Application study of digital X-ray tissue equalization technique in the femoral neck injury

Objective To evaluate the clinical application of digital radiography(DR)tissue equalization(TE)technique in the femoral neck injury.Methods TE technique and conventional photography were used to examine 50 patients suffering from injury of the femoral neck.The image quality was evaluated by three radiological experts who were blinded to the results.The image quality was divided into five levels.Results When the TE technique was used,38 perfect images were obtained and there was no unacceptable image,while the traditional methods resulted in 12 unacceptable images and no perfect image.The TE technique is superior to the conventional radiography significantly in the lateral photography of the femoral neck(P0.05).Conclusion By using TE technique,hyperdensity and hypodensity can be displayed on one image simultaneously,and the character in the image is important in the lateral exhibition of the femoral neck.
