Imaging agent catches acute venous thromboembolism missed by other methods

Anterior maximum-intensity projections of 18F-GP1 PET/CT over 120 min show positive 18F-GP1 accumulation in pulmonary arteries (arrows) and in proximal (dotted arrows) and distal (arrowheads) veins of leg, which are gradually distinct on late images as 18F-GP1 activity from other organs is excreted via both urinary and hepatobiliary tracts.

When diagnosing acute venous thromboembolism (VTE)—a disease that includes deep-vein thrombosis of the leg or pelvis and its complication, pulmonary embolism—PET/CT imaging with a 18F-GP1 radiotracer performed with a higher detection rate than conventional imaging, according to research published in The Journal of Nuclear Medicine.
