Precordial scanning of the distribution of radioiodine (I¹³¹-labeled iodide) in patients with myocardial infarction has been suggested by others as a means of delineating the infarcted area.

Attempts to localize radioiodine in 14 precordial scans of 12 patients with myocardial infarction resulted in the demonstration of localized areas of radioactivity in seven scans. This collection of radioactivity was found to be within the stomach, resulting from the normal concentration of radioiodine that occurs in gastric secretions.
