Abstract:
Objective To explore value of CT features in diagnosis of traumatic diaphragmatic rupture.Methods A retrospective analysis was performed on totally 256 patients with suspected traumatic diaphragmatic rupture,among them 128 were confirmed after surgery.All patients underwent CT scan before surgery.The prevalence of CT findings were recorded,including diaphragm discontinuity or segmental non-recognition of diaphragm," collar" sign," intrathoracic herniation of abdominal contents" sign," dependent viscera" sign," dangling diaphragm" sign and " thickness of the diaphragm" sign.The sensitivity and specificity of each sign were calculated.Results The sensitivity of diaphragm discontinuity or segmental non-recognition of diaphragm,"collar" sign,"intrathoracic herniation of abdominal contents" sign,"dependent viscera" sign,"dangling diaphragm" sign and "thickness of the diaphragm" sign of diaphragmatic rupture was 75.00％ (96/128),84.37％ (108/128),78.13％ (100/128),76.56％ (98/128),54.68％ (70/128) and 46.87％ (60/128),respectively.The specificity was 93.75％ (120/128),98.43％ (126/128),98.43％ (126/128),99.21％ (127/128),93.75％ (120/128) and 84.38％ (108/128),respectively.The sensitivity and specificity of overall MSCT signs was 92.18％ and 100％,respectively.Conclusion CT features have high value in diagnosis of traumatic diaphragmatic rupture.
