Intermediate T2-weighted and PD-weighted FSE images are
commonly used in clinical MRI for detection of joint
abnormalities. There are increasing interests in using
T2 and T1rho as biomarkers for improved diagnosis of
osteoarthritis and related diseases. T2 or T1rho
relaxometry is typically performed in 2D or 3D plane
with inferior resolution compared to anatomical imaging
due to scan time limitations. In this work, we
investigated the use of a single scan to acquire
T2-weighted, PD-weighted anatomy images and relaxometry
map with 3D isotropic resolution of 0.6mm in a
clinically feasible scan time. Both relaxometry map and
anatomical images can be subsequently reformatted to
arbitrary plane for post-analysis and diagnosis.
