title: Sequences and techniques in spinal MR imaging.
abstract: The optimal protocol in spinal MR imaging is not evident. Sagittal T2 weighted FSE, sagittal T1 weighted SE and axial T2 weighted FSE sequences are widely accepted for imaging patients with sciatica and/or lumbar pain. Because of the limited amount of CSF compared to the lumbar spine, the choice of sequences is much more complex in the study of the cervical spine. Sagittal T2 FSE, sagittal T1 SE and axial 2D GE images are suggested in routine cervical spine imaging. To assess the bone marrow, a STIR sequence can be added to this protocol on both lumbar and cervical spine examinations. The 2D GE produces an acceptable image quality to differentiate between the disc and bony protrusions. The use of FLAIR for imaging spinal cord lesions remains controversial in the literature.
