ABSTRACT:
A method of cardiac radiological examination for coronarography comprises the steps of:a) introducing contrast medium simultaneously in the left coronary artery and in the right coronary artery from the aortic root and, in parallel,b) acquiring a sequence of dynamic images of the propagation of the contrast medium in the left and right coronary arteries with a displacement of the image plane, during the acquisition of said images, along a determined trajectory (E28). The contrast medium can be introduced in a cyclic manner during the acquisition of dynamic images, each cycle of introduction corresponding to a phase of closure of the aortic valve in the cardiac rhythm. 3D and 4D images with optimal efficiency can be obtained in the use of contrast medium. An injection device for producing the above cycles is synchronized with the introduction of the contrast medium.
