New trends in non-invasive coronary angiography with multislice CT.

Recent trends in computed tomography (CT) scanner technology has opened new frontiers in the field of non-invasive coronary angiography. Given the relatively important number of negative invasive angiographies performed each year, eliminating the risks inherent to this procedure by non-invasive methods greatly contribute to diminishing the risk. After injection of contrast, the procedure is performed under short apnea and triggered by electrocardiographic (ECG) recording that provides a multitude of possible image reconstructions; ie, volume rendering, virtual angioscopy, and three-dimensional (3D) reconstruction of the heart and coronary vessels.
