多层螺旋CT轴位与两种图像后处理技术在肋骨骨折诊断的准确性分析

Accuracy Analysis of Axial Multislice Computed Tomography and Two Image Postprocessing Techniques in the Diagnosis of Rib Fractures

目的 分析层螺旋CT轴位与两种图像后处理技术在肋骨骨折诊断的准确性。方法 收集2020年8月至2021年8月期间我院入住且符合本研究纳入标准的肋骨骨折患者80例,以随机数表法将患者进行分组,组别设为对照组(40例)、观察组(40例),对照组使用多层螺旋CT轴位检查,观察组在多层螺旋CT轴位检查的基础上加入图像后处理技术,对比两组检验准确率以及检验各项指标。结果 以手术病理诊断作为金标准,观察组检验准确率100.00%显著高于对照组90.00%,P<0.05;以病理诊断作为金标准,观察组骨折不同部位诊断准确率与对照组对比无统计学差异,P>0.05;观察组合并其他损伤检出率为87.50%,较对照组检出率55.56%得到显著提升,P<0.05;观察组检查时间与对照组对比无较大差异,P>0.05。观察组诊断图像处理时间、诊断费用高于对照组,P<0.05。结论 肋骨骨折诊断的过程中使用多层螺旋CT轴位检查具有较高的检验准确率,可以对骨折类型进行判断,但是对于隐匿性骨折检验的准确率不足,因此加入两种图像后处理技术,通过VR、SSD三维重建,对图像进行更加科学的处理,提升诊断质量,值得临床推广普及。

Objective To analyze the accuracy of slice spiral CT axial with two image postprocessing techniques in the diagnosis of rib fractures.Methods A total of 80 patients with rib fracture who were admitted to our hospital between August 2020 and August 2021 and met the inclusion criteria of this study were collected,and the patients were divided into groups according to a random number table,and the groups were as follows:control group(n=40),observation group(n=40),control group using axial examination with multislice spiral CT,observation group adding image postprocessing technique on the basis of axial examination with multislice spiral CT,Two groups were contrasted to test accuracy as well as to test each measure.Results Using surgical pathological diagnosis as the gold standard,the test accuracy of 100.00%in the observation group was significantly higher than that of 90.00%in the control group,P<0.05;taking pathological diagnosis as the gold standard,the diagnostic accuracy of different parts of fracture in the observation group had no statistical difference compared with the control group,P>0.05;the 87.50%detection rate of other injuries combined with the observation group was significantly improved from the 55.56%detection rate in the control group,P<0.05;there was no major difference in examination time between observation group and control group,P>0.05.Diagnostic image processing time and diagnostic expense were higher in the observation group than in the control group,P<0.05.Conclusions The use of axial multislice computed tomography during the diagnostic work-up of rib fractures has a high test accuracy and can judge the type of fracture,but it is not sufficiently accurate for detecting occult fractures,so the addition of two image postprocessing techniques,three-dimensional reconstruction with VR and SSD,to more scientific processing of images and improve the quality of diagnosis,It deserves clinical promotion and popularity.
