Table 2 Comparison of the extent of non-cystic BMLs (n = 200) as semiquantitatively evaluated using intermediate-weighted (IW) fat-suppressed (fs) and Dual Echo Steady-State (DESS) sequences

From: Semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts of the knee at 3T MRI: A comparison between intermediate-weighted fat-suppressed spin echo and Dual Echo Steady State sequences
