial diameters in unenhanced CT and tMIP-CTA images, and image quality was estimated on a 5-point scale. This study further evaluated presence of the accessory renal artery, inferior mesenteric artery (IMA) occlusion, and instructions for use (IFU) of EVAR. Whole-aorta tMIP-CTA on time-resolved imaging was found to be beneficial for maintaining contrast enhancement and image quality for EVAR planning, and can substantially reduce the amount of CM.
