Objective:To explore the chest multi-slice spiral CT examination of trauma patients,and compare the diagnostic efficacy of different levels of doctors'manual reading and intelligent software in rib fracture.Methods:150 cases of suspected traumatic rib fracture in our hospital from January 2023to June 2023 were selected,all of them were scanned by multi-slice spiral CT,and reconstructed by thin-slice and three-dimensional post-processing.Taking the comprehensive diagnosis results of clinical and surgery as the gold standard,the diagnosis results of rib fracture by manual reading and intelligent software of different levels of doctors were analyzed and compared.Results:According to the comprehensive diagnosis of clinic and operation,there were 100 cases with rib fracture(positive group)and 50 cases without rib fracture(negative group).80 cases were correctly diagnosed by junior doctors in the positive group and 40 cases in the negative group,with an accuracy rate of 80.0％,and the missed diagnosis rate and misdiagnosis rate were both 20.0％.Senior doctors diagnosed 85 cases correctly in the positive group and 45 cases correctly in the negative group,with an accuracy rate of 86.7％,a missed diagnosis rate of 15.0％and a misdiagnosis rate of 10.0％.The intelligent software correctly diagnosed 95 cases in the positive group and 50 cases in the negative group,with an accuracy rate of 96.7％,a missed diagnosis rate of 5.0％and a misdiagnosis rate of 0.0％.Comparing the diagnosis results of senior doctors,junior doctors and intelligent software,there were statistical differences in accuracy and misdiagnosis rate between the two groups(P＜0.05),but there was no statistical difference in missed diagnosis rate(P＞0.05).There were statistical differences in comparison accuracy,misdiagnosis rate and missed diagnosis rate among other groups(P＜0.05).Conclusion:In the diagnosis of rib fracture by multi-slice spiral CT scanning,the intelligent software has higher accuracy and better efficiency than the doctors with high seniority and low seniority,and can be widely used in clinic.
