In the past ten years we studied 80 patients with angina at rest by 201-Thallium perfusion scintigraphy. According to ECG changes during episodes of transient ischemia at rest, the patients were divided into three groups. Thirty six patients showed transient ST segment elevation (Group 1); 33 ST segment depression (Group 2) and 11 normalization of negative T waves (Group 3). 201-TI scintigraphy was performed during spontaneous or ergonovine induced episodes of ischemia and at redistribution. Group 1 showed localized and severe perfusion defects, well correlated to the site of ECG changes. Group 2 showed more diffuse and less severe perfusion defects, less correlated to the site of ECG changes. Group 3 showed perfusion defects similar to those observed in Group 1 and associated in 54% with basal perfusion defects due to previous myocardial infarction. In conclusion: A) three main perfusion patterns are associated with the three types of ECG changes; B) relative to ECG, myocardial scintigraphy provides a more accurate definition of the site and extension of ischemia, particularly in Group 2 patients.

Myocardial scintigram means a graphic record of the particles in the myocardium registered by a scintiscanner after administration of a radioactive isotope. It detects areas of increased or decreased metabolism (turnover). The test is performed to identify abnormal processes involving the myocardium such as tumor, infection, etc.

its a cardio-muscular recording or xray
so its an xray of the heart muscles
the "scinti" part refers to a flash or spark of light but i dont no where that wuld fit in
