复杂部位骨折诊断中128排螺旋CT图像后处理技术的应用价值

Application Value of 128 Row Spiral CT Image Post-Processing Technology in Diagnosis of Complex Site Fractures

目的评估复杂部位骨折患者实施128排螺旋CT图像后处理技术检查的准确率。方法选取2021年1月—2023年7月本院收治的疑似复杂部位骨折患者57例,全部患者均予以常规X线检查、128排螺旋CT图像后处理技术检查,总结两种检查结果,针对其准确性实施组间对照。结果①疑似复杂部位骨折患者确诊结果阳性39例,占比68.42%;阴性18例,占比31.58%。常规X线检查结果阳性36例,占比63.16%;阴性21例,占比36.84%。128排螺旋CT图像后处理技术检查结果阳性38例,占比66.67%;阴性19例,占比33.33%。②疑似复杂部位骨折患者128排螺旋CT图像后处理技术检查结果灵敏度、特异度、准确性、阳性预测值、阴性预测值(97.44%、100.00%、98.25%、100.00%、94.74%)高于常规X线检查(79.49%、72.22%、77.19%、86.11%、61.90%),期间校验值显示为P<0.05,结果充分证实组间差异存在。结论复杂部位骨折患者采用128排螺旋CT图像后处理技术检查准确性较高。

Objective To evaluate accuracy of 128 slice spiral CT image post-processing technology for patients with complex site fractures.Methods The paper chose 57 patients with suspected complex site fractures admitted to our hospital from January 2021 to July 2023,treated with routine X-ray examination and 128 slice spiral CT image post-processing technology examination,summarized examinations results and compared accuracy between groups.Results①39 cases with suspected complex site fractures were diagnosed positive,accounting for 68.42%;18 cases were negative,accounting for 31.58%.36 cases were positive by routine X-ray examination,accounting for 63.16%;21 cases were negative,accounting for 36.84%.Post-processing technology of 128 row spiral CT images showed positive for 38 cases,accounting for 66.67%;19 cases were negative,accounting for 33.33%.②Sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of 128 slice spiral CT image post-processing technology examination(97.44%,100.00%,98.25%,100.00%,94.74%)for suspected complex site fractures was higher than routine X-ray examinations(79.49%,72.22%,77.19%,86.11%,61.90%).Validation value during the period showed P-value<0.05,which fully confirmed difference between groups.Conclusion 128 row spiral CT image post-processing technology can achieve relatively high accuracy for patients with complex site fractures.
