Multiparametric MRI for Diagnosing Small Renal Tumors

The main objective of the study is to assess the diagnostic accuracy of mpMRI in small renal tumors. The study characteristics will comply with recommended methods (Quadas, Stard). The population to be included will be representative of patients who would benefit from mpMRI if it is demonstrated to be accurate. In this project, the MR protocol will used the conventional MR sequences either on 1.5 or 3T systems and do not require development. Each center may use their own protocol as long as it includes the mandatory sequences.
