本研究旨在验证多参数内在对比MRI检查和定量化学诱导乳腺癌小鼠模型纤维化的价值,并将结果发表在Eur Radiol上。

本研究共纳入了Sprague-Dawley母小鼠18只,并进行亚硝基脲化学诱导乳腺癌。对小鼠进行9个b值扩散加权成像(DWI)、超短回波(UTE)及磁化传递(MT)磁共振加权成像(MRI),计算相关MR参数。对离题肿瘤进行组织学检查来评价坏死程度、胶原、缺氧和微血管数量。

在MR参数和苦味酸天狼猩红染色间具有显着相关性(k a 和 δ:r > 0.85, p < 0.0002,;T 1和 T 1s :r < -0.75, p < 0.001, Pearson),表示MR对乳腺癌中的胶原物质较敏感。苦味酸天狼猩红染色同样与DWI参数fD* (r=0.801, p=0.0004)和常规梯度回波T 2* (r=-0.660, p=0.0055)具有相关性。坏死率与超短/常规回波信号比具有中度相关(r=0.620, p=0.0105)。哌莫硝唑加和物(缺氧)和CD31(微血管数量)染色与所有MR参数均无相关性。

本研究表明,磁化传递MRI对检出乳腺癌患者的胶原非常有效,这也支持纳入MR成像有助于检出纤维化,从而可作为评价预后的标识物。
