Abstract

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%, predicitive 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.

摘要

本研究旨在明确放射性核素血管造影上心包填塞的征象。首次通过研究在大视野γ相机上进行，使用高锝酸盐团注。分析了372项研究。其中28项研究当时存在需要手术干预的心包填塞。放射性核素血管造影上心包填塞的诊断征象为：（1）右心室受压——敏感性82%，特异性97%，阳性结果预测值72%，阴性结果预测值99%；（2）右心房受压——敏感性21%，特异性99%，阳性结果预测值75%，阴性结果预测值94%。放射性核素血管造影可准确诊断心包填塞，从而提示那些需要紧急引流的心包积液。
