摘　　要：目的：研究多层螺旋 CT（MSCT）图像后处理技术对膝关节创伤的临床应用价值。方法回顾性分析75例膝关节创伤患者的 X 线片和 MSCT 检查的临床资料。结果75例膝关节创伤患者,X 线检查明确发现64例患者存在骨折,共有78处骨折,6例患者可能存在骨折,漏诊及误诊患者共5例,检出率为88.6%；所有患者经128层螺旋 CT 图像后处理技术———多平面重建（MPR）及容积再现（VR）技术明确诊断出75例膝关节骨折,共有88处骨折,检出率为100.0%,明显高于 X 线检查（χ2=6.1172,P 〈0.05）,以MPR 技术对膝关节骨折的检出率最高。结论MSCT 图像后处理技术可直接、清楚、全面地显示膝关节创伤情况,有助于了解骨折与周围软组织和关节腔的关系,以此制定准确合理的临床治疗计划。Objective To study clinical application value of 128-slice spiral CT imaging post-processing technique in knee joint trauma.Methods 75 cases of knee traumatic patients were examined by ordinary X-ray and 128-slice spiral CT imaging post-process-ing technique,and retrospectively analysed.Results For 75 cases of knee trauma patients,on X-ray examination 64 cases of fracture patients（78 fractures）,6 patients of possible fractures,5 cases of missed diagnosis and misdiagnosis in were found,the detection rate was 88.6%;all patients underwent 128-slice spiral CT imaging post-processing technique-MPR/VR,and definite diagnosis of knee joint bone fracture was found in 75 cases （88 fractures）,the detection rate was 100.0%,which was significantly higher than that on the X-ray examination （χ2 =6.1 1 7 2,P 〈0.05）.The MPR reconstruction of knee joint fracture is of the highest detection rate.Con-clusion MSCT imaging post-processing technique can directly,clearly and comprehensive display knee joint trauma cases,and help doctors understand the relationship between fractures,soft tissue and joint space,in order to develop accurate and reasonable clinical treatment plan.
