Abstract：Objective To evaluate the clinical application value of 320-row computed tomography (CT) on target scanning mode for infants' chest.Methods Eighty infants were taken chest scan with 320-row CT Toshiba Aquilion ONE,divided into two groups based on the visiting sequence,and used volume scanning and target scarming,respectively.The computed tomography dose index-volume (CTDIvol) and dose length product (DLP) were recorded every time,meanwhile,image quality was evaluated and image noise was measured.Results No differences were found in CTDIvol,DLP and effective dose (ED) between target and volume scanning mode (P＞0.05),or in the subjective evaluation of image qualities in the apex of lung (P＞0.05).There were significantly different in aortic arch,middle of left atrium and the bottom of lung between target and volume scanning mode(P＜0.001).Conclusion Target scanning mode in the infants' chest scan has greater advantages in providing high quality images without additional radiation dose than normal volume scanning mode.
