本研究拟评估传统X线和MR成像技术对强直性脊柱炎患者骶髂关节炎的诊断作用。18例强直性脊柱炎患者的36个骶髂关节分别在一周内行X线和MR成像检查，对各影像按照修订的纽约标准进行分级评估，统计表明MR影像在骶髂关节炎诊断上明显优于传统X线检查，MR影像不仅在观察骨侵蚀方面优于X线检查，且可显示软骨改变及骨髓炎性水肿等征象，可作为X线检查的补充手段，有助于骶髂关节炎的早期诊断。
This study was to evaluate the diagnostic value of conventional X-ray and MR imaging for sacroiliitis in patients with ankylosing spondylitis. Thirty-six sacroiliac joints from 18 patients with ankylosing spondylitis underwent X-ray and MR imaging within a week respectively. The images were graded according to revised New York standards. The statistics showed that MR images were superior to those of sacroiliitis in diagnosis Traditional X-ray examination, MR imaging is not only better than the X-ray examination in the observation of bone erosion, and can show signs of cartilage changes and osteomyelitis edema, as a supplementary means of X-ray examination, contribute to the early stage of sacroiliac arthritis diagnosis.
