【摘要】：目的探討浸潤(rùn)性導(dǎo)管癌(IDC)時(shí)間-信號(hào)強(qiáng)度曲線(TIC)及ADC值與組織學(xué)分級(jí)的相關(guān)性。方法回顧性分析43例(共45個(gè)病灶)經(jīng)病理學(xué)證實(shí)為IDC的動(dòng)態(tài)增強(qiáng)MRI及DWI表現(xiàn),測(cè)量腫塊的早期強(qiáng)化率、ADC值,描繪時(shí)間-信號(hào)強(qiáng)度曲線(TIC),對(duì)不同病理學(xué)分級(jí)IDC的早期強(qiáng)化率、TIC曲線分型及ADC值進(jìn)行組間比較,并分析其與病理組織分級(jí)的相關(guān)性。結(jié)果 43例IDC中,Ⅰ級(jí)8例,Ⅱ級(jí)24例,Ⅲ級(jí)11例。不同級(jí)別IDC兩兩比較,早期強(qiáng)化率的差異均無(wú)統(tǒng)計(jì)學(xué)意義(P均0.05),而TIC曲線分型、ADC值的差異均有統(tǒng)計(jì)學(xué)意義(P均0.05),IDC的TIC曲線分型與病理組織學(xué)分級(jí)呈正相關(guān)關(guān)系(r=0.40,P0.01),與ADC值呈負(fù)相關(guān)(r=-0.79,P0.01)。正常乳腺組織與不同病理組織分級(jí)IDC的ADC值差異均有統(tǒng)計(jì)學(xué)意義(P均0.05)。結(jié)論乳腺動(dòng)態(tài)增強(qiáng)MRI的TIC曲線結(jié)合ADC值可在一定程度上預(yù)測(cè)IDC的組織學(xué)分級(jí)。
[Abstract]:Objective to investigate the correlation between (IDC) time-signal intensity curve (TIC) and ADC value and histological grade in invasive ductal carcinoma. Methods the dynamic enhanced MRI and DWI findings of 43 patients (45 lesions) proved by pathology were retrospectively analyzed. The early enhancement rate, ADC value and time-signal intensity curve (TIC),) of 43 patients with IDC were measured. The early enhancement rate, TIC curve type and ADC value of IDC in different pathological grades were compared among groups, and the correlation between them and pathological grade was analyzed. Results in 43 cases of IDC, 8 cases were grade 鈪，
