At the same time,all images were appraised by two doctors. Results Adjustment of children′ s head scanning parameter could reduce the radiation dosage obviously, and no influence for diagnosis. Conclusion It′s no affect for diagnosis to improve children′s head CT scanning parameter, and leads reduction of CT dosage obviously.
