Left ventricular function, myocardial perfusion and viability.

Cardiac computed tomography is now poised to revolutionize the practice of cardiology. Multi-detector row CT (MDCT) has the potential to evaluate cardiac function, myocardial perfusion, and viability. These capabilities, combined with the robust ability of MDCT to noninvasively image the coronary arteries, makes MDCT a comprehensive tool for the evaluation of coronary artery disease and its anatomic and physiologic impact on the myocardium. Recent technologic advances in MDCT technology in regards to detector coverage, and spatial and temporal resolution promise to improve the capabilities of cardiac CT in the assessment of cardiac function, perfusion, and viability.
