ABSTRACT
PURPOSE:
To evaluate prospectively the unoperated lumbosacral spine by gadolinium-enhanced MR for evidence of clinically correlative abnormal enhancement of nerve roots.METHODS:
Two hundred patients were prospectively studied with intravenous gadolinium- (0.1 mmol/kg) enhanced MR. Evidence was sought of intrathecal enhancement of lumbosacral nerve root(s), and the correlation of this enhancement with the clinical syndrome was evaluated.RESULTS:
Ten patients demonstrated abnormally enhancing lumbosacral nerve root(s) (5%). Of these, seven (70%) were associated with focally protruding disk pathology. The three (30%) remaining patients had isolated enhancement of multiple nerve roots in the absence of significant associated anatomic pathology. Overall, the correlation of radicular enhancement with the presenting clinical syndrome was excellent.CONCLUSION:
A breakdown in the blood-nerve barrier as observed on gadolinium-enhanced MR serves as a marker for nerve root pathology in the unoperated lumbosacral spine, which may have clinical relevance in certain clinical situations.
