Angio-CT: heart and coronary arteries.
Despite a multitude of different medical and interventional strategies to treat coronary artery disease (CAD), the natural course of CAD is a relentless progression. The current gold-standard to assess the degree of stenosis is coronary angiography. In Germany alone, the total number of angiographic procedures rose by 45% from 1995 to 2000, while the fraction of interventional procedures remained almost constantly low at about 30% [Z. Kardiol. 90 (2001) 665]. Although coronary angiography has become a safe procedure with only a small risk associated, the inconvenience for the patient as well as the economic burden have fueled the quest to find an alternative, non-invasive method to visualize and assess coronary arteries. The following article will explore the application of computed tomography (CT) coronary angiography for detection of stenoses, and the issue of imaging of non-calcified and unstable plaques with MDCT.
