[Future perspectives in medical imaging].

Medical imaging, less than 105 years after the invention of X-rays in medicine, shows signs of extraordinary and almost exponential rise. Among the new techniques, the stress is laid on the last developments of echography like the imaging in three dimensions or the harmonic imaging. The helical scanner currently allows imaging in real time, from incredibly short times of acquisition and launches out in the virtual endoscopy. The MRI and particularly angio MR allows the visualization of small arterial or venous malformations as for soon the study of the coronary vessels with a reliability which will compete with the coronarography. The diagnostic angiography is undoubtedly destined for disappearing as of many other techniques which will be one day obsolete, or superfluous compared with such relevant and less invasive methods.
