Recent advances in computed tomography have the potential to change the way imaging is performed in the detection of coronary artery disease. The current generation of scanners offers the ability to rapidly acquire thin sections in conjunction with the electrocardiogram, allowing for both anatomic and physiologic data to be obtained. These advancements hold the promise for a noninvasive means of directly evaluating the coronary arteries that can be applied in every day practice. This article reviews the advances in technology and their implications for imaging the heart.
