In 14 patients (4 in good health and 10 with coronary heart disease) a blood pool gated single photon emission computed tomography (SPECT) was executed. The transaxial slices of the cardiac blood pool were reconstructed. A three-dimensional surface display was employed for the analysis of the tomographic data. A fixed distance, a fixed threshold (50%), and some different planes of view were employed. The test permitted visualization of the ventricular and the atrial movements in all patients. The right ventricle was clearly seen in the right anterior oblique plane of view. The aortic beating was seen. In normal patients the left ventricle, clearly seen in left anterior oblique plane, shrank to a thin shank. In 4 patients with septum infarct the blood pool was seen to persist in the septum area in front of the lateral wall shrinking (akinesis). The opposite happened in patients with anterolateral wall coronary artery disease. Three-dimensional surface display of blood pool gated SPECT shows a real three-dimensional picture of the dynamic heart and is a new noninvasive approach to the heart patient.
对14例患者（4例健康者和10例冠心病患者）进行了血池门控单光子发射计算机断层扫描（SPECT）。重建了心脏血池的横断面切片。采用三维表面显示对断层扫描数据进行分析。采用固定距离、固定阈值（50%）和一些不同的观察平面。该检查可使所有患者的心室和心房运动可视化。在右前斜位观察平面可清晰看到右心室。可见主动脉搏动。在正常患者中，在左前斜位可清晰看到左心室，收缩至细柄状。4例有室间隔梗死的患者，可见血池在侧壁收缩（运动不能）前方的室间隔区域持续存在。前侧壁冠状动脉疾病患者则出现相反情况。血池门控SPECT的三维表面显示呈现出动态心脏的真实三维图像，是一种针对心脏病患者的新型非侵入性检查方法。
