The purpose of this chapter is to summarize available information regarding the pathophysiological basis for the scintigraphic detection of ischemic and infarcted myocardium. Two general approaches have been developed: (1) negative ('cold spot') imaging with agents which concentrate in normal myocardium, and (2) positive ('hot spot') imaging with agents which concentrate in acutely infarcted myocardium. These two techniques for the detection of myocardial lesions are complimented by scintigraphic techniques which evaluate ventricular function and wall motion with agents which label the cardiac blood pool.
