The regional myocardial distribution of 131I-16-iodo-9-hexadecenoic acid (131I-HA) and 201Tl-thallium chloride (201TlCl) was determined in normal dogs and after occlusion of a coronary artery. The uptake of 131I-HA was about 20% lower than that of 201TlCl but the ratio 201Tl/131I was the same for the whole myocardium within narrow limits for normal as well as infarcted tissue. The potential of 123I-HA as a radiopharmaceutical for diagnosis of myocardial defects is discussed.
在正常犬以及冠状动脉闭塞后，测定了131I-16-碘-9-十六碳烯酸（131I-HA）和201Tl-氯化铊（201TlCl）的区域性心肌分布。131I-HA的摄取量比201TlCl低约20%，但对于正常组织和梗死组织，整个心肌的201Tl/131I比值在狭窄范围内是相同的。讨论了123I-HA作为诊断心肌缺损的放射性药物的潜力。
