Imaging at Follow-up
MRI of the brain without and with contrast is recommended during on therapy follow up of a calvarial tumor. (GRADE C, SOR 1.00, very strong recommendation) CT of the head without contrast may provide complementary information at follow up especially as it relates to bony treatment response. CT however does not serve as a primary method of follow up. Contrast-enhanced CT is not recommended for follow up unless MRI is contraindicated.
