目的:探讨全数字化乳腺X线摄影与磁共振成像检查相结合对乳腺导管上皮内瘤变(DIN)的诊断价值。方法:对32例经乳腺平板数字X线摄影及磁共振检查并且病理证实为乳腺导管上皮内瘤变的病例进行回顾性分析。结果:32例DIN中,普通导管上皮增生(UDH)17例,DIN1A 2例;DIN1B 1例;乳腺导管原位癌(DIN1C-DIN3)12例。采用全数字化X线乳腺摄影与MRI相结合诊断乳腺增生18例,乳腺导管原位癌11例,3例未能明确诊断。结论:平板数字X线乳腺摄影及磁共振成像综合诊断,对乳腺导管原位癌的早期发现具有重要意义,显著提高患者的生存质量。
Objective: To investigate the diagnostic value of all-digital mammography combined with magnetic resonance imaging in the diagnosis of ductal intraepithelial neoplasia (DIN). Methods: A retrospective analysis was performed on 32 cases of breast ductal intraepithelial neoplasia confirmed by digital mammography and magnetic resonance imaging. Results: There were 17 cases of normal ductal epithelial hyperplasia (UDH), 2 cases of DIN1A, 1 case of DIN1B and 12 cases of ductal carcinoma in situ (DIN1C-DIN3) in 32 cases of DIN. 18 cases of mammary gland hyperplasia and 11 cases of ductal carcinoma in situ were diagnosed by using all-digital X-ray mammography and MRI. Conclusion: The combination of digital radiography and magnetic resonance imaging in the diagnosis of ductal carcinoma in situ is of great significance to improve the quality of life of patients.
