摘要
目的:探讨强直性脊柱炎(AS)之骶髂关节病变的HRCT表现特点,以提高诊断与鉴别诊断水平。材料与方法:通过对121例AS患者(研究组)和50例正常体检者(对照组)双侧骶髂关节在常规扫描的基础上加扫HRCT扫描技术,HRCT技术采用高分辨率骨算法重建,层厚1.25mm,间隔1.2mm,对所有骶髂关节的HRCT表现特点进行分析。结果:AS骶髂关节HRCT表现特点为病变主要累及骶髂关节滑膜部的髂骨侧,常见关节软骨钙化、关节间隙改变,关节面毛糙,关节面下硬化或吸收等改变。结论:HRCT扫描技术对骶髂关节检查有利于AS早期诊断。
Purpose: Discuss ankylosing spondylitis (AS) the sacroiliac joint lesions HRCT performance characteris- tics, in order to improve the level of diagnosis and differential diagnosis. Materials and Methods: through the 121 cases AS patients (group) and cases of normal medical person (control group) double side sacroiliac joint on the basis of conventional scanning and sweep HRCT scanning technology, HRCT technique using high resolution bone reconstruction algorithm, layer thickness of 1.25 nun, interval 1.2 mm, for all sacroiliac joint of HRCT performance characteristics are analyzed. Results: AS sacroiliac joint HRCT performance characteristics for lesions nlajor involvement sacroiliac joint synovial department of the ilium side, common articular cartilage calcification, joint gap change, articular surface coarse, articular surface hardening or change the absorption. Conclusion: HRCT scanning technology to sacroiliac joint inspection to AS early diagnosis.
