CT Examination of the Coronary Arteries
This chapter reviews the techniques needed to obtain high-quality diagnostic images of the coronary arteries by means of CT angiography (CTA). The choice of imaging equipment, discussed in the previous chapter, involves the radiologist only once, at the moment that the CT equipment is purchased. By contrast, the choice of the optimal procedure for imaging of the coronary arteries involves the radiologist or technician in each exam, as the utmost care must be taken to always obtain images of optimal quality. It should be pointed out that this goal is unique for the coronary arteries, since in CT evaluation of the chest, abdomen, musculoskeletal system, or other static organs, suboptimal image quality may nonetheless allow a clinical diagnosis whereas for the coronary arteries the presence of movement artifacts may completely invalidate the diagnostic value of the examination.
