The Value of Different Angle MPR Using Multi-slice Spiral CT in Diagnosing Lumbar Spondylolysis / 实用放射学杂志

ABSTRACT

Objective To study the value of different angle MPR using 64-slice CT in diagnosing spondylolysis.Methods The volume data of isotropic scanning in 50 cases of spondylolysis using 64-slice CT were post-processed by different angle MPR. Four scanning modes were imitated conventional intervertebral disc scanning mode, transverse scanning, oblique transverse scanning along the direction of vertebral arch, longitudinal and sagittal images of lumbar vertebrae. The detective rate of isthmus fissue, dislocation of disruption end, bone frature piece, false joint of above four methods were analysed. Results The sensitivity of detecting the isthmus fissue was highest by sagittal MPR and oblique transverse MPR images (100%)(u=8.51,P
