This new technology provides a noninvasive method to directly visualize the coronary arteries. Using a small dose of contrast, 64-slice CT angiography provides previously unobtainable visualization of the coronary arteries. Faster scanning also significantly increases patient comfort.
The new 64-slice multidetector CT scanner allows physicians to analyze coronary artery lesions and blockages that were previously impossible to visualize adequately.
CT continuously gathers multiple images, thus acquiring a greater amount of diagnostic information in less time. Unlike traditional x-ray imaging that produces a two-dimensional projection, CT takes thin x-ray scans, or slices, from multiple directions.
The multiple scans can be combined to form a 3-D image “set,” or volume. CT is used for 3-D volume imaging of the heart.
