CT Coronary Angiography

摘要: Non-invasive CT angiography of the coronary arteries is a challenging and rapidly advancing technique. Electron beam tomography initially permitted non-invasive visualization detection stenoses. Multidetector provides very high spatial resolution allows for excellent arteries. Hemodynamically significant stenoses can be detected excluded with accuracy. Current limitations include gantry rotation speed, arrhythmias, presence severe calcification. Continued technical progress expected to overcome some these limitations. The most likely beneficial clinical application use will rule out relevant artery in symptomatic patients low-to-intermediate likelihood Sufficiently large outcome studies ultimately have define applications compare CTA traditional diagnostic methods.
