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...

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...
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 alterna...
A clinicopathological study was performed in 23 patients who died from acute transmural myocardial infarction and who had been studied with thallium-201 during the acute phase. Twenty patients died within five days and three later than five days after scintigraphy. The scintigraphic location and the estimated size of infarction in vivo were correlated with postmortem findings. There was good ag...
conclusions these findings suggest that exposure to tc-99m could induce a radio-adaptive response against the exposure of tl-201. background low dose radiation will induce adaptation and following exposure to an adaptive dose, the cells are more resistance to following challenging doses. this phenomenon is known as radio-adaptive response. the aim of this study was to investigate the percentage...
A 33-year-old man with acquired immunodeficiency syndrome had an erosive supraglottic mass visible on CT scans of the neck; biopsy was postponed because of the patient's debilitated condition. Two weeks later, he was admitted with altered mental status; an MR image of the brain obtained at that time showed multiple bilateral mass lesions, the largest of which was 5 cm. Findings on a thallium-20...
