  • 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
