Eur Radiol:用MRI看肛管鳞癌,那得先选个有用的序列来看!

2017-11-27 shaosai MedSci原创

本研究比较T2加权(T 2-w)和扩散加权成像(DWI)MRI在测量肛管鳞癌(SCCA)最大肿瘤直径(MTD)与大体肿瘤体积(GTV)的价值并评价序列对肿瘤(T)分级的影响。其次,评价组间一致性及观察者测量肿瘤边界信心,并将结果发表在Eur Radiol上。

本研究比较T2加权(T 2-w)和扩散加权成像(DWI)MRI在测量肛管鳞癌(SCCA)最大肿瘤直径(MTD)与大体肿瘤体积(GTV)的价值并评价序列对肿瘤(T)分级的影响。其次,评价组间一致性及观察者测量肿瘤边界信心,并将结果发表在Eur Radiol上。

分别由两位放射科医生(分别具有肛管肿瘤MRI诊断经验0、5年)独立的评价45例SCCA患者(女性25例)的MRI检查分级。分别在T 2-w和高b值DWI图像上对肿瘤的MTD和GTV进行勾画,并在序列间进行比较;根据MTD进行肿瘤分级。评价两位观察者的组间一致性及勾画信心评分(1-5)。

DWI图像上的GTV和MTD要显着低于T 2-w序列(两位观察者结果分别为14.80%/9.98% (MTD)、29.70%/12.25% (GTV)),导致在1/4的病例T分级不一致。DWI序列的Bland-Altman一致性界限较窄,内部相关系数较高。DWI序列的勾画信心较高:每位观察者对40/42例评分很有信心(4或5分),而T 2-w序列上仅有31/36例诊断信心较高。

本研究表明,序列的选择会影响SCCA肿块的测量及T分级。DWI显示出较高的组间一致性及较高的肿瘤勾画信心。
