Computed tomography angiography for the diagnosis and management of coronary artery disease
Multidetector computed tomography angiographyb (MDCTA) combines the use of x-rays with advanced computerised analysis for the non-invasive visualisation of coronary arteries. The use of multiple rows of detectors enables up to 64 thin image slices to be obtained simultaneously. MDCTA is capable of 3D imaging the whole heart in less than 10 seconds with submillimetre isotropic resolution. Its main use is in detecting or excluding significant coronary stenoses (50% diameter reduction) in coronary arteries.
