A 3D T2/T1-weighted balanced-SSFP sequence has been developed to visualize the nerve roots inside the thoracolumbar spinal canal and their exit point from the spinal cord for clinical 3T MRI systems and coil setups. This sequence allows acquisition of large field-of-view, high resolution (sub-millimeter), almost isotropic images in less than 5 minutes. Furthermore, it is fully balanced, thus allowing high SNR, and intrinsically flow compensated. Hence, CSF flow artifacts are avoided. The acquired volumes in 15 volunteers showed good contrast between CSF, spinal cord and nerve roots (negative contrast), which could allow adequate visualization of intra-spinal pathologies.
