Abstract

The cardiac photoscan is a helpful diagnostic tool for the evaluation of suspected pericardial effusion, particularly with critically ill patients who cannot tolerate angiography. This innocuous procedure can be performed in a few minutes with the use of sodium pertechnetate Tc 99m as the source of radioactivity. In one study, a life-threatening, loculated pericardial effusion was demonstrable only by the photoscan.
