Reverse redistribution is revealed on exercise 201Tl myocardial SPECT in some cases with hypertrophic cardiomyopathy. Ten patients with hypertrophic cardiomyopathy without coronary artery disease who showed reverse redistribution visually were studied. Reverse redistribution was evaluated by the early and delayed images of exercise 201Tl myocardial SPECT. Relation between reverse redistribution and distribution of left ventricular hypertrophy estimated by echocardiography and magnetic resonance imaging was investigated, and the mechanism of reverse redistribution was analyzed by referring to Bull's eye display of washout rate. Reverse redistribution was displayed in non-hypertrophic region and washout rate was normal in that region and low in hypertrophic region. In conclusion, in order to interpret reverse redistribution it is necessary to recognize hypertrophic region and to refer to washout rate.
在某些肥厚型心肌病病例中，运动201铊心肌单光子发射计算机断层扫描（SPECT）显示有反向再分布。对10例无冠状动脉疾病且肉眼可见反向再分布的肥厚型心肌病患者进行了研究。通过运动201铊心肌SPECT的早期和延迟图像评估反向再分布。研究了反向再分布与经超声心动图和磁共振成像估计的左心室肥厚分布之间的关系，并通过参考洗脱率的靶心图分析了反向再分布的机制。反向再分布出现在非肥厚区域，该区域的洗脱率正常，而肥厚区域的洗脱率较低。总之，为了解释反向再分布，有必要识别肥厚区域并参考洗脱率。
