Methods 42 cases mature neonate with MSCT scanning in lung were collected and randomly divided into three groups averagely. The tube current was 50 mAs and 30 mAs for low dose scanning and 200 mAs for routine dose. The CT value of region of interesting and standard deviation were measured in the aorta that region of carina of trachea. And compared the noise, image quality, CT dose index and dose length product between two low-dose scannings and routine dose.

42例足月新生儿随机等分成3组分别行低剂量30mAs、50mAs及常规剂量200m AsMSCT胸部扫描，统一于气管分叉处测量并记录主动脉CT值及标准差，比较两低剂量扫描与常规剂量扫描的噪声、图像质量、CT剂量指数和剂量长度乘积等差别。

All rats were anesthesized and ventilated mechanically with FiO2 0.5, BR 100·min-1, VT12ml·kg-1 and I/E 1/1.5. The blood was withdrawed to induce hemorrhagic shock via the carotid until blood pressure reached 45±5mmHg and lasted for 1 hour, and the shed blood and Ringers lactate in volume equal to the shed blood were reinfused for resuscitation in two hours in groups B～F . Afterwards, LPS was given via the trachea(200μg·kg-1,in 500μl normal saline) to establish the ARDS model.

所有动物均行机械通气，吸入氧浓度（FiO2 ）0.5，B～F动物在20min内自颈动脉放血至平均动脉压为45±5mmHg，休克1h后开始液体复苏，在2h内回输全部采集血液及等量平衡液，然后气管内给予内毒素200μg·kg-1。
