Objective:
To review the utility of MR imaging in the assessment of renal masses, with special reference to the morphological characteristics of the different tumor types. Staging of renal cell carcinoma is also discussed.
Methods:
The literature on the use of MRI in the evaluation of renal masses is reviewed. The technical aspects and the indications of MR urography are discussed and compared with those of other imaging techniques.
Results/Conclusions:
MRI permits multiplanar analysis and facilitates detection and characterization of lesions. Furthermore, it allows clear depiction of the relationships of the tumor and the adjacent structures for efficient surgical planning.
