Figures
- Fig 1.
A and C, Postcontrast SPGR image for reference MRI (C) shows new enhancement along the right anterior limb of the internal capsule, which was not present on comparison postcontrast SPGR (A). B and D, This area shows increased CBV on the concurrent DSC color map (D) compared with the prior DSC color map (B). The appearance was most suggestive of tumor progression, and the management plan was altered accordingly. Susceptibility artifacts are seen along the previous resection cavity in the right temporoparietal region on all images.

Pie chart shows the effect of the addition of perfusion imaging on treatment-team confidence in their chosen management plan.
- Fig 3.
Bar graph shows the frequency of the perceived usefulness of perfusion imaging in these study subjects.
- Fig 4.
Bar graph shows the relative frequencies that specific perfusion techniques were thought most useful by NRs and the treatment team.
