We are sharing a collection of voluminous, expertly curated, and rigorously deidentified data sets for machine learning research on accelerating MRI.

The fastMRI dataset includes:

  • raw data from 1,500 fully sampled knee MRIs
  • DICOM images from 10,000 clinical knee MRIs
  • raw data from nearly 7,000 fully sampled brain MRIs
  • raw data from 312 T2-weighted and diffusion-weighted prostate MRIs
  •  NEW  raw data from 300 radial dynamic contrast-enhanced breast MRIs plus GRASP reconstruction code

The fastMRI project began as a collaborative partnership between CAI2R and Meta AI Research (formerly Facebook AI Research) to accelerate research on machine learning image reconstruction.
