老年性颈椎病的MRI诊断及表现

目的了解老年性颈椎病的ＭＲＩ表现在诊断方面的意义，并初步探讨一般病理过程。方法１００例老年性颈椎病均经用飞利蒲公司生产的０．５ＴＭＲＩ扫描系统，使用颈椎表面线圈行自旋回波及梯度回波序扫描。结果在１００例老年性颈椎病中，生理曲度发生改变占７８％；椎体骨质增生占椎体总数的６８％；间盘变性及间盘突出或膨出分别占间盘总数的５３％及４７％；后纵韧带骨化或肥厚占病例总数的１５％；椎体滑脱占病例总数的４％；而硬膜囊及脊髓受压占病例总数的１００％。结论ＭＲＩ能清楚显示颈椎病各部位的病变程度及病理变化。因此ＭＲＩ是诊断老年性颈椎病最理想的检查手段，对临床治疗及预后的判断具有重大意义。

MRI Findings and Diagnosis of Senile Cervical Spondylosis

Objective To study the MRI findings and their diagnostic significance in Senile Cervical Spondylosis(SCS), and to study the general pathology of the disease.Methods Philips 0.5 Tsuperconductive MRI made in Holland was adopted, cervical surface coil was applied to all of the 100 cases, sagittal and axle position were obtained by means of spin echo(SE) and gradient echo(FFE).Results The investigation included 100 cases of SCS, 78% showed signs of cervical curve changes, Hyperosteogeny was found in 68% of all vertebrae, Degeneration and protrusion rate were 53% and 47% respectively within the involved dises, 15% had posterior longitudinal ligament thickening or calcification, signs of spondylolisthesis could be found in 3% cases, All the patients showed compression of dural cavety of spinal cord.Conclusions MRI is ideal for the diagnose of SCS. For its high resolution, large scale of scanning and detailed imaging of position and extension of the pathology, MRI is valuable in treatment and prognosis of senile cervical spondylosis.
