Leiden team wins challenge for faster MRI scan through artificial intelligence

Researchers from Leiden, in cooperation with Philips, have won a challenge in which international research groups dedicate themselves to accelerating MRI scans with the help of artificial intelligence (AI). They developed an algorithm with which it is possible to use eight times less data than normal and still reconstruct an MRI image of a knee that is almost as good as one using the usual amount of data. In the fastMRI challenge, organised by the Facebook AI research lab and New York University, artificial intelligence specialists were challenged to apply their knowledge to making MRI scans faster and more efficient. The 34 teams taking part were supplied with a raw data set of a few hundred MRI scans of knees. They also received a number of incomplete data sets.
