Summary: This study was performed to define the signs of cardiac tamponade on radionuclide angiography. The first pass studies were performed on a large field gamma camera, using a bolus of technetium pertechnetate. Three hundred and seventy‐two studies were analysed. Cardiac tamponade requiring surgical intervention was present at the time in 28 studies The diagnostic signs of cardiac tamponade on radionuclide angiography were: (1) Right ventricular compression—sensitivity 82%, specificity 97%, predictive value of a positive result 72%, predictive value of a negative result 99%, and (2) Right atrial compression—sensitivity 21%, specificity 99%, predictive value of a positive result 75%, predictive value of a negative result 94%. Cardiac tamponade can be accurately diagnosed on radionuclide angiography and thus indicate those pericardial effusions which require urgent drainage.
