<prompt> Which of the following tests is used to detect reversible myocardial ischemiaAngiographyThallium scanMUGAResting Echocardiography  <response>: Answer is B Thallium scan Reversible Myocardial Ischemia can be detected by myocardial perfusion imaging using compounds labeled with thallium- 201 Thallium Scan What is Reversible Myocardial Ischemia: Role of Thallium scanning Reversible myocardial ischemia refers to areas of myocardium that become ischemic on stress exercise, but region bility circulation on resting and do not progress to infarction Such areas of myocardium can be detected by myocardial perfusion imaging using the Thallium scan. Thallium scan can thus help in distinguishing between on ischemic area reversible and an infracted scarred area of myocardium irreversible
