Objective To evaluate the practical application value of low-dose CT chest screening with 320 slice vol-ume in health examination .Methods The materials of 380 people over 40 years old who were scanned with lowdose (120 kV ,20 mA) CT chest screening fromD ecember 2013 to January 2014 at the Health management Center in Tian-jin Sanatoriumof Beijing military Region were retrospectively analyzed.The radiation dosage values were conducted statistically and the image quality and pulmonary lesions were analyzed .Results All people successfully completed the scanning and the images met with the diagnostic criteria.185 people were found chest abnormalities with 217 positive signs,including 160 cases with single positive signs,25 cases with two or more than two kinds of positive signs.DLP was 32 . 30~66 . 90 ( mGy·cm) ,the mean value was(44 .30 ± 4 .10 )( mGy·cm) .The effective radiation dose (ED) value was(0.75±0.07)mSv.Conclusion The method oflow-dose CT chestscreening with 320 slice volume can be used for large scale chest physical examination of people over the age of 40 .
