| 目的 探讨强直性脊柱炎(AS)骶髂关节软骨病变的MRI表现。方法 收集符合2009年ASAS分类标准的强直性脊柱炎患者30例(AS组),对患者行骨盆正位片和MR序列扫描(STIR、T1W SE、T2W SE、3D-WATS)。另选取20名健康志愿者作为对照组,行相同参数下的MR扫描,对比观察两组骶髂关节软骨表现,并测量对照组骶髂关节软骨厚度。结果 3D-WATS序列显示AS患者的骶髂关节软骨呈不规则增粗、扭曲、中断。该序列可分辨出正常骶侧软骨、髂侧软骨及两者之间的间隙。对照组骶侧软骨厚度[(1.38±0.17)mm]大于髂侧软骨厚度[(0.81±0.16)mm],差异有统计学意义(t=10.90,P<0.001)。结论 3D-WATS序列可显示骶髂关节软骨破坏,为早期诊断强直性脊柱炎提供影像学依据。 |

| Objective To investigate the MRI findings of sacroiliac joint cartilages changes in patients with ankylosing spondylitis (AS). Methods Thirty patients who were in line with 2009 ASAS classification standards of AS were enrolled. Anterioposterior radiogram and MR scans of pelvis were performed. MR sequences included STIR, T1W SE, T2W SE and three dimensional water selective (3D-WATS). Twenty healthy volunteers were selected as control group and underwent the same MR scan. MRI findings of sacroiliac joint cartilages were observed and compared between the two groups, and the thickness of sacroiliac joint cartilages in control group was measured as well. Results 3D-WATS sequence showed the irregular distortions and interrupt in sacroiliac joint cartilages of patients with AS. This sequence could discern cartilages of sacrace side and iliac side and the interspace between them in normal persons. The cartilages of sacrum ( mm) was thicker than that of ilium's ( mm) in healthy people (t=10.90, P<0.001). Conclusion MR 3D-WATS sequence can show the damage of sacroiliac joint cartilages and provide imaging evidence for early diagnosis of ankylosing spondylitis. |
