Why the study?
Does Thallium 201 myocardial scintigraphy improve the detection of ischemic heart disease in patients with cardiac disorders?
Does Thallium 201 myocardial scintigraphy improve the detection of ischemic heart disease in patients with cardiac disorders?
Thallium 201 myocardial scintigraphy, particularly when combined with exercise testing, is a valuable noninvasive tool with high diagnostic accuracy for ischemic heart disease.
May support noninvasive ischemic detection with exercise thallium-201; leaves open prospective validation versus modern modalities.
Myocardial scintigraphy with thallium 201 is a simple, safe, and valuable noninvasive technique in evaluating the condition of patients with cardiac disorders. Images obtained at rest appear to have limited usefulness at the present time. However, rest imaging may prove to have advantages in the future for early diagnosis of myocardial infarction, thus aiding in the selection of patients to be admitted to the coronary care unit. Exercise imaging, on the other hand, has a high degree of sensitivity and specificity in detecting ischemic heart disease; when combined with treadmill exercise testing, imaging improves the diagnostic accuracy even further.
