Abstract
Objective:To analyze and compare the application values of ordinary X ray film and 64 layers spiral CT three-dimensional volume reconstruction for rib fracture.Methods:89 patients with rib fracture were selected from June 2012 to August 2014.They were respectively diagnosed by ordinary X ray film and 64 layers spiral CT three-dimensional volume reconstruction.The diagnostic sensitivitys of two check images for rib fracture were observed and compared.Results:In 89 patients with rib fracture,CT axial scanning diagnosed all rib fracture in 241,and CT axial scanning diagnosis was standard.The ordinary X ray film examination diagnosed 54 cases of fracture in 142,and the sensibility was 58.92%.64 layers spiral CT three-dimensional volume reconstruction diagnosed 83 cases of fracture in 236,and the sensibility was 97.93% .There was significant difference between the positive rate of the two,and the difference was statistically significant(P<0.01).The difference of the positive rates between ordinary X-ray and 64 layer spiral CT for rib fracture on diaphragm,subphrenic rib fracture,chest rib joints and tiny fractures was outstanding with statistical significance(P<0.01).Conclusion:The ordinary X ray only has a preliminary inspection of rib fracture,and its missed diagnosis is high.Compared with the ordinary X-ray, 64 layers spiral CT three-dimensional volume reconstruction diagnoses accurately,it is best inspection method in the diagnosis of rib fracture.关键词
