磁共振成像对腰椎疾患诊断的初步评价

MAGNETIC RESONANCE IMAGING IN DIAGNOSIS OF LUMBAR SPINAL DISEASES

报告腰椎疾患62例,包括椎间盘突出和椎管狭窄症。全部病例经后进路手术,施行椎间盘突出物摘除和神经根减压术。经手术证实,磁共振成像(MRI)诊断符合率为85.5％,其中椎间盘突出诊断符合率为90.4％,而椎管狭窄为81.1％。对MRI的认识和在腰椎疾患诊断评价作了讨论。作者认为MRI是一种精良的新技术,但也并非万能。为提高诊断符合率,必须提高对MRI的认识和检查技术水平。

Magnetic Resonace Imaging (MRI) is a new diagnostic procedure which may be used in the diagnosis of diseases of lumbar spine and its contents.This technique is noninvasive and does not use ionizing radiation.MRI has higher/resolution than CT scan,and myelograghy is obtained.A retrospective study of MRI of the lumbar spines in 62 patients with protrusion of lumbar disc and stenosis is presented in this paper.These cases ranged in age from 25 to 67 years,with a mean of 40.5 years.There were 40 men and 22 women.All patients were operated upon through postanter-ior approach with resection of the intervertebral disc and decompression for stenosis.The result of surgery demonstrated thar the rate of accuracy of MRI diagnosis was 85.5%.Among them,acorrect diagnosis of herniated lumbar disc was 90.4%,that of spinal stenosis 81.1%.
