In a series of 12 dogs having an acute experimental anterior myocardial infarct, the size of the infarct was measured using, successively, single photon emission transaxial tomography (SPETT) with thallium-201, conventional planar scintigraphy of the anatomic slices, and planimetry of these slices after nitroblue-tetrazolium (NBT) staining. The tomographic views were obtained after processing of projection images collected during the rotation of a scintillation camera around the animals. A correlation of 0.86 was obtained between SPETT and NBT staining for the whole series, and a value of 0.94 was observed when only the transmural infarcts were considered. These results suggest that SPETT of the myocardium labelled with thallium-201 should allow a reliable, rapid and atraumatic estimation of the infarct size.
在一组12只患有急性实验性前壁心肌梗死的犬中，依次使用含铊-201的单光子发射断层扫描（SPETT）、解剖切片的传统平面闪烁显像以及这些切片经氯化硝基四氮唑蓝（NBT）染色后的平面测量法来测定梗死面积。断层图像是在闪烁相机围绕动物旋转过程中采集的投影图像经过处理后获得的。整个系列中，SPETT与NBT染色之间的相关性为0.86，仅考虑透壁性梗死时观察到的值为0.94。这些结果表明，用铊-201标记心肌的SPETT应能对梗死面积进行可靠、快速且无创的估计。
