摘要
目的 探讨骶髂关节 (SIJ)炎磁共振 (MRI)检查的意义。方法 强直性脊柱炎 (AS)12例 ,未分化脊柱关节病 (uSpA) 7例 ,作X线平片、CT和MRI检查。其中 14例作动态MRI增强 ,11例作CT导引经皮穿刺活检。 8例正常志愿者作MRI平扫和动态MRI增强。结果 CT和MRI对Ⅲ、Ⅳ级SIJ炎的判断基本一致 ,对 0～Ⅱ级的判断二者相差较大。SIJ关节区的强化与组织炎症细胞的检出相关。关节旁骨髓水肿仅见于SIJ炎 ,也与SIJ的强化及组织炎症相关。结论 MRI通过增强 (动态 )、关节旁水肿等表现 ,推断Ⅱ、Ⅲ级SIJ的炎性活动程度 ,明确 0级、Ⅰ级SIJ炎的诊断 ,了解Ⅳ级SIJ是否存在炎症活动 ,对SIJ炎的早期诊断和病情活动性判定有重要意义。
Objective To evaluate magnetic resonance imaging (MRI) in the detection of sacroiliitis.Methods Twelve patients of ankylosing spondylitis (AS) and 7 undifferentiated spondyloarthropathies (uSpA) studied with the conventional radiography,CT,and MRI wthin a week.Of them,14 patients recieved dynamic magnetic resonance imaging (DMRI),11 patients received CT guided percutaneous biopsy.8 volunteers were examinated with pre contrast MRI and DMRI as the control group.Results The MRI diagnosis was accordant with CT for grade Ⅲ and Ⅳ sacroiliitis.But it was not for grade 0～Ⅱ.The DMRI in sacroiliac joint (SIJ) was correlated to the inflammatory cell infiltration.DMRI was also correlated with the bone marrow edema near the SIJ which only found in the patient.Conclusion Through DMRI and detection of SIJ bone marrow edema,MRI examination can estimate the degree of inflammation in grade Ⅱ and Ⅲ sacroiliitis,difinite the diagnosis of grade 0 and Ⅰ,and show the existance of inflammation in grade Ⅳ.
