[Focal lesions of the spleen: contribution of magnetic resonance imaging].

MR findings in the study of focal splenic pathology are discussed in this paper. MR examination of the spleen shows some technical limits in the diagnosis of masses affecting this organ. On the contrary, the introduction of new paramagnetic contrast agents, with organospecific affinity, will no doubt improve the diagnostic power of MR imaging, in order to gain more information about these diseases.
