摘　　要：目的探讨数字 X 线摄影(DR)组织均衡技术在股骨颈外伤的应用价值。方法对50例股骨颈外伤患者应用 DR 的常规摄影技术和组织均衡技术进行对比研究,同时使用 DR 组织均衡技术中的参数进行对照研究,由3名影像学专家采用双盲法对不同方法产生的图像质量进行评价,主观图像质量分5级进行评分。结果 50例应用组织均衡技术得到优质图像38例,无法接受的图像质量为0;而常规摄影优质图像质量为0,无法接受的图像质量为12例,经统计学分析,差异有统计学意义(P<0.05)。结论 DR 组织均衡技术可使高密度组织与低密度组织在1幅图像上同时显示出来,层次丰富的图像,对良好地显示股骨颈侧位尤为重要。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 （ P 〈 0. 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.
