WebJun 23, 2000 · The use of thallium is limited as it is a toxic element. Thallium sulphate is employed as a rodent killer - it is odorless and tasteless - but household use of this poison has been prohibited in the USA. Thallium oxide is used to produce glasses with a high index of refraction, and also low melting glasses which become fluid at about 125K. WebAs previously demonstrated in thallium imaging, the sensitivity of the 2DE technique for CAD detection is enhanced in patient subsets with multivessel CAD or prior myocardial infarction. In addition, the sensitivity of exercise echocardiography is decreased in patients with resting wall motion abnormalities. WebResting thallium defects were found in 105 segments (58 percent). The mean number of segments with resting thallium defects per patient was 5.3±2.0 (range, 2 to 9; median, 5.5). new york playwriting contests

WebReverse redistribution (RR) of thallium-201 has been associated with both acute and healed myocardial infarction, and with recent thrombolysis. The physiologic basis for RR in coronary artery disease (CAD) is unclear but may be related to an admixture of viable and scarred myocardium within the RR segment. We performed thallium reinjection imaging at rest to …

WebNov 8, 2024 · For the simultaneous acquisition protocol, the resting thal-lium-201 and stress technetium-99m perfusion images are acquired at the same time. This protocol simplifies acquisition and relies on the use of multiple energy windows to acquire the lower-energy thallium-201 at the same time as the higher-energy technetium-99m.
