目的探讨乳腺钼靶和超声诊断乳腺原位癌影像学特点。方法对比21例手术后病理证实的乳腺原位癌患者的钼靶与超声诊断结果。结果 21例患者在乳腺钼靶摄片上有乳腺癌征象的15例(71.4%);在乳腺超声诊断中有乳腺癌表现的8例(38.0%)。结论在乳腺原位癌诊断方面,乳腺钼靶诊断与病理诊断的符合率高于乳腺超声检查;两种检查结合诊断可减少此类早期乳腺癌的漏诊。
Objective To investigate the mammographic features of breast mammography and ultrasound in the diagnosis of breast carcinoma in situ. Methods The molybdenum target and ultrasound diagnosis results of 21 cases of breast carcinoma in situ confirmed by pathology after operation were compared. Results Twenty-one patients (71.4%) had breast cancer sign on mammography, and 8 patients (38.0%) had breast cancer. Conclusions In the diagnosis of breast carcinoma in situ, the coincidence rate of mammography and pathological diagnosis is higher than that of breast ultrasonography; combined diagnosis of both mammograms can reduce the missed diagnosis of this type of early breast cancer.
