目的探讨数字化乳腺摄影与彩色多普勒超声对小乳癌及腋淋巴结转移的诊断价值。方法60例≤2.0cm(包括未形成肿块的早期乳腺癌)乳腺结节的数字化影像和超声资料分别由影像和超声医师用双盲法分析,定性诊断,并与病理对照。结果60例中,乳腺癌36例,良性病变24例;发现腋淋巴结96个,45个有转移。数字化摄影和超声在诊断小乳癌的敏感性、准确性及腋淋巴结转移的敏感性方面,二者差异显著(P(0.05);对直径≤1.0cm的病灶,数字化摄影的准确性明显高于超声(P(0.05)。结论对小乳癌及其腋淋巴结的定性诊断方面,数字化摄影为首选,二者结合有利于发现更早期的乳腺癌。
Objective To investigate the diagnostic value of digital mammography and color Doppler ultrasound in small breast cancer and axillary lymph node metastasis. Methods The digital images and ultrasound data of 60 cases ≤2.0cm (including early breast cancer without lumps) were analyzed by double-blind method by imaging and sonographers respectively, and diagnosed by pathology. Results 60 cases, 36 cases of breast cancer, benign lesions in 24 cases; found axillary lymph nodes 96, 45 have metastases. Digital photography and ultrasound in the diagnosis of small breast cancer sensitivity, accuracy and sensitivity of axillary lymph node metastasis, the difference was significant (P (0.05); for diameter ≤ 1.0cm lesions, the accuracy of digital photography was significantly higher than ultrasound (P0.05) .Conclusion Digital photography is the first choice for the qualitative diagnosis of small breast cancer and its axillary lymph nodes, and the combination of the two can help to find out more early breast cancer.
