X ray lumbo sacral spine showing grade II L over S listhesis

The sagittal plane is best fordisplaying the abnormal anatomy ofspondylo-listhesis, T2-weighted imagesfor the canal and T1-weighted images forthe pars interarticularis and neuralforamina. The sagittal view clearlyshows the degree of subluxation and therelationship of the intervertebral disk tothe adjacent vertebral bodies and thespinal canal. Parasagittal images aregood for showing encroachment on theforamina by disk or hypertrophic bone. Loss of the normal fat signal cushioningthe nerve root is a sign for significantforaminal stenosis.

Posterior listhesis of a lumbar vertebra in spinal tuberculosis.

Symptomatic thoracic disks are uncommon, accounting for about 1% of alldisk herniations. The rib cage, small intervertebral disks, and coronalorientation of the facets joints all contribute to limited mobility of thethoracic spine, and consequently, a lower risk of disk herniation. The mostcommon level is T11-T12, where the spine is relatively less rigid. SagittalT2-weighted FSE sequences are excellent for displaying indentation of ventralthecal sac and impingement of the spinal cord by thoracic disks. Axial imageshelp delineate lateralization to either side. Disk morphology is similarto the cervical region. Calcification is more common in thoracic disk fragmentsand parent disks than in cervical or lumbar region.

Spondylolysis and spondylolisthesis occur in the lumbar spine

In the evaluation of degenerative spine disease, multiple anatomic sites need to be imaged,including the intervertebral disk, spinal canal, spinal cord, nerve roots, neuroforamina, facet joints,and the soft tissues within and surrounding the spine. Many pulse sequences are available, andspecific protocols vary among different MR sites. There is general agreement that the spine needsto be imaged in at least two planes, and surface coils are used almost exclusively. In the cervical andthoracic regions a T2-weighted sequence is mandatory to assess damage to the spinal cord. Thinsections are required to visualize the neuroforamina, and pulse sequences must be tailored tocounteract CSF flow and physiologic motion. The imaging requirements for the lumbar spine are lessstrenuous because the anatomical parts are larger. Most protocols include a T1-weighted sequenceand some type of T2-weighted sequence to give a myelographic effect. Fast spin-echo (FSE)techniques allow enormous time savings, and if available, they have replaced conventional spin-echofor T2-weighted imaging of the spine. Three-dimensional gradient-echo (GRE) methods can achieveslice thicknesses less than one millimeter, an advantage for displaying cervical neuroforamina.
