A population-based cohort study of spinal diseases using MRI

这项研究是为了阐明日本男性和女性人群中使用MRI的脊柱疾病的流行病学证据。1011名参与者(335名男性和676名女性，平均年龄66.3岁)参加了调查。参与者完成了一份由面试者管理的问卷，并进行了人体测量和身体表现评估。检查颈椎、胸椎和腰椎的X线片和MRI。在1011名参与者中，那些拥有MRI敏感植入设备和其他取消资格的人被排除在外。在研究人群中，MRI上颈髓受压的患病率为24.4%，腰椎管狭窄症的患病率为9.3%。根据这些数据，日本估计有1470万人患有颈髓压迫，580万人患有腰椎管狭窄症。

This study was investigated to elucidate epidemiologic evidence of spinal diseases using MRI in population-based cohorts of Japanese men and women. 1,011 participants (335 men and 676 women, mean 66.3 years) were enrolled. Participants completed an interviewer-administered questionnaire and underwent anthropometric measurements and assessments of physical performance. Radiograph and MRI of cervical, thoracic and lumbar spine were examined. Among 1,011 participants, those who had MRI-sensitive implanted devices and other disqualifiers were excluded. Prevalence of cervical spinal cord compression on MRI was 24.4% and that of lumbar spinal stenosis was 9.3% in the study population. Based on these data, 14.7 million were estimated to have cervical spinal cord compression and 5.8 million were estimated to have lumbar spinal stenosis in Japan.
