[Interventional imaging: a new specialty in between radiology and surgery]. 
Interventional radiology can be defined as the medical field of all diagnostic and therapeutic procedures performed with imaging techniques (Sonography, angiography, X-scanner, Magnetic resonance, radionuclides ... ).  Interventional Radiology comprises 350 types-procedures in common use, that represent more than half a million acts/year in France.  Its development was promoted by all the innovations in imaging and by pioneers of Radiology who created new and adaptative tools in order to act as atraumatically as possible but specifically on the pathological process.  Interventional radiology needs practitioners who received a double education in imaging and medico-surgical specialty (before entering in an interventional imaging training).  To develop and evaluate the tools of tomorrow, Interventional Radiology needs to develop one or several research interfaces where interventional radiology, companies and searchers could meet and work altogether.
