T1rho-weighted MR imaging has recently been proposed as
an attractive biomarker to existing conventional
morphological MRI methods, and enables us to detect
early cartilage degeneration in early osteoarthritis
patients before appearing morphological change. However
the factors affecting the T1rho mapping such as MR
sequences and operator-dependent manual cartilage
segmentation is not well understood. The objective of
this study was to investigate the difference of T1rho
profiles between spoiled gradient echo (SPGR) and
balanced steady state free precession (b-FFE) sequences.
