Rest—redistribution thallium201 scintigraphy to determine
cardial thallium201 uptake is a marker of both regional perfusion and viability Because stress testing is not appropri ate in the first few days after myocardial infarction (10), the current study was designed to define the utility of early restredistribution thallium201 imaging in detecting myocarThe goal of this study was to determine the prognostic utility of the exercise thallium201 stress test in ambulatory patients with chest pain who were also referred for cardiac catheterization Accordingly, 4 to 8 year (mean +/ 1SD, 46 +/ 26 years) followup data were obtained for all but one of 383 patients who underwent both exercise thallium201 stress testing and cardiac Prognostic utility of the exercise thallium201 test in The clinical utility of thallium201 myocardial perfusion imaging in aortic valve stenosis was evaluated at rest and after exercise in three groups of patients: (1) 20 normal subjects, (2) 11 patients with aortic valve stenosis and coronary artery disease (70 percent or greater narrowing of luminal diameter), 11 patients with aortic valve stenosis without coronary artery disease (30 percent or Thallium201 myocardial perfusion imaging in aortic valve

After a 4minute iv dipyridamole infusion, 014 mg/kg/min, serial thallium201 scans were obtained in 60 patients undergoing cardiac catheterization Forty patients had significant (> 50% stenosis) coronary artery disease (CAD), and 20 patients had normal coronary arteries or trivial lesions The images were graded qualitatively for thallium activity by three observersAlthough the combination of increased pulmonary thallium uptake and ischemia has demonstrated prognostic utility, the value of pulmonary uptake independent of ischemia has not been evaluated critically Accordingly, our purpose was to evaluate the prognostic utility of thallium lung uptake in patients who do not have stressinduced defects We studied 184 patients who were divided into three Prognostic utility of increased pulmonary thallium uptake The myocardial uptake of thallium201 is a sarcolemmal membrane Na/K ATPasedependent active process requiring cell membrane integrity, and is therefore indicative of myocardial viability Thallium201 uptake by myocytes is also a reflection of regional perfusion (required for delivery of tracer to the myocyte) and viabilityAssessment of myocardial viability by nuclear imaging in

Thallium201: An Agent for Myocardial Perfusion and
The clinical utility of thallium201 imaging depends to a great extent on its predictive value It should be remembered that a positive test result in a group with a high probability of disease pretest adds little to the diagnostic accuracy beyond that achieved by a proper clinical evaluation A negative test in a group with a low probability of disease pretest only confirms that pretest The prognostic utility of thallium imaging demonstrated in this study is analogous to observations from other studies showing the strong predictive value of thallium redistribution for future cardiac events after cardiac catheterization or uncomplicated myocardial infarctionSelection of patients for preoperative coronary Being a potassium analog, thallium can be used to detect myocardial cell membrane integrity via Na/K ATPase channels, where viable cells demonstrate delayed uptake as compared to resting imaging 10 Unlike thallium, technetiumbased SPECT does not demonstrate a delayed distribution 11 In the recent decades, thallium has rarely been used due to increase in ionizing NonInvasive Assessment of Myocardial Viability American
