Fifty patients with acute chest pain had thallium-201 myocardial imaging performed three to six days after emergency admission to hospital. The image was abnormal in 20 out of 22 patients with acute transmural myocardial infarcts but in only 1 of 5 with acute subendocardial infarcts. Indistinguishable scan abnormalities caused by old infarcts were seen in 7 patients, and caused by myocardial is...

This study was undertaken to examine the ability of SPECT in differentiation of a pulmonary lesion suspecions of lung cancr. A total of 170 patients with suspected lung cancer were studied. A dose of Tl-201 chloride {148-296 MBq) was injected intravenously and tomographic early and delayed scans were obtained at 15 miniutes and 3 hours post injection, respectively. Delayed Tl-201 SPECT vi...

To determine whether the severity of thallium-201 scintigraphic defects present within hours of acute myocardial infarction (MI) could he used to predict subsequent mortality, thallium-201 imaging was performed within 15 hours of the onset of symptoms in 42 patients with acute MI. Patients with pulmonary edema or shock were excluded. The extent of perfusion defect was determined in three views ...

Tc-99m-MIBI is an isonrtrile derivative used for evaluation of myocardial perfusion in recent years. In this preliminary report, 7 patients with coronary artery disease are evaluated with Tc-99m-MlBl stress planar and sped studies. Good correlation with coronary angiography is observed in these cases. In view of inherent technical problems present with thallium 201, Tc-99m-MIBi is a good ...

Introduction: Meningioma is usually a benign brain tumor, but sometimes with aggressive course. The aim of this study was to assess the ability of 201Tl Brain SPECT to differentiate the pathologic grade of meningioma preoperatively. Methods: Thirty lesions in 28 patients were evaluated in this study. Early (20 minutes) and late (3 hours) brain SPECT images were performed and early u...
