May support noninvasive localization of MI and ischemia; leaves open prospective validation before clinical use.
Does intravenously administered radioactive potassium (43K) myocardial perfusion imaging accurately delineate areas of myocardial infarction and transient ischemia in patients with coronary artery disease?
Radioactive potassium (43K) myocardial imaging provides a safe, noninvasive method to assess regional myocardial perfusion and identify ischemia or infarction.
Zaret et al. (1973) studied this question.
