MSCT一站式重组在腰椎病诊断中的应用价值

目的:探讨多排螺旋CT(MSCT)一站式重组在腰椎病诊断中的临床应用价值。方法:采用GE公司16排螺旋CT(Light speed 16)对50例临床拟诊为腰椎病患者,分别行常规腰椎间盘扫描和CT容积扫描;在AW4.2工作站上将CT容积扫描图像进行模拟常规腰椎间盘扫描重组及一站式重组(包括VR、MPR)。对常规腰椎间盘扫描、模拟常规腰椎间盘扫描重组及一站式重组在腰椎生理曲度、腰椎椎体骨质增生、椎间关节异常、骨性椎管狭窄、横突及横突孔异常、椎间隙变窄、侧隐窝狭窄、椎体许莫氏结节或破坏、椎间盘异常、椎旁软组织异常、神经根受压、腰椎滑脱程度或类型、前后纵韧带及黄韧带钙化等相关征象的显示情况进行对比。结果:前后纵韧带及黄韧带钙化、神经根受压、椎间盘异常、侧隐窝狭窄、椎旁软组织异常、横突及横突孔异常在常规腰椎间盘扫描,模拟常规腰椎间盘扫描重组,一站式重组上三者具有较好的一致性,无统计学差异(P>0.05);腰椎生理曲度、椎间关节异常、腰椎椎体骨质增生、椎体许莫氏结节或破坏、腰椎滑脱程度或类型、腰椎间隙变窄、骨性椎管狭窄在常规腰椎间盘扫描和模拟常规腰椎间盘扫描重组上亦具有较好的一致性,但和一站式重组有统计学差异(P<0.05)。结论:MSCT容积扫描一站式重组能够准确地显示更多的腰椎疾病相关的影像征象,为临床诊断提供了更有价值的影像信息,并且降低了患者的检查费用及放射辐射损伤。

MSCT One-stop Recombination in Lumbar Disease Diagnosis Application Value

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.
