Although quantitative MRI for articular cartilage
composition shows promise for early detection of
osteoarthritis (OA), large-scale application is hampered
by long scan times if added to routine MRI protocols. We
assessed the performance of a quantitative 3D FSE T2 and
T1rho mapping sequence to diagnose cruciate ligament and
meniscal tears, bone marrow lesions, and cartilage
defects. For anterior cruciate ligament and medial
meniscal tears, diagnostic performance of the 3D FSE
T1rho mapping sequence was good and superior to T2
mapping. This sequence may be used to replace routine
clinical pulse sequences, enhancing scan time efficiency
and potentially accelerating large-scale implementation.
