A comprehensive dataset of germinoma on MRI/CT with clinical and radiomic data

In total, 1688 different features were extracted for T2WI, FLAIR, T1WI, DWI, T1WI_CE, and CT respectively for each patient. This feature dataset included shape descriptors. The intensity features included simple first-order statistics and those derived from the gray-level co-occurrence matrix (GLCM), gray-level run-length matrix (GLRLM), gray-level size-zone matrix (GLSZM,), neigh-boring gray-tone difference matrix (NGTDM), and gray-level dependence matrix (GLDM).

针对每位患者，分别针对T2加权成像（T2WI）、液体衰减反转恢复序列（FLAIR）、T1加权成像（T1WI）、弥散加权成像（DWI）、对比增强T1加权成像（T1WI_CE）以及计算机断层扫描（CT）提取了共计1688种不同特征。该特征数据集包含形态描述符。强度特征涵盖简单的一阶统计量，以及源自灰度共生矩阵（GLCM）、灰度游程长度矩阵（GLRLM）、灰度尺寸区域矩阵（GLSZM）、邻域灰度差分矩阵（NGTDM）和灰度依赖矩阵（GLDM）的特征。
