[Penile nuclear magnetic resonance (NMR)].

Nuclear Magnetic Resonance (NMR) is a new diagnostic technique with great opportunities of application in the field of the penile pathologies. A new interest for this diagnostic technique was born when the use of vasoactive agents, like papaverine or PGE1, and the use of para-magnetic contrast agents, like gadolinium, were introduced. The introduction of dynamic NMR in andrology allowed a better definition of anatomical details and a better knowledge of penile micro-circulation. N.M.R. is showing a great diffusion, because of a little invasiveness (X-rays are not used in this technique). The Authors show a wide spread of possible applications of NMR in penile pathologies, helping in the interpretation of the images. In conclusion the authors describe NMR as a diagnostic technique with great possibilities of improvement, even if the high costs don't allow a better diffusion until now.
