IPD Brain

<pre>The IPD-Brain Dataset is a comprehensive collection comprising 547 high-resolution H&amp;E stained slides from 367 patients, aimed at advancing the study of glioma subtypes and immunohistochemical (IHC) biomarkers. This dataset, one of the largest of its kind in Asia, is especially notable for its focus on the diverse demographics of the Indian population. Each slide is scanned at a magnification of 40x and includes detailed clinical annotations in a xlsx file such as patient age, sex, radiological findings, diagnosis, CNS WHO grade, and IHC biomarker status, which covers IDH1 R132H, ATRX, p53, and the proliferation index Ki67. Open for use and governed by ethical guidelines, the IPD-Brain Dataset is designed to facilitate a wide range of applications, from training machine learning models to exploring regional and ethnic variations in disease.A higher resolutions version of this dataset (upto 40x magnification) can be downloaded from data foundation, please follow the following link: https://datafoundation.iiit.ac.in/dataset-versions/cb5917e1-6e56-4984-b6d1-f91d52ccd36c.</pre>

IPD-Brain数据集是一套综合性数据集，包含来自367名患者的547张高分辨率苏木精-伊红（H&E）染色切片，旨在推动胶质瘤亚型及免疫组化（IHC）生物标志物的相关研究。该数据集作为亚洲同类规模最大的数据集之一，其突出亮点在于聚焦印度人群的多样化人口统计学特征。每张切片均以40倍放大倍率完成扫描，且配套包含xlsx格式的详细临床注释信息，涵盖患者年龄、性别、影像学检查结果、诊断结论、中枢神经系统世界卫生组织（CNS WHO）分级，以及包括IDH1 R132H、ATRX、p53与增殖指数Ki67在内的免疫组化生物标志物状态。本数据集遵循伦理准则且对外开放，旨在支撑多元应用场景，从机器学习模型训练到探索疾病的区域与种族差异。
本数据集的更高分辨率版本（最高可达40倍放大倍率）可从数据基础（Data Foundation）平台下载，请访问以下链接：https://datafoundation.iiit.ac.in/dataset-versions/cb5917e1-6e56-4984-b6d1-f91d52ccd36c。
