The preliminary clinical uses of

131

I-mIBG in 13 cases of adrenal medulla imaging and 6 cases of myocardial infarction imaging were reported. Normal myocardial imaging or no imaging was obtained in the former cases

while radioactive defect was found in infarcted site. It is thus suggested that

131

I-mIBG myocardial imaging would be helpful for the diagnosis of myocadial infarction. Besides

it may be also used in diagnosis of pheochromcytoma and the investigation of catechclamine metabolism in myocardium.
