Description
Brendan Eck and co-authors test, in 2024, whether a scanning method for muscle fat gives the same answer across hospitals and machine brands. The method estimates fat fraction inside thigh muscle from a special MRI sequence and could serve as a marker of muscle quality. Patients were scanned ten years after knee ligament surgery, across three sites and two vendors.
Scanning was harmonized and analysis centralized. Phantom tests picked the most stable algorithm, and a new correction step fixed scaling errors seen on some machines. Traveling volunteers checked consistency in people. The setup aims to compare operated and unoperated legs credibly in a long-term multicenter follow-up.
