【摘要】：目的:應(yīng)用3D MPRAGE雙倍Gadobutrol延遲增強(qiáng)掃描技術(shù)對(duì)與皮層相關(guān)腦轉(zhuǎn)移瘤的分型及定義。方法 :回顧性分析經(jīng)本院病理證實(shí)腦轉(zhuǎn)移瘤患者25例,所有患者均行常規(guī)軸位T1WI、T2WI和FLAIR及3D MPRAGE序列延遲增強(qiáng)掃描。在3D MPRAGE增強(qiáng)掃描圖像上對(duì)轉(zhuǎn)移瘤進(jìn)行分型及定義,分三型:Ⅰ型為轉(zhuǎn)移瘤完全位于腦皮層內(nèi),瘤體直徑小于皮層寬度。Ⅱ型轉(zhuǎn)移瘤邊緣緊鄰腦皮層邊緣。Ⅲ型為轉(zhuǎn)移瘤橫跨在腦皮髓交界區(qū),侵入髓質(zhì)內(nèi)。結(jié)果:應(yīng)用3D MPRAGE雙倍劑量Gadobutrol延遲增強(qiáng)技術(shù)發(fā)現(xiàn)與皮層相關(guān)轉(zhuǎn)移瘤121個(gè),Ⅰ型病灶6個(gè),Ⅱ型病灶10個(gè),Ⅲ型病灶105個(gè),Ⅲ型占總比例的95.7%,轉(zhuǎn)移瘤直徑與分型呈正相關(guān)rs=0.441,P0.05。結(jié)論:根據(jù)3D MPRAGE雙倍Gadobutrol延遲增強(qiáng)掃描技術(shù)可以顯示腦皮層與轉(zhuǎn)移瘤的關(guān)系,與皮層有關(guān)的轉(zhuǎn)移瘤分為三型。Ⅲ型明顯多于Ⅰ和Ⅱ型。
[Abstract]:Objective: to study the classification and definition of cortical related brain metastases by using 3D MPRAGE double-fold Gadobutrol delayed enhanced scan. Methods: Twenty-five patients with brain metastases confirmed by pathology in our hospital were retrospectively analyzed. All patients underwent conventional axial T _ 1WI T _ 2WI, flair and 3D MPRAGE sequences. The metastatic tumors were classified and defined on 3D MPRAGE images. The metastatic tumors were classified into three types: type 鈪，
