乳腺导管上皮内瘤变32例影像诊断分析

目的：探讨全数字化乳腺X线摄影与磁共振成像检查相结争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，DIN1A2例；DIN1B1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旱期发现具有重要意义．显著提高患者的生存质量。

Imaging Diagnosis in 32 Cases with Ductal Intraepithelial Neoplasia

Objective： To evaluate the clinical value of full--field digital mammography （FFDM） combined with Magnetic Resonance Imaging （MRI） in the diagnosis of Ductal intraepithelial neoplasia. Methods： We retrospectively analysed 32 patients with ductal intraepithelial neoplasia （DIN）, who were detected by FFDM and MRI, and pathologically confirmed. Results： In 32 DIN cases, 17 cases are usual ductal hyperplasia （UDH）, 2 cases are Flat epithelial atypia （DIN 1A）, 1 case is atypical ductal hyperplasia （DIN 1B）, 12 cases are ductal carcinoma in situ （DIN 1C-DIN3）. By using the way of FFDM combined with MRI, we made the diagnosis of breast ductal hyperplasia 18 cases, ductal carcinoma in situ 11 cases, 3 cases were failed to confirm the diagnosis. Conclusion： FFDM combined with MRI can significantly elevate the early detection ofductal carcinoma in situ, and improve the quality of life of the patients.
