数字化乳腺摄影的临床应用价值

The Clinical Value of Digital Mammography

目的探讨数字化乳腺摄影在临床工作中的应用价值。资料与方法按顺序抽取接受数字化乳腺摄影和传统屏片乳腺摄影检查的各500例患者的影像资料,就其图像病变显示率、摄片质量及照射剂量进行对比评价。结果(1)数字化乳腺摄影与传统屏片乳腺摄影对病变显示率的比较如下:微小钙化分别为26%和11.2%(P=0.000),肿块分别为15.2%和10.8%(P=0.039),结构扭曲分别为18%和8.8%(P=0.000),皮肤、乳头影改变分别为4.8%和1.8%(P=0.008)。两组差异有统计学意义。(2)照射剂量及重检率比较:数字化乳腺摄影照射剂量较传统屏片乳腺摄影减少,因设备因素引起的重检率为0;传统屏片乳腺摄影因设备因素引起的重检率为1.4%。结论数字化乳腺摄影检查技术及图像的病变显示率均优于传统屏片乳腺摄影。数字化乳腺摄影系统操作简便、成像快捷、辐射较低,具有较高的临床应用价值。

Objective To investigate the clinical value of digital mammography. Materials and Methods We collected 500 images of digital mammography and screen-film mammography respectively. Display of diseases, quality of images and radiation doses were compared. Results （ 1 ） Digital mammography with traditional screen-film mammography of the disease showed that rates were as follows ： microcalcification 26% vsl 1.2% , P = 0. 000, mass 15.2% vsl0.8% , P = 0. 039, architectural distortion 18% vs8.8% , P = 0. 000, skin and nipple changes affect 4.8% vsl. 8%, P = 0. 008. There was a significant difference between the two groups. （2） Radiation doses and ratio of repeat radiation： radiation doses of digital mammography were reduced, the ratio of repeat digital vaammography was zero. The ratio of repeat traditional film-screen mammography was 1.4%. Conclusion Digital mammography is superior to traditional screen-film mammography in technology and quality of diagnostic image, digital mammography has a higher clinical application value and should be used widely,
