Evaluation of myocardial infarction by radioisotope myocardial imaging with special reference on thallium-201 myocardial perfusion imaging.

Japanese Circulation Journal, 1981
One hundred and three patients with myocardial infarctions were studied with 201-thallium chloride and/or 99m-technetium pyrophosphate myocardial imaging and were followed-up for an average of 23 months. There were 24 false negative cases with 201-thallium chloride, but no deaths or serious complications occurred during the follow-up period in these ...
