Myocardial perfusion imaging with thallium-201

Over the past 15 yr, numerous clinical studies have validated the use of myocardial perfusion imaging with 201Tl for detection and evaluation of coronary artery disease (CAD). In addition, 201Tl scintigraphy plays a valuable role in the risk stratification of patients with suspected or

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.

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.

2010-3-1  THALLIUM PROTOCOLS. The protocol used for so many years before the introduction of the 99m Tc-labeled myocardial perfusion imaging tracers is a stress/redistribution 201 Tl protocol. It is standard to use low-energy general-purpose collimators for this protocol; however, the use of low-energy high-resolution collimators is certainly an alternative.

Thallium-201 is comparable to technetium-99m-sestamibi

2015-11-1  With its physical property of ideal energy peak for the Anger camera, technetium-99m-sestamibi (MIBI) is the preferred agent for G-SPECT. Nevertheless, thallium-201 (Tl-201) remains the mainstay for myocardial perfusion imaging (MPI) in Taiwan despite the distinctive benefits of MIBI.
