A gated blood-pool equilibrium radionuclide angiography was performed in a patient to determine the ejection fraction for doxorubicin cardiotoxicity evaluation. The phase image of the first harmonic of the Fourier analysis revealed a severe delay of the right ventricular contraction compared with that of the left ventricle. This right ventricular contraction asynchronism was due to a large pericardial effusion, confirmed by the presence of the halo sign on the summed gated images and by echocardiography. The phase delay moves towards normalization after pericardiocentesis. Although radionuclide angiocardiography is not the best method for identification of pericardial effusion, this diagnosis should be evoked when a severe homogenous delay of the right ventricular contraction is observed.
对一名患者进行了门控心血池平衡放射性核素血管造影，以确定射血分数，用于评估阿霉素的心脏毒性。傅里叶分析一次谐波的相位图像显示，与左心室相比，右心室收缩严重延迟。这种右心室收缩不同步是由于大量心包积液所致，门控图像总和上的晕轮征以及超声心动图证实了这一点。心包穿刺术后相位延迟趋于正常。尽管放射性核素心血管造影不是识别心包积液的最佳方法，但当观察到右心室收缩出现严重均匀延迟时，应考虑这种诊断。
