Magic‐angle effect on in vivo T2 mapping of cartilage
V Casula, OP Aro, P Paakkari, S Zbyn… - Proc Int Soc Magn …, 2019 - archive.ismrm.org
Magic-angle effect in T2 relaxation time of knee cartilage was determined in vivo at clinical
magnetic field strength. T2 was measured in healthy volunteer's articular cartilage on a 3 T
clinical scanner at two different orientations of the normal direction of the articular surface
with respect to the main magnetic field. Magic-angle effect produced significant variations in
the T2 values of healthy cartilage (up to 102% difference in deep cartilage), clearly
demonstrating the importance of taking the orientation into account in clinical studies when …
