Back in January I had a wonderful dinner conversation with Efrat Shimron and Eddy Solomon about some of the history of Magnetic Resonance Fingerprinting (MRF) at the ISMRM Workshop on Data Sampling in Sedona, Arizona. There’s so much that our lab never published and both of them suggested that I write some of this up so that others could see how we got to MRF. We’ve had some health issues in my family so I’ve been a bit delayed in writing anything, but today marks the 10-year anniversary of our paper in Nature. This is by far one of the most important papers I’ve ever been a part of. We also got the news last week that Siemens got FDA approval for their MRF product, so the timing is probably right to get some thoughts down as the next crop of new researchers and clinicians start to use this method in clinical situations.
