Standard mammograms from 33 patients with surgically proved adenocarcinoma or fibrocystic disease were analyzed with a scanning microdensitometer and computer. A quickly computable number called the linear mass ratio is introduced. This simple ratio discriminated correctly between the 16 adenocarcinomas and 17 fibrocystic lesions of the study, all cases in which diagnosis had required biopsy.
对33例经手术证实为腺癌或纤维囊性疾病患者的标准乳房X线照片，用扫描显微密度计和计算机进行了分析。引入了一个称为线性质量比的可快速计算的数值。这个简单的比值在该研究的16例腺癌和17例纤维囊性病变之间做出了正确区分，所有病例的诊断均需活检。
