摘要
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。
The role of radiography and magnetic resonance (MR ) imaging in the detection of sacroiliitis in patients with ankylosing spondylitis (AS) was compared in this study. Thirty six sacroiliac jolnts in 18 patients with AS were examined with radiography and MR scan. MR images were performed with the sequence of the coronal T1 weighted image, T2 weighted image, and T2 weighted image. Images of all patlents were graded according to the modified New York criteria. Statistical results showed that significant differences existed between MR imaging and radiography in the detection of sacroiliitis (P<0.01). MR imaging was superior to plain film radiographs in visualising erosions (P<0.01). Radiography cannot reveal the cartilage changes and bone marrow oedema, which can only be seen in MR images. In the absence of radiographic changes, MR imaging can provide objective and complementary find-ings of sacroiliitis in patients with AS. Due to the ability to image cartilage changes and bone marrow oedema directly, MR imaging may be particularly useful in early diagnosis of sacroiliitis. For patients without any changes on sacroiliac joint radiograph, further examina-tion of MR imaging may be advisable.
