In the overwhelming majority of MRI studies, only the reconstructed images are stored and the raw data that was used during the reconstruction process is lost. However, routine raw data storage would potentially allow imaging studies that are conducted now to benefit from future improved image reconstruction techniques. Unfortunately, the raw data storage requirements are often prohibitive, especially in large-scale population studies. We developed a flexible software tool that achieves high lossy compression of MRI raw data and is able to decompress the data back to the vendor-specific format to allow for retrospective reconstruction using the vendor's reconstruction pipeline.
