Abstract:
Objective To study the Value of low dose CT scanning with gas-contrasted and low window level in diagnosing gastro-colon lesions.Methods 126 cases suspected with gastro-colon lesions were randomly devided into two groups,group A(69 cases) were scanned with conventional water-contrast or non-contrast and conventional expose dose,and with conventional window level,group B(57 cases) were scanned with gas-contrasted and low expose dose,and using low window level.The images were evaluated by 2 experienced radiologists,the results including doctor's self-confidence and diagnostic accurate rate in both group A and group B were compared based on the endoscopic results.Results The diagnostic self-confidence of radiologists and the accurate rate in evaluating the lesions in group B were obviously superior to group A.Conclusion CT scanning of gastro-colon with gas-contrasted,low expose dose and low window level is markedly superior to conventional one.
