Practical Reviews

Per-Patient, Per-Segment Evaluation of GCA on CTA, FDG PET-CT

Background: Giant cell arteritis (GCA) is a systemic vasculitis affecting the carotid arteries and also involves the large vessels. Vessel wall thickening and stenosis/dissection/dilatation can be identified on aortic CT angiography (CTA). Circumferential and homogenous vascular uptake is seen on fluorodeoxyglucose (FDG)-PET/CT scan. Objective: To compare and evaluate the diagnostic performance of aortic CTA and FDG-PET/CT in detection of GCA. Design: Multicenter retrospective stud more...
