| 目的 通过测量骶髂关节面下骨髓T2值，探讨T2mapping对强直性脊柱炎早期骶髂关节病变的诊断价值。方法 收集我院36例初步诊断为强直性脊柱炎的患者为病例组,24例健康体检者为对照组，分别测量病例组骶髂关节面下病变区及周围相对正常区、对照组骶髂关节面下骨髓的T2值,采用两独立样本t检验对两组骶髂关节面下骨髓的T2值进行统计分析， 并采用配对t检验对病例组病变区及周围相对正常区骨髓的T2值进行分析。结果与对照组相比，病例组骶髂关节面下骨髓T2值明显升高，差异有统计学意义（P <0.01)。病例组中病变区比周围相对正常区骨髓T2值升高，差异有统计学意义（P <0.01)。结论T2mapping序列通过测量骨髓T2值的变化，可以更早的发现强直性脊柱炎患者早期骶髂关节的病变。 |

| Objective To determine the value of T2mapping of ankylosing spondylitis in the early diagnostic value of sacroiliac joint lesions. Methods 36 patients with ankylosing spondylitis by cases and 24 healthy controls were collected. The case group were measured sacroiliac joint lesions area and the surrounding relatively normal area, the control group were measured under the sacroiliac joint surface T2 values in the bone marrow, and statistical analysis. Results Compared with the control group，the cases of sacroiliac joint surface bone marrow T2 value increased significantly, the difference was statistically significant(P <0. 01 ). The mean of T2 value in the lesion area higher than the surrounding relatively normal area, the difference was statistically significant(P < 0, 01 ). Conclusion By measuring the changes of the bone marrow T2 values,T2mapping sequences could detect early sacroiliac joint lesions of ankylosing spondylitis patients. |
