摘　　要：目的探讨利用MRI测量10岁～20岁健康志愿者骶髂关节软骨厚度,更确切了解正常骶髂软骨,为骶髂关节病变早期诊断和动态观察提供依据。方法随机选择30例10岁～20岁健康志愿者及一具20岁女性尸体,行MRI3D-WATS斜冠状面扫描,测量骶髂关节软骨的总厚度及骶侧、髂侧软骨的厚度;尸体标本选择与MRI图象相对应的骶髂关节层面切开,取骶髂关节滑膜部一块,光镜观察。结果3D-WATS序列可分辨骶侧软骨、髂侧软骨及两者之间的间隙。相关分析表明,年龄与骶髂关节软骨厚度呈负相关,骶侧软骨厚度较髂侧软骨厚。结论10岁～20岁健康志愿者的骶髂关节软骨厚度随年龄增长,有逐渐变薄的趋势。Objective To investigate the thickness of SIJ cartilage of 10 to 20 years old healthy volunteers,which were measured with MRI.Methods Thirty healthy volunteers and one female cadaver of 20 years old were taken MRI.SIJ were visualized at oblique coronal MR imaging.Scan sequence used 3D-WATS.The total thickness of SIJ cartilage,the cartilage of iliac side and the cartilage of sacral were measured.The selected slice of SIJ of the cadaver which were corresponded to MR imaging were cut.Pathological specimens were ob-served under light microscope.Results 3D-WATS could distinguish the cartilage of iliac side,the cartilage of sacral and the space between the two sides.Correlation analysis showed negative correlation between age and the thickness of SIJ cartilage The cartilage of the sacral side is thicker than the cartilage of the iliac side.Conclusion The thickness of SIJ cartilage of 10 to 20 years old healthy volunteers have a trend that the carti-lage become thin with the age.
