OBJECTIVE: To explore the features of obturator nerve (ON) by high-resolution CT (HRCT) at the same slice with multiplanar planar reconstruction techniques and clinic value thereof.
METHODS: The normal lumbar vertebral bodies of 60 healthy adults and the abnormal lumbar vertebral bodies of 31 patients with ON disorders were scanned with 16-slice spiral CT, multiplanar reconstruction was conducted in the Workstation ADW4. 1, with UNIX system and DICOM form. The images at the same slice were studied.
RESULTS: The shapes, thickness, direction, length, adjourning relationship, and tension could be shown at the same slice of oblique and coronal section or oblique and sagittal plane with rotation in external sides on the way from the starting point of dural sac to foramen obturatum in pelvis, meanwhile the manifestations of abnormal ON also could be shown.
CONCLUSION: The anatomical features and abnormal manifestation of ON at the same slice with 16-slice spiral CT using the multiplanar reconstruction techniques can be fully shown from the starting point of dural sac to the foramen obturatum in pelvis. This technique is very important in diagnosis and treatment of diseases of obturator nerve.
