Digital subtraction techniques are easily adapted to the evaluation of loosening in total hip prostheses, allowing real time review of injection dynamics and data manipulation after the study. We have successfully used both standard radiographic and digital imaging techniques in the evaluation of 15 prosthetic hip joints. The digital results are comparable to and often better than those of standard radiographic techniques for the evaluation of loosening in total hip prostheses.
数字减法技术很容易应用于全髋关节假体松动的评估，可在研究后实时查看注入动态并进行数据处理。我们已成功地使用标准放射成像技术和数字成像技术对15个人工髋关节进行评估。在评估全髋关节假体松动方面，数字成像结果与标准放射成像技术的结果相当，且往往更好。
