需要能够以简单的方式用于评估与乳房X光摄影中的临床要求相关的图像质量的工具。这项工作的目的是调整目前的欧洲图像质量标准，使其也适用于数字乳房X光摄影图像，并使用尽可能简单和尽可能少的标准。对这套新标准进行了试点评估，对来自通用电气SenogRaphe 2000D全场数字化乳房X光摄影系统的28名妇女进行了乳房X光检查。其中一个乳房使用标准的自动曝光模式进行曝光，另一个乳房使用大约一半的吸收剂量。三位经验丰富的放射科医生使用视觉分级分析技术对图像进行了评估。结果表明，新的质量标准可以简单地用于数字化乳腺摄影中与临床要求相关的图像质量的评价。结果还表明，所使用的乳房X光摄影系统的吸收剂量可能会大幅减少。
There is a need for tools that in a simple way can be used for the evaluation of image quality related to clinical requirements in mammography. The aim of this work was to adjust the present European image quality criteria to be relevant also for digital mammography images, and to use as simple and as few criteria as possible. A pilot evaluation of the new set of criteria was made with mammograms of 28 women from a General Electric Senographe 2000D full-field digital mammography system. One breast was exposed using the standard automatic exposure mode, the other using about half of that absorbed dose. Three experienced radiologists evaluated the images using visual grading analysis technique. The results indicate that the new quality criteria can be used for the evaluation of image quality related to clinical requirements in digital mammography in a simple way. The results also suggest that absorbed doses for the mammography system used may be substantially reduced.
