【摘要】：目的:探討非特異性乳腺炎的MRI表現(xiàn)及與乳腺癌的鑒別診斷。方法 :分析2013年1月—2016年3月病理證實的非特異性乳腺炎29例30個病灶的MRI表現(xiàn),同時隨機抽取相同時段經(jīng)病理證實的乳腺癌患者20例作為對照組,比較2組間在MRI平掃、DWI、DCE、EER、時間-信號曲線(TIC)、MIP表現(xiàn)的異同。結(jié)果:30個炎性病變,13例病變區(qū)含有脂肪信號,全部病例于T2WI均見有高信號;28例病變環(huán)狀強化或伴強化分隔,29例DWI呈高信號,ADC值平均(0.707±0.181)×10-3 mm2/s,其中53.3%的病例0.700×10~(-3)mm~2/s;73.3%的TICⅠ型;EER:平均123%±50%,80%26例,≤80%4例。MIP:21例血運增加。20例乳腺癌,2例于T2WI呈稍高信號,10例表現(xiàn)為向心性環(huán)狀強化;DWI均呈高信號,ADC值平均(0.874±0.108)×10-3 mm2/s,2例0.700×10~(-3)mm~2/s,85%的TIC為Ⅱ~Ⅲ型;EER:平均137%±36%,80%19例,≤80%1例;MIP:16例血運增加。以≤0.700×10-3 mm2/s為炎性病變,ADC值對炎性病變的敏感性88.89%,特異性56.25%,準確性68%,二者之間的差異有統(tǒng)計學意義(χ~2=6.74,P0.01)。TIC以Ⅰ型為良性病變,Ⅱ、Ⅲ型為惡性病變,TIC在二者之間有統(tǒng)計學意義(χ~2=16.33,P0.01);EER及MIP在二者之間沒有統(tǒng)計學意義(χ~2=0.23(校正),P0.05;χ~2=0.62,P0.05)。結(jié)論 :非特異性乳腺炎MRI表現(xiàn)具有一定特征性,MRI平掃結(jié)合動態(tài)增強掃描形態(tài)學及血流動力學參數(shù)對乳腺癌的鑒別診斷有重要價值。
[Abstract]:Objective: to investigate the MRI features of non-specific mastitis and its differential diagnosis with breast cancer.Methods: the MRI findings of 30 lesions in 29 patients with pathologically proved nonspecific mastitis from January 2013 to March 2016 were analyzed. 20 patients with breast cancer confirmed by pathology at the same time were randomly selected as control group.To compare the differences and similarities between the two groups in MRI plain scan of DWI and DCEE, time-signal curve.Results: there were 30 inflammatory lesions with fatty signal in 13 cases, all of them had hyperintense lesions with or without circular enhancement or enhanced septum. 29 cases of DWI showed high signal intensity of 0.707 鹵0.181) 脳 10 ~ (-3) mm ~ (2) / s, of which 53.3% were 0.700 脳 10 ~ (-3) mm ~ (-2) / s of TIC type 鈪，
