目的：探讨乳腺动态增强 MR 形态学表现在非哺乳期乳腺炎性病变的诊断价值。方法回顾性分析经临床穿刺病理证实的15例非哺乳期乳腺炎性病变患者的 MR 动态增强资料，分析病变分布及动态增强形态学特征。结果15例非哺乳期乳腺炎性病变分为导管炎型6例、导管炎合并肉芽肿型5例、导管炎合并脓肿型2例、囊肿伴感染型2例。非哺乳期乳腺炎性病变动态增强特征性表现为快速强化，同层动态增强病灶形态表现为离心性强化，边界模糊，与正常腺体间分界不清，患侧乳房周围血供增多。结论非哺乳期乳腺炎性病变动态增强形态学有特征性表现，当病变血流动力学信息提取困难时，动态增强的形态学提供了重要信息。

Objective To assess the value of the dynamic enhanced MR (DE-MRI)morphological features in diagnosis of non lac-tation mastitis.Methods We retrospectively studied the breast DE-MRI image data of 1 5 patients with non lactation mastitis con-firmed by pathology were retrospectively studies and the lesion morphological features and distribution were analyzed.Results Amonge 1 5 patients with non lactation mastitis,6 cases were the plasma cell mastitis,5 cases were granulomatous mastitis,2 cases were abscess,and 2 cases were cyst associated with inflammation.The typical features of non lactation mastitis on DE-MRI were fast wash-in,centrifugal enhancement sign,blur boundaries between lesions and normal breast tissue,increasing unilateral vessel sign in diseased breast.Conclusion Breast DE-MRI can show typical morphological features of non lactation mastitis.When dynam-ic information is obtained inconveniently,these are helpful in diagnosing and differential diagnosing non lactation mastitis.
