The Study of Low Dose CT in Chest Trauma with 16 Slices Helical CT
Abstract：Objective:To assess the diagnostic value of low-dose 16 slices helical CT study in thoracic injury.Method:30 patients with thoracic trauma underwent standard-dose(200 mA) CT study and low-dose followup CT study (50 mA) within a short period.Diagnostic value,image quality and radiation dose of these two studies were compared.Result:There was no statistical significant difference between the two examinations in revealing injury.Although there was more noise in the low-dose study image in mediastinal window,image quality was acceptable and it did not affect the diagnosis.Low dose CT exam can reduce the radiation dose dramatically.CTDIvol and DLP decrease about 75%on average.Conclusion:The low-dose 16 slices helical CT scan is suitable for thoracic trauma study.On the premise of image quality,this method could not only reduce the radiation dose,but also could extend the device life.
