Abstract
Leg scanning is now routinely performed in most laboratories in conjunction with lung perfusion studies since thrombi arising in the deep veins of the lower extremities are a major cause of pulmonary emboli. However, dynamic leg scintigraphy, i.e., visualization of venous blood flow in the lower extremities, has not been practical because the area observed by the detectors of earlier model scintillation cameras was unsatisfactory. The more advanced large field-of-view scintillation camera with a synchronized scanning table simplifies the performance of dynamic leg scintigraphy. Our experience with such an instrument is described.
