TL;DR: This multicenter Phase I and II study indicates that planar [99mTc]HEXAMIBI stress imaging is safe and compares well with 201T1 stress imaging for detection of coronary artery disease.

TL;DR: Submaximal exercise 200T1 scintigraphy can distinguish high- and low-risk groups after uncomplicated acute myocardial infarction before hospital discharge and 201T1 defects in more than one discrete vascular region, presence of delayed redistribution, or increased lung thallium uptake are more sensitive predictors of subsequent cardiac events than ST segment depression, angina, or extent of angiographic disease.

TL;DR: In patients with CAD and severely depressed LV function, preoperative quantitative planar rest-redistribution 201TI imaging identifies viability in many asynergic myocardial segments, and these segments frequently improve function after CABG.

TL;DR: These data demonstrate that during radiofrequency catheter ablation, the radial temperature gradient is predictably hyperbolic and appears to be independent of intramyocardial perfusion if constant electrode temperature is maintained, and can accurately predict the ultimate size of radiofrequency‐induced lesions.

TL;DR: It is concluded that resting 201Tl scintigraphy may be useful in preoperative risk stratification for identification of patients more likely to benefit from surgical revascularization.
