title: MDCT of variations and anomalies of the neural arch and its processes: part 1--pedicles, pars interarticularis, laminae, and spinous process.
abstract: OBJECTIVE
  The purpose of this pictorial essay is to review the anatomic variations and congenital anomalies of the neural arch and its processes as seen on MDCT images of the spine.
  
  
  CONCLUSIONS
  Variations and anomalies of the pedicles, pars interarticularis, laminae, and spinous processes may be readily identified on MDCT studies. Familiarity with their MDCT appearances is required for characterization and differential diagnosis and may help assess their potential clinical relevance.
