Infarct avid (hot spot) myocardial scintigraphy.

Infarct avid scintigraphy has emerged as a noninvasive method for determining the presence, location, and extent of myocardial necrosis secondary to infarction. In the future, it may replace studies such as serum enzyme tests, electrocardiography, and vector cardiography, all of which provide only indirect evidence of these parameters.
