摘要
目的:研究多层螺旋CT(MSCT)三维重组扫描诊断对跟骨骨折的诊断能效.方法:选取 2019年 1月—2020年 11月我院收治的 177例疑似跟骨骨折患者为研究对象.对所有受试者均开展X线检查及MSCT三维重组扫描检查.检查结果的分析均由医院 2名经验丰富的影像科医生通过双盲法完成.分析不同诊断方法应用于跟骨骨折中的诊断效能.此外,比较不同诊断方法评估骨折程度、位移情况以及关节受累情况的效能.结果:X线检查共检出跟骨骨折 113例,其中漏诊35例,误诊 7例.MSCT三维重组扫描共检出跟骨骨折141例,其中漏诊 0例,误诊 0例.以临床结合辅助检查结果为金标准,MSCT三维重组扫描诊断跟骨骨折中的灵敏度、特异度及准确度分别高于X线检查,组间差异有统计学意义(P<0.05).MSCT三维重组扫描诊断单线骨折、粉碎性骨折、碎片位移及关节受累的准确率均高于X线检查,组间差异有统计学意义(P<0.05).结论:MSCT三维重组扫描诊断对跟骨骨折的诊断能效较高,具有较为理想的灵敏度、特异度以及准确度.
Abstract
Objective:To study the efficiency of multi-slice spiral CT(MSCT)three-dimensional reconstruction scanning in the diagnosis of calcaneal fractures.Methods:177 patients with suspected calcaneal fractures admitted to our hospital from January 2019 to November 2020 were selected as the research objects.All subjects underwent X-ray examination and MSCT three-dimensional reconstruction scanning.The clinical and auxiliary examination results were used as the gold standard to analyze the diagnostic efficacy of different diagnostic methods in calcaneal fractures.In addition,the efficacy of different diagnostic methods in evaluating the degree of fracture,displacement and joint involvement was compared.Results:113 calcaneal fractures were detected by X-ray examination,including 35 cases of missed diagnosis and 7 cases of misdiagnosis.141 cases of calcaneal fractures were detected by MSCT three-dimensional reconstruction scanning,of which no case was missed and no case was misdiagnosed.Taking the clinical combined with auxiliary examination results as the gold standard,the sensitivity,specificity and accuracy of MSCT three-dimensional reconstruction scanning in the diagnosis of calcaneal fractures were higher than those of X-ray examination,and the differences between the groups were statistically significant(P<0.05).The accuracy of MSCT three-dimensional reconstruction scanning in the diagnosis of single line fracture,comminuted fracture,fragment displacement and joint involvement was higher than that of X-ray examination,and the differences between the groups were statistically significant(P<0.05).Conclusion:MSCT three-dimensional reconstruction scanning has high efficiency in the diagnosis of calcaneal fractures,with ideal sensitivity,specificity and accuracy.
