Clinical assessment of myocardial perfusion with thallium

Clinical assessment of myocardial perfusion with thallium-201. Wackers FJ (1). Assessment of myocardial perfusion and coronary blood flow in man can be performed reliably and successfully using thallium-201 imaging. The extent of exercise myocardial perfusion abnormalities reflects the functional significance of coronary artery stenosis.

Clinical indications for thallium-201 myocardial perfusion

Thallium -201 myocardial perfusion scanning can assess regional myocardial perfusion noninvasively. As it is both time-consuming and expensive its use should be restricted to specific diagnostic problems. The clinical indications in known or suspected coronary artery disease are reviewed. In suspect

[Myocardial perfusion in coronary disease: thallium-201

Both thallium-201 and exercise ECG had a similar sensitivity in patients with obstruction of three coronary vessels. In patients with obstruction of one or two vessels, thallium-201 imaging clearly showed a regional hypoperfusion corresponding to the specific perfusion coronary vessels, while exercise ECG gave aspecific topographic results.

2017-4-21  Background Thallium-201 washout rate of stress myocardial perfusion imaging (MPI) has been reported to correlate with coronary flow reserve which is a parameter of myocardial microcirculation. However, the evidence for its use in diabetic kidney disease (DKD) has been lacking, and the association between thallium-201 washout rate and adverse outcomes including death is unknown. Therefore, the

Experimental studies have been made of lesion detectability in myocardial perfusion studies using thallium-201. A series of images (AP view) was generated mathematically. Images were simulated with 100k, 200k, and 300k counts for the complete image and either non- or half-perfused lesions (lesion volume 1–61/2% of total myocardial volume). In addition thallium images were generated excluding

Thallium-201 is a potassium analogue that is taken up by viable myocardial cells in direct proportion to coronary blood flow. The initial thallium injection is performed at peak stress, when hypoperfused myocardium will have less uptake than myocardium with normal perfusion.

Comparison of Technetium-99m Tetrofosmin and Thallium

1998-2-1  Technetium-99m (Tc-99m) tetrofosmin is a lipophilic, cationic perfusion agent that, like Tc-99m sestamibi, is an alternative to thallium-201 (Tl-201) for stress imaging. Experimental animal studies have demonstrated that the myocardial extraction of Tc-99m tetrofosmin plateaus at flow rates >1.7 × normal 1, 2. This plateau is reached earlier
