As a computer technique, the CT scan, recently induced great changes in both medical and radiological practice, photoelectronic detection of X-rays and digital image processing just begin to improve the angio-cardiography. The first generation of intravenous angiography systems is presently available. They allow to visualize the chambers of the heart as well as the great arteries using a fast intravenous injection of contrast medium. In the next future, this technique will probably be suitable for visualizing the entire vascular network, including small arteries and veins, and others cavities such as urinary and digestive tracts. In the long term, a large increase in computer assisted diagnosic techniques is likely to occur, as well as the suppression of the film support.
