64排螺旋CT在肋骨骨折诊断中的应用分析

Application of 64-slice Spiral CT in the Diagnosis of Rib Fractures

目的:研究分析64排螺旋CT在临床中治疗肋骨骨折诊断中的应用效果。方法:选择于2017年1月至2017年12月期间到我院接受治疗的264例胸部外伤患者,对其进行X线片检查以及64排螺旋CT检查,并对其CT图像进行曲面重建(CPR)、最大密度投影(MIP)、容积再现(VRT)、表面遮掩(SSD)等处理,比较检查结果的准确性。结果:(1)两种检查方式对于肋骨骨折的检出率比较:264例胸部外伤患者中,其中250例明确骨折,总计565处骨折。经过64排螺旋CT检查出545处,其骨折检出率为96.5%。X线片检查出440处,其骨折检出率为77.9%。且64排螺旋CT检查方式的检出准确率显著优于X线片检查方式的检出率,具有统计学意义(P<0.05);(2)两种检查方式对单根肋骨骨折以及多根肋骨骨折的检出率比较:检查出89处单根肋骨骨折,116处多根肋骨骨折。64排螺旋CT检查出111处单根肋骨骨折,144处多根肋骨骨折。64排螺旋CT检查方式对于单根肋骨骨折以及多根肋骨骨折的检出率显著优于X线片检查方式的检出率,具有统计学意义(P<0.05)。结论:在临床中,给予胸部外伤患者进行64排螺旋CT图像重组,能够更加全方面、多方位的观察分析其肋骨骨折的实际情况,并且可有效弥补X线片检查以及常规CT检查方式的缺点,减少误诊、漏诊的发生几率,从而为下一步治疗提供理论等基础支持,有效改善预后情况。

Objective To study the application of 64-slice spiral CT in the diagnosis of rib fractures in clinic. Methods A total of 264 patients with thoracic trauma admitted to our hospital X-ray examination and 64-slice spiral CT examination, and their CT images were reconstructed(CPR), Maximum density projection(MIP), volume rendering(VRT), surface masking(SSD) and other treatments, to compare the accuracy of test results. Results(1) Comparison of the detection rate of rib fractures between the two methods: Of the 264 cases of chest trauma, 250 cases had definite fracture and 565 cases were fractured. After 64 rows spiral CT examination of 545, the fracture detection rate was 96.5%. X-ray examination of 440, the fracture detection rate of 77.9%. The detection accuracy of 64-slice spiral CT was significantly better than that of X-ray, which was statistically significant(P<0.05).(2) The detection rate of rib fractures comparison: check out 89 single rib fractures, 116 multiple rib fractures. 144 multiple rib fractures. 64 rows of spiral CT examination to the detection rate of X-ray examination, with statistical significance(P<0.05);Conclusion In the clinic, given 64-slice spiral CT image reconstruction of patients with chest trauma can be more comprehensive and can effectively compensate for the shortcomings of X-ray examination and conventional CT examination to reduce the misdiagnosis and missed diagnosis So as to provide basic theory support for the next treatment, which can effectively improve the prognosis.
