As an alternative procedure to the exercise stress test used in myocardial scanning, vasoactive drugs were employed to elicit deficits in blood flow to myocardial regions supplied by stenotic arteries which maintain normal resting flow or collateral

To improve the sensitivity and accuracy of the detection of coronary artery disease with potassium-43 imaging at rest, a rapid serial scanning technique was developed to detect appearance time and sequence of myocardial isotope accumulation. The grou
