UCSF Primary Central Nervous System Lymphoma MRI Dataset

This BIDS-formatted dataset provides multimodal brain MRI data from 150 patients with primary central nervous system lymphoma (PCNSL), including T1-weighted, contrast-enhanced T1-weighted, FLAIR, and ADC sequences. The dataset includes expert-annotated lesion segmentations with radiomic features, along with anonymized clinical data including demographics, diagnosis history, and medications.本数据集采用脑成像数据结构（Brain Imaging Data Structure，BIDS）格式，包含150例原发性中枢神经系统淋巴瘤（primary central nervous system lymphoma, PCNSL）患者的多模态脑部磁共振成像（Magnetic Resonance Imaging, MRI）数据，具体包括T1加权成像、对比增强T1加权成像、液体衰减反转恢复（Fluid-Attenuated Inversion Recovery, FLAIR）序列以及表观扩散系数（Apparent Diffusion Coefficient, ADC）序列。该数据集附带专家标注的病灶分割结果与放射组学特征，同时收录匿名化临床数据，内容涵盖人口统计学信息、诊疗史及用药情况。
