摘　　要：目的:分析早期强直性脊柱炎骶髂关节病变的CT及MRI表现,评价320排CT容积扫描结合MRI对早期强直性脊柱炎的诊断价值。方法:对60例临床拟诊为强直性脊柱炎的患者行骶髂关节320排CT容积扫描,其中10例CT可疑病例行MR检查。回顾分析60例患者的骶髂关节特征性改变,归纳早期强直性脊柱炎骶髂关节病变的影像学特点。结果:320排CT容积扫描能清晰显示骶髂关节微细骨质结构改变,MRI能清晰显示骶髂关节软骨、滑膜、骨髓等异常改变。结论:320排CT容积扫描结合MRI对早期强直性脊柱炎骶髂关节病变的诊断有较高的临床应用价值。Objective To study CT and MRI features of the sacroiliac joint lesion in the patients with early ankylosing spondylitis（AS） and evaluate the value of combined 320-row CT volume scanning and MRI for early AS. Methods Sixty patients suspected with AS underwent 320-row CT volume scanning for sacroiliac joint, of which, 10 ones diagnosed with AS by CT went through MRI examination. The changes of the sacroiliac joints of the 60 ones were analyzed retrospectively, and the imaging features of the sacroiliac joints of early AS were summarized. Results It＇s proved that 320-row CT volume scanning could display the minimal changes of bone structure and MRI gained its advantages for the examination of articular cartilage, synovial membrane and bone marrow. Conclusion The combined 320-row CT volume scanning and MRI are of great clinical value for the sacroiliac joint lesion of early AS.
