摘要
目的:旨在评估强直性脊柱炎(AS)患者骶髂关节病变的CT表现,并比较X线和CT在强直性脊柱炎骶髂关节病变中的作用。材料和方法:对21例AS患者骶髂关节X线平片及CT表现进行回顾性分析。X线检查包括骶髂关节正位片,CT检查使用GE—H9800Quick型CT机及GE—HispeedCT/i型螺旋机,层厚5mm,间隔5mm。结果:21例中全部42个关节受累,主要病变包括:①关节面下囊性变。②关节面硬化。③关节面侵蚀。④关节间隙变窄或增宽。⑤关节强直。结论:CT对于强直性脊柱炎骶髂关节病变的检出率高于X线平片,尤其是对于AS骶髂关节早期病变及较小的病变的诊断优于X线平片,而对于中度及重度关节炎的改变同X线诊断价值相同。
Objective:To evaluate features of
sacroiliitis with ankylosing spodylitis on CT imaging and to compare the CT imagings with
findings obtaited by conventional rodiography with ankylosing spodylitis(AS).Material and
methods:Twenty one AS patients were analysed.each patient underwent CT and canventional
rediography scanning and his(her) CT imagings of vertebra column,Sacroiliac were compared
with those by radiography.Sacroiliitis was observed in all 21 AS patients.An anteroposterior
radiography of the pevis was performed on each patient.GE-9800 quick CT and Hispeed CT/i
equipments were used in CT imaging.Slice thickness and space was 5mm.Results:All 42 joints
in 21 AS patients were involved.Predominant abnormalities included:(1)cystic change under the
articular surface;(2)sclerosis of the articular surface;(3)erosions of the articular surface;(4)joint
space narrowing and widening;(5)joint ankylosis.Conclusion:CT and radiography are both
helpful to the diagnosis of AS.CT is surperior to plain radiograph .AS far as the middle and
serous inflammatory changes of joint,diagnostic value of the two is equivalent.
