Clinical Application Comparison of DR and CR Chest Photograph

Huang Kui (Department of Radiology,the Shunde District First People's Hospital of Foshan City,Guangdong Province,Foshan 528300,China)  
Objective:To investigate the DR and CR chest radiography clinical value.Methods:Random sample the chest slice data that DR and CR chest photograph 120 for each sufferer to carry on a comparison.Results:The DR chest photographs,the 15 ses acquires image and photographs the speed as about 60 people after exposing to end(?)h,the first grade slice is 115(95.83%),the second grade slice is 5(4.17%),there is no C grades slice and discards a slice.The CR photographs and needs to replace IP plank,time of scanning of each IP plank 1.5 mins,photograph the speed as about 35 people(?)h,the first grade slice is 113(94.17%),the second grade slice is 4(3.33%),C grade slice 2(1.67%),discard slice 1(0.83%).Through statistics learn to analyze a rate and CR set to relatively have no obvious difference,have no statistics to learn meaning(χ~2=0.35,P0.05).Conclusion:CR and DR of converting the X line image information as number image is a little bit common information,handle after canning carry on various picture,for the detail observation in the image diagnosis,front and back contrast and quantitative analysis provided technique support.
