Abstract:
Objective To study the best parameters of low dose MSCT in examining the pharyngeal disease.Methods 20 volunteers were scanned by MSCT using 10 mm collimation,10 mm interval,120 kV,200 mA,100 mA,50 mA,25 mA parameters,respectively.All of the data was reformed(collimation 2.5 mm,interval 1.3 mm) on ADW 4.0 workstation.The image quality in different dose were scored respectively by 4 experienced radiolagists. Results The best appropriate parameter was 10 mm collimation,10 mm interval,120 kV,50 mA.Conclusion In examining the pharyngeal disease,the application of low dose(120 kV,50 mA) scan mode not only can assure the image quality but can decrease the exposure to patients.
