Forty-four pathologically proved mammary carcinomas were studied by clinical examination, xeroradiography, and ultrasonography with a dedicated whole-breast scanner. Abnormalities reflecting carcinoma were shown by echography in 90% of cases and xeromammography in 97%. Ultrasonic manifestations of malignancy were separated into four categories: (a) a solid, hypoechoic mass; (b) a hyperechoic focus; (c) an irregular, echogenic zone of parenchymal disruption; and (d) an atypical cystic mass. Dedicated ultrasound instruments enhance interpretation and improve differential diagnostic capability. Sonography demonstrates abnormalities better and permits superior definition of abnormal characteristics in a dysplastic breast than in a fatty, atrophic breast, while xeromammography may be more reliable in postmenopausal women with fatty breasts than in women with mammographically dense breasts. One limitation of current ultrasound equipment is the inability to consistently demonstrate microcalcification.
通过临床检查、干板X线摄影以及使用专用全乳扫描仪的超声检查，对44例经病理证实的乳腺癌进行了研究。90%的病例通过超声检查显示出反映癌症的异常，干板乳房X线摄影显示异常的比例为97%。恶性肿瘤的超声表现分为四类：(a)实性低回声肿块；(b)高回声灶；(c)实质破坏的不规则回声区；(d)非典型囊性肿块。专用超声仪器有助于解读并提高鉴别诊断能力。与脂肪萎缩性乳房相比，超声检查在发育异常的乳房中能更好地显示异常，并能更清晰地界定异常特征，而对于绝经后脂肪型乳房的女性，干板乳房X线摄影可能比乳房X线密度高的女性更可靠。当前超声设备的一个局限性是无法始终显示微钙化。
