目的探讨全数字化乳腺X线摄影对导管原位癌的诊断价值。方法收集经手术及病理证实的乳腺导管原位癌32例,术前均行全数字化X线摄影检查,回顾性分析其X线征象。结果 32例乳腺导管原位癌,显示恶性钙化29例,其中单纯钙化15例,钙化伴肿块4例,伴结构扭曲2例,伴局灶性致密影8例,另3例未发现明显恶性征象。全数字化X线摄影对乳腺导管原位癌的诊断符合率为81.25%。结论全数字化X线摄影对乳腺导管原位癌的诊断具有很高的价值;钙化是乳腺导管原位癌最常见的X线征象,结构紊乱和局灶性致密影是乳腺导管原位癌最容易忽略的X线表现。
Objective To investigate the value of full digital mammography in the diagnosis of ductal carcinoma in situ. Methods Thirty-two cases of ductal carcinoma in situ were collected surgically and pathologically. All patients underwent digital radiography before operation. The X-ray findings were retrospectively analyzed. Results 32 cases of ductal carcinoma in situ showed 29 cases of malignant calcification. There were 15 cases of simple calcification, 4 cases of calcification with mass, 2 cases of structural distortions, 8 cases of focal dense densification and 3 cases of malignant lesions . Full digital radiography in diagnosis of ductal carcinoma in situ in duct was 81.25%. Conclusions Digitalized radiography is of great value in the diagnosis of ductal carcinoma in situ. Calcification is the most common X-ray sign of ductal carcinoma in situ. It is most likely that the structural disorder and focal dense shadow are the most common ductal carcinoma in situ Ignored X-ray performance.
