Coronary CT angiography (CCTA) is a noninvasive imaging modality which can be used to evaluate the anatomy of the coronary arteries. Unlike coronary artery calcium scoring, which utilizes noncontrast CT to assess atherosclerotic disease burden, CCTA allows direct visualization of the coronary artery wall and lumen with the administration of intravenous contrast. The degree of coronary luminal stenosis can be reliably estimated, as can the presence or absence…

The recent discovery of a link between Nephrogenic Systemic Fibrosis (NSF) and the administration of gadolinium contrast for MRI examinations has sent the imaging world scrambling. NSF is a debilitating fibrosing reaction primarily involving the skin and, to a variable degree, internal organs. While longitudinal studies currently do not exist to help determine which patients can be safely administered gadolinium, it is clear that severe renal dysfunction, including those patients on…
