Which of the following tests is used to detect reversible myocardial ischemia

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)
