摘要
目的比较64层螺旋CT与磁共振成像(MRI)对强直性脊柱炎(As)骶髂关节早期病变的诊断价值。方法回顾性分析64层螺旋CT诊断0一Ⅱ级骶髂关节炎并经临床证实的66例AS患者骶髂关节的MRI表现,其中6例MRI平扫加增强扫描。结果cT诊断0级骶髂关节炎15例,I级骶髂关节炎20例,Ⅱ级骶髂关节炎31例。MRI表现有关节旁骨髓水肿52例,关节软骨侵蚀48例,关节旁骨髓脂肪堆积36例,关节软骨下骨质侵蚀31例;6例MRI增强扫描表现为关节滑膜增厚和异常强化。结论MRI能发现多层螺旋CT不能显示的骨髓水肿和滑膜炎等急性炎性改变,早期诊断价值优于多层螺旋CT。
Objective To investigate the diagnostic value of 64-slice CT and MRI in detection of abnormal sacroiliac joint changes in patients with early stage of ankylosing spodylitis ( AS). Methods The 64-slice CT and MRI imaging data of the sacroiliac joint early diseases( grade 0 -Ⅱ lesion) for the 66 patients with clinical confirmed were reviewed retrospectively, of which MRI contrast enhanced was performed in 6 patients. Results CT showed grade zero lesion 15 cases,grade I lesion in 20 cases and grade Ⅱ lesion in 31 cases. MRI revealed bilateral articular bone marrow edema in 52 cases, articular cartilage erosive destruction in 48 cases, fat accumulation of bilateral articu- lar bone in 36 cases, articular bone erosive destruction in 31 cases. Bilateral synovial membrane enhancement was showed in all patients who underwent contrast enhanced. Conclusions MRI can detect acute inflammatory changes which can not display by MSCT. Compared with MSCT,MRI is more useful in detection of abnormal sacroiliac joint changes in patients with early stage of AS.
