F-18-FDG Uptake and Calcifications in the Thoracic Aorta on Positron Emission Tomography/Computed Tomography Examinations Frequency and Stability on Serial Scans
(Lippincott Williams & Wilkins, 2011-02-01)
Purpose: Vascular F-18-2-fluoro-2-deoxy-D-glucose (F-18-FDG) uptake has been suggested as a means of identifying metabolically active atheroma, whereas vascular calcification is accepted as an indicator of atherosclerosis. ...
