The comparative analysis of computer and screen-film radiography

CAO Guijing, LI Guihua, JIANG Jinkai, et al The comparative analysis of computer and screen-film radiography CAO Guijing, LI Guihua, JIANG Jinkai,et al Department of Radiology, The second people's Hospital of Liaocheng, Liaocheng, 252601,China  
Objective: To evaluate the application value of the computer radiography. Methods: One thousand and two hundred cases of computer radiographic images and 1200 cases of screen-film radiographic images were selected from our hospital to be analysed by 2 radiologists and one senior radiologist respectively. Results: ①With CR system, the quality of the image was classified into as grade A in 51.6%, grade B in 35.5%, grade C in 12.2% and waste in 0.7%. With screen-film system, the quality of the image was classified into grade A in 40.6%, grade B in 42.5%, grade C in 15.2% and waste in 1.7%. ② Compared with the screen-film system, the required voltage of CR system was 1-5 kv higher, and exposure was 20% higher. Conclusion: The CR system provided high quality image, so that reliable diagnosis could be obtained for clinical practice. The disadvantage of CR system was to require higher voltage. This will result in higher radiation dosage for the patients.
