MR staging of prostate cancer. How we can improve our accuracy with decisions aids and optimal techniques.

This article reviews the MR staging of prostate cancer. There has been considerable variability in the MR results to date. The reasons are complex and include reader experience, the learning curve, and a lack of clear definition of the diagnostic features of advanced disease. The problems associated with achieving a consistently high degree of accuracy are discussed. The author describes a new study aimed at improving radiologists accuracy and illustrates some of the findings and specific features of advanced disease that are useful.
