Abstract:
Objective To study the diagnostic value of digital mammography(DM) and color Doppler ultrasonography (CDUS) for small breast carcinoma and axillary lymph nodes metastasis.Methods DM and ultrasonographic findings of 60 cases with breast nodules less than 2.0 cm in diameter were analyzed and diagnosed by experienced radiologists and ultrasonography doctors with double blind method and compared with pathological results.Results Among 60 cases, 60 breast nodules and 96 axillary lymph nodes (45/96 metastatic nodes) were both found by DM and CDUS,including 36 cases of breast cancer and 24 cases of benign lesions. The sensitivity and accuracy of DM in diagnosis of small breast cancer and axillary lymph nodes metastasis were significantly higher than that of CDUS, especially for the lesions were less than 1 cm in size (P
