Summary of 10 Major Medical Datasets: Covering Question Answering/reasoning/real Clinical Records/ultrasound Images/ct Images...

With the deep integration of artificial intelligence technology in the medical field and the continuous innovation of medical imaging technology, medical data, as the key to unlocking the mysteries of life, is accumulating and growing at an explosive rate. It has broken through the boundaries of traditional medical research and brought revolutionary changes to disease diagnosis and treatment and health management.
As medical research moves from experience-driven to data-driven, the iteration speed of basic research tools has gradually slowed down.The quality of medical data sets has become a core factor in determining whether a model can move from theoretical conception to clinical practical application.High-quality medical data can not only accurately capture disease characteristics, but also provide reliable support for the formulation of personalized medical plans.
The construction of a medical data set is by no means a simple listing of cases.Compared with general data collection, the acquisition of medical data needs to strictly follow ethical standards to ensure patient privacy and data usage compliance.In order to ensure the scientificity and effectiveness of the data, it is necessary to standardize the data collection process, reasonably allocate training sets, validation sets and test sets, and establish a dynamic update mechanism to regularly add new data to adapt to changes in the disease spectrum and the development of diagnosis and treatment technologies. In the face of complex medical tasks such as disease diagnosis, drug development, and health prediction, when constructing a data set, it is necessary to deeply analyze the needs of various fields, integrate multimodal information, simulate real clinical scenarios, and provide practical learning samples for model training.
In short, in the era of precision medicine, the demand for high-quality medical data sets in the entire medical community has grown explosively.HyperAI has compiled a series of extremely valuable and widely used medical data sets for everyone, covering multiple medical professional fields such as cancer, heart, bone X-ray, etc.Some of them come from top medical schools and authoritative medical institutions.

Medical Dataset Summary
1 JMED Chinese real medical data dataset
Download address:https://go.hyper.ai/4jJTa
The JMED dataset is a new dataset based on the distribution of real-world medical data. It was built by the Citrus Team in 2025. The dataset is derived from anonymous doctor-patient conversations in JD Health Internet Hospital and is filtered to retain consultations that follow a standardized diagnostic workflow. The initial version contains 1k high-quality clinical records covering all age groups (0-90 years old) and multiple specialties. Each question includes 21 answer options.
Unlike existing datasets, JMED closely simulates real clinical data while facilitating effective model training. Although based on real consultation data, it is not directly derived from actual medical data, so the research team can integrate the key elements required for model training.
2 MedQA Medical Text Question Answering Dataset

This dataset is designed for fine-tuning the HuatuoGPT-o1 medical language model to improve its performance in complex medical reasoning tasks. The construction of the dataset relies on GPT-4o, which ensures the accuracy and reliability of the data by searching for verifiable medical questions and verifying the answers using a medical verifier.
4 ROCOv2 Radiology
Multimodal medical image dataset
Estimated size:17.29 GB
Download address:https://go.hyper.ai/xs4zS
ROCOv2 (Radiology Object in COntext Version 2) is an innovative multimodal medical image dataset that combines radiology images with related medical concepts and descriptions. This dataset extracts radiology images and related medical concepts and descriptions from the PMC Open Access subset, and improves concept extraction and filtering based on the ROCO dataset.
The dataset contains 79,789 radiology images, covering a variety of clinical modalities, anatomical regions, and orientations (for X-rays), each with a corresponding medical concept description. It can be used to train image annotation models, multi-label image classification, pre-training of medical domain models, deep learning model evaluation, image retrieval, and caption generation, etc.
