多层螺旋CT 3D技术在肩胛骨骨折诊断中的应用

Clinical value of SSD and MPR technique with multislicespiral CT in scapula fracture

目的:探讨多层螺旋CT(MSCT)表面遮盖(SSD)和多平面重组(MPR)在肩胛骨骨折诊断中的应用价值。方法:45例肩胛骨折患者,均行多层螺旋CT扫描,并行MPR和SSD重建成像,回顾分析其CT影像学资料,并与DR片进行比较。结果:45例患者中MPR发现骨折52处,合并肩关节脱位6例,其中DR漏诊骨折5处,CT常规轴位图像漏诊骨折3处,SSD重建漏诊骨折3处。MPR能良好显示微小骨折,SSD在显示骨折的位置、形态、范围及移位方面较好,SSD和MPR结合使用能清晰、全面地显示肩胛骨骨折的部位和程度。结论:多层螺旋CT的SSD和MPR成像技术,对肩胛骨骨折的诊断和手术方案制订具有重要临床价值。

Objective To sutdy the value of SSD and MPR Technique with multislicespiral CT in scapula fracture.Methods The imaging data of 45 fracture cases which had been received multislicespiral CT scanning and SSD and MPR reconstructive were retrospectively analysed. The results were compared with DR.Results In 45 cases,MPR found 52 scapula fractures,6 cases complicated with shoulder joint dislocations,5 cases missed diagnoses in DR,3 cases missed diagnoses in CT axial images,3 cases missed diagnoses in SSD.MPR were better than the others modalities innding the tiny fracture lines of scapular fractures,SSD were better in showing the position,region,range,shift of scapular fractures,m ultislicespiral CT can clearly and comprehensively demonstrate the features of scapula fracture by combination use of MPR and SSD.Conclusion The SSD and MPR technique of multislicespiral CT has very important value in the diagnosis and treatment of the scapula fracture.
