Excerpt:
"Computed tomography (CT) is a technique
that can fully evaluate both cardiac structure and function. Recent
advances in imaging speed have allowed for more complete evaluation
of relatively stationary structures, such as the thoracic aorta,
and rapidly moving structures, such as the myocardium and coronary
arteries, providing the ability to noninvasively diagnose or rule
out significant epicardial coronary artery disease (CAD). When combined
with electrocardiographic (ECG) gating, freeze-frame images
of the heart can be obtained, obviating most of the blur caused
by motion artifact. This is particularly important in obtaining
contrast-enhanced images of the coronary arteries or quantifying
coronary artery calcium. These advances in spatial and temporal
resolution and image reconstruction software have also helped in
the evaluation of cardiac structures including coronary veins, pulmonary
veins, atria, ventricles, aorta, and thoracic arterial and venous
structures, with definition of their spatial relationships for the
comprehensive assessment of a variety of cardiovascular disease
processes. This chapter details the current and future role of cardiac
CT for the assessment of cardiovascular pathology...."
