Question

1. MRI scans are utilized more often than CT scans because they are more sensitive and capable of detecting tumors too small to be noted on CT scans.
2. Positron emission tomography (PET) scans are not the most accurate method to diagnose or treat brain tumors. This method may have a role in grading a tumor for prognosis, localizing a tumor for biopsy, and mapping brain areas prior to surgery.
3. An angiogram is the diagnostic tool used for detecting vascular abnormalities, not tissue masses.
4. Functional MRIs may be used to assess the potential clinical outcomes of the tumor.
