title: The use of thallium-201 myocardial scintigraphy for the diagnosis of previous infarction.
abstract: The ability of thallium-201 scintigraphy to detect previous infarction (greater than 6 months ago) was studied in 43 patients with coronary artery disease, 39 with valvular heart disease, and 5 with cardiomyopathy or myocarditis. All patients had undergone selective coronary arteriography and left ventricular angiography. Thallium-201 scintigraphy at rest proved a very sensitive method for detecting previous infarction, also clinically silent. Scintigraphy was more sensitive than a recent ECG. However, scintigraphy can give falsely positive results.
