Fig. 4 A diagnostic 3D T1-weighted sequence of the brain with a water-fat shift of 2 pixels (size 1 × 1 mm2), registered to a planning CT. Left: window-level of the CT scan set to show cortical bone and bone marrow. The cortical bone is bright on CT, dark on MRI (arrows). Right: window-level of the CT scan set to show soft tissue contrast in the brain. The registration of MRI and CT is identical between left and right. The arrow points at the ventricle that appears shifted on MRI relative to CT.
