[Features of obturator nerve by high-resolution CT at the same slice with multiplanar planar reconstruction techniques and clinic value thereof].

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.

[Value of multiplanar reconstruction of lumbar nerve roots on the same level by high resolution computed tomography in diagnosis of lumbar disc herniation and/or bulge].

Objective: To explore value of multiplanar reconstruction of lumbar nerve roots on the same level by high resolution computed tomography (HRCT) in diagnosis of lumbar disc herniation and/or bulge (LDHB).

Methods: Thirty-one patients with manifestations of typical nerve root compression, such as lumbago and tenderness of percussion pain at the corresponding sites were scanned with 16-slice spiral CT and multiplanar reconstruction of lumbar nerve roots on the same level with the workshop ADW4.150, and were diagnosed as with LDHB with 50 segments.
