Abstract: Objective: To evaluate multi-slice spiral CT(MSCT) in lumbar-stop re-diagnosis of clinical value.Methods: GE's 16-slice spiral CT(Light speed 16) of 50 patients with clinical diagnosis of lumbar disc patients were routine lumbar CT scan and volume scan;in AW4.2 workstation will simulate the CT volume scans regular waist restructuring and one-stop re-scan the disc(including VR,MPR,CPR).The more conventional analog conventional lumbar disc lumbar disc scan and sweep and stop re-restructuring of the lumbar lordosis,lumbar vertebral hyperostosis,intervertebral joint abnormalities,bony spinal stenosis,abnormal transverse and transverse foramen,the vertebral space narrowing,lateral recess stenosis,vertebral Hsu nodules or damage,disc abnormalities,paraspinal soft tissue abnormalities,nerve root compression,the degree of spondylolisthesis,posterior longitudinal ligament and yellow ligament show signs of calcification and other related capabilities.Results: The posterior longitudinal ligament and yellow ligament calcification,nerve root compression,disc abnormalities,intervertebral joint abnormalities,lateral recess stenosis,paraspinal soft tissue abnormalities,abnormal transverse and transverse holes in the conventional analog conventional scan and lumbar disc lumbar disc restructuring and one-stop re-scan on the three good agreement,no significant difference(P>0.05);lumbar lordosis,lumbar vertebral bone hyperplasia,nodules or vertebral destruction Hsu,spondylolisthesis the degree of spinal stenosis in a routine bone scan and simulation of conventional lumbar disc lumbar disc scanning is also on the restructuring has good consistency,but there are significant differences and one-stop restructuring(P<0.05).Conclusion: MSCT volume scan can accurately show the reorganization of one-stop for more images of lumbar spine disease-related signs,for clinical diagnosis of more valuable image information,and reducing the inspection cost and radiation in patients with radiation damage.
