Patients with hypertension may present with symptoms of angina with or without coronary artery disease (CAD). The pretest likelihood for coronary artery disease increases with concomitant diabetes mellitus, hypercholesteremia, and other risk factors. Standard noninvasive evaluation in patients with a high likelihood of CAD includes stress (exercise or persantine) electrocardiography and SPECT t...

Background. Exercise-induced abnormalities during thallium-201 scintigraphy that normalize at rest frequently occur in patients with hypertrophic cardiomyopathy. However, it is not known whether these abnormalities are indicative of myocardial ischemia. Methods and Results. Fifty patients with hypertrophic cardiomyopathy underwent exercise 20UT1 scintigraphy and, during the same week, measureme...

OBJECTIVE To determine the best test(s) for predicting functional recovery of hibernating myocardium after reperfusion. METHODS A prospective study to compare echocardiographic left ventricular diastolic wall thickness (> or =5 mm), low-dose dobutamine echocardiography and rest-redistribution thallium-201 scintigraphy, alone and in combination, for predicting recovery of left ventricular akin...

Introduction: Thallium-201 (Tl-201) is routinely administered to people undergoing nuclear medicine scans at activity levels of 3-5 milli curies (mCi). Due to its short halflife, relatively low hazard radiations and rapid biological excretion, thallium-201 has very low radio toxicity when introduced internally. However, the recommended dose of Tl-201 is considered clinical safe and gets excrete...

The object of this review is to provide information about (201)Tl-thallous chloride in radionuclide myocardial perfusion imaging. This technique has experienced a recent resurgence because of the shortage of (99m)Tc. After reading this article, the technologist will be able to describe the properties and uptake mechanism of (201)Tl, the procedure for myocardial perfusion imaging with this agent...
