A new method of ECG gated cardiac blood pool SPECT to illustrate the left ventricular (LV) wall motion in a single static image, two dimensional polar display (2DPD), was described. Circumferential profiles of the difference between end diastolic and end systolic short axis images of the LV were displayed in a similar way to the bull's eye plot of 201Tl myocardial SPECT. The diagnoses by 2DPDs agreed with those by cinematic displays of ECG gated blood pool SPECT in 74 out of 84 segments (85.5%) of abnormal motion, and 155 our of 168 segments (80.3%) of normal motion. It is concluded that 2DPD can evaluate regional wall motion by a single static image in a significant number of patients, and is also useful in comparing with the bull's eye image of 201Tl myocardial SPECT.
描述了一种新的心电图门控心血池单光子发射计算机断层扫描（SPECT）方法，即二维极坐标显示（2DPD），用于在单个静态图像中显示左心室（LV）壁运动。左心室舒张末期和收缩末期短轴图像之间差异的圆周轮廓以类似于201Tl心肌SPECT的靶心图的方式显示。在84个异常运动节段中的74个（85.5%）以及168个正常运动节段中的155个（80.3%）中，2DPD的诊断结果与心电图门控心血池SPECT的电影显示结果一致。结论是，2DPD可以在大量患者中通过单个静态图像评估局部壁运动，并且在与201Tl心肌SPECT的靶心图像比较时也很有用。
