Figure 5

Qualitative representation of shift between pre-op and post-op MR images. 5A: Sagittal slice of the patient's pre-op image. 5B: Axial Slice of the patient's pre-op image. 5C: Corresponding sagittal slice of the patient's post-op image. 5D: Corresponding axial slice of the patient's post-op image. Cross-hairs in the bottom row represent a point picked on the cortical surface of the patient's post-op image actually lie beneath the parenchyma in the patient's pre-op image due to the presence of brain shift. 5E: Outer edge contour of an axial slice (shown in green) of the patient's post-op image overlaid on the patient's pre-op image.
