AB The moving imaging table of a large field-of-view (LFOV) scintillation camera was applied to venography. The abnormal findings in 10 out of 27 patients with suspected venous disease of the legs studied by radionuclide venography of the lower extremities included venous occlusion, collateral circulation, and/or lung perfusion defects. Technetium-99m-MAA was simultaneously injected in the pedal vein of each foot with and without tourniquets. The LFOV camera is set on “scan mode” which synchronizes the moving table with image acquisition. Leg veins, iliac veins, inferior vena cava and lungs are imaged in one view sequentially. Advantages of this technique are: 1) reducing of the number of radiopharmaceutical injections and amount of the administered dose; 2) obtaining better anatomic presentation of the images; and 3) detecting perfusion defects in the anterior view of the lungs to alert the need for performing additional views.
