Multidetector row computed tomography (MDCT) is a powerful noninvasive imaging tool with a number of advantages over previous computed tomography (CT) technology. The incorporation of multiple detector rows enables faster scanning and thinner collimation. As a result, the entire body can be imaged in a single breath hold with improved z-axis resolution. These improvements have also expanded the clinical applications of CT. MDCT is considered an acceptable alternative to conventional imaging techniques such as catheter angiography, intravenous urography, and barium enema. This article will provide an overview of MDCT technology and its use in the diagnosis of diseases affecting coronary and peripheral vasculature, head and neck, lungs, as well as the gastrointestinal and genitourinary tracts.
