CT, PET-CT and PET for lymphoma response study

The data include lesion-level response data for 770 lesions from 39 lymphoma patients, IPI scores, and clinical outcome data. The data set also includes VOI masks for lesions and the original images. Lesion VOI masks (in DICOM) were manually set up on diagnostic computed tomography: dCT, 18F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) images: PET/CT, and low-dose CT from PET/CT acquisitions: lCT. The corresponding images within the VOI were also provided (in DICOM). Lesion masks from images (CT, PET-CT and PET) will save much time for other researchers to localize the lesions or analyze lesion features; the lesion response outcome and the patient outcome can also facilitate other researchers on their work in lesion treatment response research.

本数据集包含来自39例淋巴瘤患者的770个病灶的病灶级疗效响应数据、国际预后指数（International Prognostic Index, IPI）评分以及临床结局数据。本数据集同时涵盖病灶的感兴趣体积（Volume of Interest, VOI）掩膜与原始影像。
上述病灶VOI掩膜均以DICOM格式存储，由研究人员手动标注于三类影像：诊断计算机断层扫描（dCT）、18F-氟代脱氧葡萄糖正电子发射断层扫描-计算机断层扫描（FDG-PET/CT）影像（PET/CT），以及PET/CT采集流程中获取的低剂量计算机断层扫描（lCT）。该VOI范围内的对应影像亦以DICOM格式一并提供。
本数据集提供的病灶掩膜可大幅节省其他研究者定位病灶或分析病灶特征的时间；病灶疗效响应结果与患者结局数据，也可为开展病灶治疗响应相关研究的同行提供重要支持。
