Measurement of HU value. A1/A2, signal changes of endplate and bone marrow on MRI scans (corresponding T1W/T2W); B, locate MCs regions in axial plane; C/D, oval ROI of HU value in axial plane with MCs (corresponding endplate/bone marrow); E/F, oval ROI of adjacent vertebra without MCs (corresponding endplate/bone marrow); G, located MCs regions in sagittal CT plane; H, rectangular ROI in sagittal CT plane (small yellow rectangle showed endplate with MCs, big yellow rectangle showed bone marrow with MCs; small white rectangle showed endplate with no MCs, big white rectangle showed bone marrow with no MCs)
