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39例淋巴瘤患者的770个病灶的病灶级疗效数据、国际预后指数（IPI，International Prognostic Index）评分以及临床结局数据。本数据集还涵盖病灶的感兴趣体积（VOI，Volume of Interest）掩码与原始影像。病灶VOI掩码采用数字成像与通信医学（DICOM，Digital Imaging and Communications in Medicine）格式，分别在诊断计算机断层扫描（dCT，diagnostic computed tomography）、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，简称PET/CT）影像以及PET/CT采集所得的低剂量CT（lCT，low-dose CT）上手动标注生成。VOI范围内的对应影像同样以DICOM格式提供。涵盖CT、PET-CT及PET影像的病灶掩码可大幅节省其他研究者定位病灶或分析病灶特征所需的时间；病灶疗效结局与患者结局数据，也可为研究者开展病灶治疗响应相关研究提供有力支撑。
