摘　　要：目的探讨多层螺旋CT的多平面重建(MPR)、表面遮盖法(SSD)、容积再现技术(VRT)在肋骨骨折中的临床应用价值。方法收集2017年6月至2018年6月我院收治的疑似肋骨骨折患者800例,均接受X线和多层螺旋CT检查,进行MPR、SSD、VRT图像后处理,观察几种图像对肋骨骨折的显示效果。结果 MPR检出移位骨折887处,未移位骨折274处,肋软骨骨折91处;SSD检出移位骨折841处,未移位骨折261处,肋软骨骨折87处;VRT检出移位骨折839处,未移位骨折275处,肋软骨骨折88处。MPR对肋骨骨折的检出率明显高于SSD和VRT(P<0.05),MPR、SSD、VRT对肋软骨骨折的检出率比较差异无统计学意义(P>0.05)。CT重建技术检出胸骨骨折241处,胸椎骨折139处,锁骨骨折225处,肩胛骨骨折201处,肺挫裂伤458例,胸腔积液239例,气胸110例,肺不张55例,纵膈气肿及皮下气肿62例,肝脏包膜下出血21例。结论多层螺旋CT的MPR、SSD、VRT图像对肋骨骨折和肋软骨骨折均有较高的检出率,其中MPR对肋骨骨折诊断率更高,CT重建处理后有利于发现患者其他部位骨折及并发症。Objective To explore the clinical application value of multiplanar reconstruction(MPR),surface shade display(SSD),and volumetric reproduction technique(VRT)in rib fractures.Methods A total of 800 patients with suspected rib fractures admitted to our hospital from June 2017 to June 2018 were collected.All patients underwent X-ray and multi-slice spiral CT examination,and they were given MPR,SSD,and VRT image post-processing.The display effects of several images on rib fractures were observed.Results MPR detected 887 displaced fractures,274 undisplaced fractures and 91 costal cartilage fractures.SDD detected 841 displaced fractures,261 undisplaced fractures and 87 costal cartilage fractures.VRT detected 839 displaced fractures,275 undisplaced fractures and 88 costal cartilage fractures.The detection rate of rib fractures of MPR was significantly higher than that of SSD or VRT(P<0.05).There was no significant difference in the detection rate of costal cartilage fractures among MPR,SSD,and VRT(P>0.05).CT reconstruction technique detected 241 sternal fractures,139 thoracic fractures,225 clavicle fractures,and 201 scapular fractures.There were 458 cases of pulmonary contusion,239 cases of pleural effusion,110 cases of pneumothorax,55 cases of pulmonary atelectasis,62 cases of mediastinal emphysema and subcutaneous emphysema,and 21 cases of subcapsular hemorrhage.Conclusion MPR,SSD,and VRT images of multi-slice spiral CT have higher detection rate on rib fractures and costal cartilage fractures.MPR has higher diagnostic rate on rib fractures.CT reconstruction is beneficial to find other parts of fractures and complications of patients.
