In vitro computed tomography (CT) was performed on nine human hearts. Mean attenuation coefficients from a 2.5 X 2.5-cm area of the left ventricular wall were determined from a 160 X 160 computer printout before and after formalin fixation in five hearts. These values averaged 27.1 and 24.7 units, respectively (p less than 0.05). The absorption characteristics of normal human myocardium do not differ from those observed in animals and the potential of CT application to ischemic heart disease can be assessed by this mehtodology applied to postmortem hearts of patients with myocardial infarction of varying duration.
对九颗人类心脏进行了体外计算机断层扫描（CT）。在五颗心脏中，从160×160的计算机打印输出中确定了左心室壁2.5×2.5平方厘米区域的平均衰减系数，分别在福尔马林固定前后进行测定。这些值分别平均为27.1和24.7单位（p小于0.05）。正常人类心肌的吸收特性与在动物中观察到的没有差异，并且通过应用于不同病程心肌梗死患者的尸检心脏的这种方法，可以评估CT在缺血性心脏病中的应用潜力。
