Union pour le Développement de la Radiologie Interventionnelle (UDRI)
Non-profit association (law 1901), SIRET: 389 270 489 00021

Founded in 2003 by Drs Didier Bonnel and François Cornud, the UDRI aims to promote abdominal interventional radiology and prostate imaging.
In 2019, the association plans to develop interventional MRI to guide biopsy and treatment of abdominal-pelvic tumors using a three-dimensional guidance software and interstitial laser ablation.
For the prostate, the biopsy and focal treatment of some cancers are assisted by a compatible MRI robot (Figures 1 and 2) to shorten the biopsy time and increase its accuracy. Focal treatment spares the healthy tissue adjacent to the tumor, protecting the patient from side effects (sexual impotence, urinary incontinence) that can be observed after radical treatment. Under MRI guidance, the thermo-ablation (Figure 2) is controlled by a specific MRI sequence (Proton Resonance Frequency, PRF) that calculates in real time the temperature released by the laser fiber to destroy the tumor and preserve adjacent healthy tissues.
The association is participating in a multicenter study to demonstrate the safety and efficacy of MRI-guided focal laser ablation of cancer.
