Three-dimensional volume rendering was also used to help diagnose patients.

Serial axial images, as well as the reconstructed multiplanar and maximum intensity projections, were used primarily for diagnostic purposes. Reconstructions of the raw data were performed using the Philips, as well as the TeraRecon (Tokyo, Japan) workstations. Usually, 75 mL of nonionic contrast media is injected at 5 mL/s through a large-bore, intravenous access in the antecubital fossa. 45-mm intervals with a tracking marker placed upon the descending thoracic aorta.
We retrospectively reviewed the 452 coronary patients who have undergone CTA since February in an outpatient setting. 1Ī Philips 64-slice CT scanner (Philips Medical Systems, Best, The Netherlands) was placed in our institution in February 2007. Variations that occur in less than 1% of the general population may be considered abnormal or anomalies. The information provided by the multislice CT scan provides useful information on the origin and course of the anomalous vessel and its relationship with the great vessels before surgical or eventual coronary intervention. The detection of anomalies of the coronary arteries is important in diagnosing and treating potentially dangerous variations. Limitations in resolution of the CT scanner (usually to 1-mm vessel size) reduce the number of vessels that are visible and the exact determination of the degree of stenosis, which would be greater on traditional angiographic studies. It has changed the diagnosis and management of all these cardiovascular systems. Multidetector high-speed computed tomography angiography (CTA) has been much heralded as a major diagnostic innovation of many cardiovascular systems, including the coronary and peripheral circulation.
