Actual contact surface between the extraforaminal nerve root and the adjacent structures is commonly missing on the conventional MR scanning, possibly leading to misdiagnosis. In our study, the detection rate of nerve root compression was significantly higher on the 3D-FIESTA-C images than T2WI. The shortest distance between the extraforaminal nerve root and the disc of L4/5 and L5/S1 in the healthy group was significantly longer than that in the lumbar disc herniation (LDH) group. The spatial relationship between nerve roots and surrounding tissues could be better described using 3D-FIESTA-C sequence and was helpful for the detection of nerve root compression.
