ABSTRACT
Objective To explore the value of high sensitivity total spine digital radiography in radiation protection and clinical application.Methods A total of 90 patients suffering from scoliosis were randomly divided into three groups with different sensitivity such as S200,S400 and S800.All of them were examined with anterior-posterior and lateral full length spine digital radiography.The S400 group was designated as control group.The doses (mGy) and exposures (mAs) resulted from different groups were calculated and compared,including their means and deviations.Image quality was evaluated with blind method.Results In the S800 group,the doses and exposures were about 43% and 41% compared to the S400 group.The differences were statistically significant (t =4.573,8.038,P < 0.05).Doses and exposures in the S200 group were about 187% and 178% compared to the control group.The differences were also significant(t =-5.624,-4.052,P < 0.05).In the S200 and S400 group,image quality of anterior-posterior and lateral position was 100% good.When sensitivity was S800 was selected,image quality of the anterior-posterior position was 100% good,and 97% for lateral images.One lateral image was considered noisy.Conclusions In full length spine radiography,high sensitivity (S800) could greatly reduce radiation dose to patients.It is a good choice to use the sensitivity to observe wide-range spine.
