摘　　要：目的探究胸骨骨折的MSCT轴面和多平面重组表现及其诊断方法。方法方便选取该院2015年3月—2017年3月因车祸所致胸骨骨折患者112例,将这些患者分为观察组和对照组,每组56例,对照组实施16层螺旋CT胸部扫描,观察组在MPR图像及轴位图像上对患者胸骨骨折的数量,解剖部位、断端移位及类型情况进行观察,比较两组患者的胸部其他部位发生创伤的情况。结果常规轴位的胸骨骨折检出率为80.0%(24/30),(χ~2=6.667,P<0.05);横行骨折检出率80.0%(12/15)(χ~2=0.606,P>0.05);未发生分离移位骨折检出率为66.7%(8/12),(χ~2=4.800,P<0.05);MPR胸骨骨折检出率为100.0%(30/30),横行骨折检出率100.0%(15/15),未发生分离移位骨折检出率为100.0%(12/12),常规轴位CT扫描的横行骨折及未发生分离移位骨折的检出率低于MPR,比较差异有统计学意义(P<0.05);胸骨骨折患者与未合并胸骨骨折在胸腔性积液、多发性肋骨骨折及创伤性湿肺发生率比较差异有统计学意义(P<0.05)。结论对于骨折患者的选择诊断方式要根据患者发生移位情况,如果移位情况较明显,可用常规的横断面,如果移位不明显时,就需结合MSCT。当患者发生胸骨骨折后并发症发生率就会增高,会加重患者的病情,因此为增加检查准确率,需结合MSCT和MPR。Objective To investigate the manifestation and diagnosis of MSCT axial and multiplanar remodeling of sternal fractures. Methods A total of 112 patients with sternal fractures caused by ear accident from March 2015 to March 2017 were convenient enrolled. The patients were divided into observation group and control group, 56 eases in each group. The control group was treated with 16-slice spiral CT chest scan. The group observed the number of sternal fractures, anatomical location, displacement and type of sternal fractures in MPR images and axial images, and compared the trauma of other parts of the chest in the two groups. Results The detection rate of sternal fracture in the normal axial position was 80.0% （24/30）, （χ^2=6.667, P〈0.05）. The detection rate of transverse fracture was 80.0%（12/15）（χ^2=0.606, P〉0.05）; The detection rate of isolated and displaced fractures was 66.7% （8/12）, （χ^2=4.800, P〈0.05）; the detection rate of MPR sternal fracture was 100.0% （30/30）, and the detection rate of transverse fracture was 100.0%（15/15）. The detection rate of non-separated and displaced fractures was 100.0% （12/12）. The detection rate of transverse axial fractures and non-dissociated fractures with conventional axial CT scans was lower than that of MPR, which was statistically significant （P〈0.05）; The incidence of ster- nal effusion, multiple rib fractures and traumatic wet lung was statistically significant in patients with sternal fractures and without sternal fractures （P〈0.05）. Conclusion The choice of diagnosis for patients with fractures should be based on the patient＇s displacement. If the displacement is more obvious, the conventional cross-section can he used. If the displacement is not obvious, MSCT should be combined. When the patient has a sternal fracture, the incidence of complications will in- crease, which will aggravate the patient＇s condition. Therefore, in order to increase the accuracy of the examination, it is necessary to combine MSCT a
