This retrospective study consisted of 17 consecutive patients with oligodendrogliomas. We qualitatively and quantitatively assessed the diagnostic value of fluid-attenuated inversion-recovery (FLAIR) images compared with T2-weighted fast spin-echo (FSE) images for evaluating intracranial oligodendrogliomas. Qualitative evaluations of signal intensity, tumor conspicuity, definition of tumor margin, distinction between solid and cystic-like parts within tumor, and calcification were performed. Quantitative criteria comparing FLAIR to T2-weighted FSE images included tumor-to-background contrast and contrast-to-noise ratio (CNR) and tumor-to-cerebrospinal fluid (CSF) contrast and CNR. Our results demonstrate that the FLAIR sequence can replace the T2-weighted FSE sequence for evaluating oligodendrogliomas.
这项回顾性研究纳入了17例连续的少突胶质细胞瘤患者。我们定性和定量评估了液体衰减反转恢复（FLAIR）图像与T2加权快速自旋回波（FSE）图像在评估颅内少突胶质细胞瘤方面的诊断价值。对信号强度、肿瘤显影、肿瘤边界清晰度、肿瘤内实性与囊样部分的区分以及钙化进行了定性评估。将FLAIR图像与T2加权FSE图像进行比较的定量标准包括肿瘤与背景对比度及对比噪声比（CNR），以及肿瘤与脑脊液（CSF）对比度及CNR。我们的结果表明，FLAIR序列可替代T2加权FSE序列用于评估少突胶质细胞瘤。
