Biplane Fourier amplitude and phase images from radionuclide ventriculograms were analyzed for the presence of regional wall motion abnormalities in 25 patients who had a total of 33 healed myocardial infarctions (nonviable scar tissue) documented by contrast ventriculography and ECG. This indirect evidence was validated by MRI, which permits direct visualization of healed myocardial infarction. The use of amplitude and phase images in both projections resulted in the detection of more healed myocardial infarctions (91%) than did the use of conventional radionuclide ventriculography with left anterior oblique images alone (67%), because inferior wall infarcts are more readily visualized in the left posterior oblique projection.
对25例患者的放射性核素心室造影双平面傅里叶振幅和相位图像进行分析，以检测局部室壁运动异常。这些患者经对比心室造影和心电图证实共有33处陈旧性心肌梗死（无活性瘢痕组织）。这种间接证据通过MRI得到了验证，MRI可直接观察到陈旧性心肌梗死。使用两个投照角度的振幅和相位图像检测到的陈旧性心肌梗死（91%）比仅使用常规放射性核素心室造影左前斜位图像（67%）更多，因为下壁梗死在左后斜位投照中更容易显示。
