퇴행성 경추질환의 MRI 및 임상소견 분석

Abstract

We undertook a retrospective analysis of 30 patients admitted to the Department of Neurosurgery Dongsan Medical Center Keimyung University utilizing Magnetic Resonanace Imaging (MRI) to make diagnosis and surgical indication of degenerative cervical spine lesions. All patients were taken T1 Weighted Image(T1W1) T2 Weighted Image (T2WI) and gradient echo image on 2.0 Tesla unit Pre- and postoperative MRI were obtained seven of 15 cases with myelopathy. All patients could be evaluated the extent and degree of disc herniation, osteophytes and cord compression. A focal area of High-Signal-Intensity (HSI) was observed on T2WI in 15 patients with myelopathy predominantly. HSI diminished postoperatively in the patients who improved clinically and remained the same in on case whose condition remained unchanged after decompression. We think MRI with high resolution images in the initial procedure of choice in decision-making of patients with degenerative cervical spine lesion. Furthermore HSI of the spinal cord produced by compressive lesions appears to be an important indicator for predicting prognosis of patients with myelopathy.

계명의대 동산의료원 신경외과에 1990년 5월부터 1991년 4월가지 1년간 MRI검사 후 퇴행성 경추질환으로 입원한 30명의 MRI 소견, 임상소견 및 수술 소견을 분석하여 요약하면, 1) MRI 소견상 척수압박정도와 임상 증상의 정도와 상호 밀접한 연관성이 있었을 뿐 아니라 MRI 추적검사로써 수술전후 임상소견의 예측에 도움이 되었다. 2) T2WI에 보이는 척수내 국소 HSI은 심한 척수압박과 척수병증을 보이는 환자애서 호발되었다. 3) 그러므로 MRI는 퇴행성 경추질환의 진단과 수술의 decision-making에 우선적으로 이용될 수 있는 진단방법으로 생각되며 척수내 국소 HSI 소견은 좋은 예후 판정인자로 생각된다.
