Dataset

Please check out MRGen-DB to download our curated dataset, including two parts: radiopaedia_data and conditional_dataset.

For the conditional dataset, we have directly provided our processed data, including the raw image, mask annotations, and text descriptions.

As described in our paper, considering the data privacy concerns of Radiopaedia, we only release the JSON files of this part here. For each case, the format is represented as ./radiopaedia/{patient_id}/{case_id}/{volume_id}/{slice_id}.jpeg, for example, ./radiopaedia/2564/1/MRI_4/1.jpeg. This format allows you to locate the corresponding original volume through the link provided in our json files. After obtaining official authorization from Radiopaedia, you may download the data corresponding to the JSON file on your own. Alternatively, you can send the authorization via email to us ([email protected] or [email protected]) to obtain the download link for the image data in our MRGen-DB.
