Abstract
PURPOSE: The purpose was to show the feasibility of F-18 choline positron emission tomography (PET) angiography for the evaluation of abdominal and iliac arteries. METHODS: Thirty-five patients were examined and image quality was scored. Findings were correlated with contrast-enhanced computed tomography. RESULTS: Image quality was best in the aorta and common iliac arteries (100% and 93% of vessels). Negative predictive values of PET angiography were excellent (100%), and positive predictive values were impaired by disease overestimation. CONCLUSION: PET angiography is technically feasible and of good image quality in large arteries. In selected cases, it may become an alternative to established angiographic methods.
