计算机图像处理在乳腺钼靶片的临床应用(附36例乳腺癌分析)

Clinical Application of Digital Inspection in Mammogram ——A Report of 36 cases of Breast Cancer

目的：应用计算机图像处理技术处理乳腺钼靶片，提高Ｘ线片的分辨率和诊断准确性。材料和方法：分析３６例５９张致密型乳腺钼靶Ｘ线片，全部病例均经手术病理证实为乳腺癌；通过计算机采用各种不同图像处理方法处理５９张原Ｘ线片，并加以分析。结果：原乳腺Ｘ线片中未能显示肿块者５０张（８４７％），疑似肿块者９张（１５３％）。经处理后得以明确显示的３５张（５９３％），较原片显示清楚的２０张（３３９％），仍未显示的４张（６８％）。致密型乳腺Ｘ线片，经计算机图像处理后乳腺癌肿块检出率达９３２％。结论：计算机图像处理，在乳腺钼靶片的应用中具有提高诊断准确性的价值，特别是对致密型乳腺，临床可扪及肿块，而Ｘ线片因腺体密实而不能显示时，有一定的实用价值和临床意义。

PURPOSE:To improve the resolution of mammogram and accuracy of diagnosis by applicafion of digital inspection. MATERIALS AND METHODS:36cases (59 film)of dense breast was analysed. All cases was proved to be carcinoma of breast by pathology. All the original X-ray film were treated by digital inspection technique. A comparison was performed between the imaging of the original X-ray film and those after digital inspection treatment. RESULTS:The tumor mass could not be clearly identifed in 50 original X-ray films (84 7%).ln the remainning 9 films the tumor masses were only suspecions (15 3%),while using digital inspection the tumor masses were definitely shown in 35 film(59 3%).The masses could be better circumscribed than the original one in 20 films(33 9%).There were only 4 films (6 8%)in which the tumor mass still could not be clearly shown. As a whole the tumor masses could be definitely identified in 93 2% of all cases in our study. CONCLUSION: The accuracy of diagnosis was improved by application of digital inspection in mammogram especially in the dense breast. The method we used is valuable in the clinic.
