In an attempt to evaluate the possible usefulness of transmission computed tomography, CT scans of the chest of a series of dead dogs were obtained by means of an EMI body scanner. The sections thus obtained with and without the injection of contrast material reveal a great deal of cardiac morphology. Infarcts of the heart produced prior to scanning were imaged as regions of lower x-ray attenuation. The hearts of a series of live dogs following infarction were imaged by means of a positron emission transverse tomomograph (PETT) following administration of C-palmitate. The images permitted assessment of the relative size of the infarct. The relative advantages of transmission and emission tomography in cardiac visualization are discussed.
为了评估透射计算机断层扫描的潜在用途，利用EMI全身扫描仪对一系列死亡犬的胸部进行了CT扫描。在注射造影剂和未注射造影剂的情况下所获得的断层图像揭示了大量心脏形态信息。扫描前产生的心脏梗死灶成像为X线衰减较低的区域。一系列梗死存活犬在注射C-棕榈酸酯后，通过正电子发射横向断层扫描仪（PETT）进行成像。这些图像有助于评估梗死灶的相对大小。文中讨论了透射断层扫描和发射断层扫描在心脏成像方面的相对优势。
