摘要 目的探讨多层螺旋CT(MSCT)三维(3D)重建技术在骶髂关节(Sacroiliacjoint,SIJ)穿刺活检与介入治疗的应用。方法确诊强直性脊柱炎(ankylosingspondylitis,AS)拟行SIJ穿刺患者17例共34个关节,于术前行薄层容积螺旋CT扫描,分别作曲面重建(c-MPR)、多平面重建(MPR)、容积再现技术(VRT)、表面遮盖显示(SSD)等三维重建后处理,并根据立体图像选择穿刺靶点。结果CT诊断Ⅰ级4例,Ⅱ级11例,Ⅲ级2例。34个SIJ穿刺均取得成功,手术时间短,17例均在40min内完成双侧SIJ的定位、穿刺、取材及关节内注射,术程顺利,对SIJ损伤小,未见并发症。结论MSCT三维重建在指导SIJ穿刺活检及介入治疗中有较高应用价值。
