The visual evaluation of x-ray images is very useful. We applied two different methods of evaluation for breast computed radiography(CR)images in this work : one method was an analytical evaluation that detected the strongest "RE" parameter, while the other method was a preference evaluation that selected the most suitable "RE" parameter. We found little difference when the analytical method was used for the evaluation of breast CR images, whereas remakable differences were obtained with the preference method. To conclude, it is very important to use a proper method in the visual evaluation of x-ray images.
