Cardiovascular ultrafast computed tomographic angiography.

Ultrafast computed tomography can substitute for angiography and provide answers to clinical and therapeutic questions. Because of superior definition of vessels and myocardium, current applications include imaging the aorta, carotids, vena cava, and other venous structures, congenital and acquired pulmonary artery abnormalities, coronary arteries, coronary artery saphenous, and internal mammary artery bypass grafts, right and left ventricles, cardiac tumors and thrombi, cardiomyopathies (ischemic, dilated, hypertrophic, and restrictive), congenital heart disease, and a variety of other acquired abnormalities. Parallel contiguous tomographic levels provide excellent structural definition including inner vessel wall and endocardium.
