Scintigraphic anatomy of coronary artery disease in digital thallium-201 myocardial images.

Scintigraphic anatomy of coronary artery disease in digital thallium-201 myocardial images.

One hundred and eight patients with single and multiple vessel coronary artery disease confirmed by arteriography were evaluated by exercise thallium-201 (201Tl) myocardial scintigraphy to determine the scintigraphic appearances of specific coronary stenoses. In general proximal stenoses caused more widespread, but not necessarily more severe, myocardial tracer deficit than distal stenoses. In ...

THALLIUM-201 STRESS TEST IN 156 PATIENTS WITH SUSPECTED CORONARY ARTERY DISEASE

Currently, myocardial TI-201 scintigraphy is most often performed in conjunction with exercise stress testing in patients with suspected or known CAD. Stress thallium tests were performed for 156 patients with and without old myocardial infarctions complaining of chest pain. All of them underwent contrast coronary angiography. Perfusion defects were mostly manifested as reversible defects ...

Angiographic and hemodynamic determinants of myocardial ischemia during adenosine thallium-201 scintigraphy in coronary artery disease.

BACKGROUND Myocardial ischemia attributed to coronary steal may occur in some patients receiving pharmacological coronary vasodilation. ECG ST-segment depression is a marker of myocardial ischemia in these patients, but the factors determining the presence or absence of ischemia are not well known. METHODS AND RESULTS To examine the angiographic, hemodynamic, and scintigraphic determinants of...

Thallium--201 myocardial imaging in Kawasaki disease.

Myocardial imaging using thallium-201 was performed in patients with Kawasaki disease. In two patients whose ECGs showed ischemic changes, the scintiscan demonstrated an area with diminished radioactivity at the site corresponding to electrocardiographic localization of the infarction. Thallium-201 myocardial imaging is useful in the diagnosis of myocardial infarction not only in adults but als...
