MR-tomography (MRT) was used to investigate 10 isolated hearts from patients who died of various cardiovascular diseases. The purpose was to study the accuracy of MRT for determination of the myocardial mass (MM) of the left and right ventricles. MM was calculated using Simpson's method and the "area-length" formula. The first method demonstrated a high correlation of MRT results with autopsy findings with relation to the left, right ventricles and the interventricular septum (r = 0.98, 0.88, 0.85, respectively). The accuracy of the second method was also very high (r = 0.96 with relation to the left ventricle), however great scattering of MM values with relation to true values was noted. MRT can serve as a highly informative method in the evaluation of the ventricular MM and the time course of its changes.
采用磁共振断层扫描（MRT）对10例死于各种心血管疾病患者的离体心脏进行研究。目的是探讨MRT测定左、右心室心肌质量（MM）的准确性。MM采用辛普森法和“面积-长度”公式计算。第一种方法显示，MRT结果与尸检结果在左心室、右心室和室间隔方面具有高度相关性（r分别为0.98、0.88、0.85）。第二种方法的准确性也很高（与左心室相关的r = 0.96），然而，MM值相对于真实值存在较大离散度。MRT可作为评估心室MM及其变化时间过程的一种信息丰富的方法。
