In pelvic pain syndromes, selective nerve infiltration with a local anesthetic is used to test the hypothesis that a particular nerve is the source of pain. Diagnostic blocks require highest accuracy because they are typically used as a tool to help to make advanced management decisions such as surgery. MR neurography-guided injection procedures can increase accuracy especially in deeply situated and complex targets by the direct MR visualization of the nerve and the injectant.
