Multidetector row computed tomography (MDCT) is an effective imaging technology, providing rapid and non-invasive images in three dimensions. Compared with standard computed tomography (CT), MDCT allows faster data acquisition and shorter scan times, with wider coverage, high resolution and the potential for cardiac gating. Routine thin-section acquisition allows for flexible reconstruction (thick or thin slices), while dedicated software provides three-dimensional and functional data analysis. The technology has a wide range of applications, particularly in cardiovascular medicine, where CT angiography has replaced conventional angiography in many regions of the body. Motion artefacts on cardiac scans are significantly reduced, and the diagnosis of luminal obstructive disease is enhanced. For non-cardiac applications, MDCT allows imaging of extensive arterial territories with unprecedented volumetric resolution. The detection of pulmonary emboli, characterization of arterial aneurysms and presurgical mapping are all improved substantially with MDCT. Pulmonary parenchymal imaging is enhanced, including superior lung nodule detection and better airway assessments. MDCT has rendered some diagnostic techniques, such as intravenous urography, virtually obsolete. The development of MDCT continues, with promises of further improvements and enhancements.
