目的 探討MRI擴散加權(quán)成像在乳腺浸潤性導(dǎo)管癌新輔助化療(NAC)療效評價中的作用。
方法 30例乳腺浸潤性導(dǎo)管癌患者,術(shù)前NAC治療前后均行MRI常規(guī)掃描及擴散加權(quán)成像檢查。由兩位有經(jīng)驗的影像醫(yī)師獨立分析對比NAC治療前后腫瘤最大徑及表觀擴散系數(shù)(ADC)的變化。采用配對t檢驗分析腫瘤最大徑及ADC值變化。
結(jié)果 乳腺浸潤性導(dǎo)管癌NAC治療前的腫瘤最大徑為(4.33±0.83) cm,治療后為(2.04±0.64) cm,其腫瘤最大徑明顯縮?。≒<0.001)。b=1 000時,NAC治療前后腫瘤平均ADC 值分別為(1.89±0.15) ×10-3mm2/s和(1.14±0.31) ×10-3mm2/s,NAC治療后病灶A(yù)DC 值減?。≒<0.05)。
結(jié)論 MRI擴散加權(quán)成像可無創(chuàng)并準確地評價NAC的治療效果,有助于療效評價和手術(shù)決策。
