Cardiac computed tomography (CT) is a robust technology for the noninvasive assessment of a spectrum of cardiovascular disease processes. The predominant use of cardiac CT is fi rst detection of atherosclerosis and subsequently detection of stenosis, perfusion imaging, wall motion and ultimately valve disease. Although the technology has been clinically available for more than 25 years, cardiologists and even radiologists are largely unaware of its full capabilities. This chapter reviews cardiac CT's current clinical uses and its potential for even greater utility in the near future. Advances in spatial and temporal resolution, electrocardiographic (ECG) triggering methodology, radiation dose reduction, and image reconstruction software have helped in the evaluation of coronary artery anatomy and vessel patency, providing the ability to noninvasively diagnose or rule out signifi cant epicardial CAD. Cardiac CT allows the 3-dimensional (3D) simultaneous imaging of additional cardiac structures-including the coronary veins, pulmonary veins, atria, ventricles, aorta, and thoracic arterial and venous structures-and defi nition of their spatial relationships for the comprehensive assessment of a variety of cardiovascular disease processes. This chapter details the role of cardiac CT for the assessment of cardiovascular pathology with an emphasis on the detection of coronary atherosclerosis.

“…With the conventional, x-ray computed tomography (CT), temporal resolution is inferior for the diagnosis of intracardiac shunts, and complicated morphological anomalies in newborns, infants, and children, even when using the electrocardiographic (ECG)-gating technique, are difficult to clarify because of the subjects' small size [4] .…”

The slip ring and nutate/rotate configuration of the new, fourth-generation, computed tomography (CT) (TCT-900S, Toshiba Medical Company) makes it possible to scan consecutively 25 slices every 75 s. This scanner also rapidly provides hemodynamic and multiplanar reconstruction images. Studies were performed on 13 children with various forms of complex congenital cardiovascular anomalies. The findings correlated very well with those by angiocardiography and echocardiography. But the cardiac valves were difficult to scan, and combined use with echocardiography was considered to be indispensable. The rapid multiplanar reconstruction imaging is very effective in depicting coarctation of the aortic isthmus, ductus arteriosus, and hypoplasia of the great arteries in newborns and infants who have small target regions. Cine-displays of such images can clearly show ventricular and atrial septal defects. This new CT system proved effective in diagnosing complex congenital cardiovascular anomalies even in young infants.

“…All patient subgroups with congenital and acquired heart disease can be effectively examined by cine-CT. Various forms of aortic disease, including aortic malpositions, dissections and true aneurysms are well suited for investigation by cine-CT and the diagnostic accuracy is similar to that of angiocardiography [20][21][22][23][24]. The ability of cine-CT to reconstruct projectional images esembling those of angiography in selected planes from contiguous axial scans provides a unique three-dimensional approach.…”

Ultrafast (Cine) CT scanning provides cross-sectional millisecond tomography, and therefore combines digital imaging and high resolution without the need for either cardiac catheterization or any form of ECG gating. Fifty millisecond multilevel scanning at rates of 17 scans per second allows quantitation of left ventricular (LV) function at each tomographic level during a cardiac cycle. Calculations of global and regional ejection fraction can be obtained, and in addition ultrafast CT also has the potential for providing unique data concerning regional wall thickening, mass and even regional myocardial perfusion. Interventional studies with exercise and pharmacological agents have commenced and are currently being evaluated.
