Advanced Radiologic Imaging
Brain tumors can be difficult to diagnose. Following a complete medical history and neurological examination, your physician may order a CT (computed tomography) scan or a MRI (magnetic resonance imaging). CT and MRI use computer graphics to create an image of the brain.
Other advanced radiologic imaging may also be recommended, including:
- Spectroscopy is a type of MRI that looks at the tumor cell activity as compared to normal cell activity.
- Stealth MRI scans provide additional information on the precise location and margins of the tumor.
- Functional MRI scans are used to determine how close tumors are to the critical structures of the brain that may control such functions as speech, movement, vision and memory.
- PET scans (positron-emission tomography) provide useful information regarding the brain tumor's metabolic activity.
- MRI Angiogram/CT Angiogram scans enable physicians to understand the blood supply to the tumor and the effect of the tumor on normal blood vessels.
- Diffusion Tensor Imaging, Perfusion MRI and Diffusion MRI are other advanced scans that may be useful in diagnosis or at follow-up after treatment.
