Diagnosis

Diagnosis of Glioblastoma Multiform and brain tumors is done is done by utilizing MRI’s, CAT Scans, blood test, lumbar puncture and a biopsy of the growth. Doctors may use a neurological exam to diagnose low grade gliomas.

• Functional MRI: Maps brain activity by valuating the structures of the brain and detecting changes in blood flow
• Perfusion MRI: Identifies parts of the brain with less blood flow, a potential sign of a tumor blocking the path
• Tractography: Visualizes white matter tracts which carry electric signals and sensory information for the central nervous system. These images are uploaded to a neurosurgical navigation system in the operating room to guide the surgeon around critical pathways as the tumor is removed.
• CT Scan to diagnose astrocytomas – some people cannot have an MRI because the magnet interfere with implanted medical devices such as pacemakers etc. CT scans take multiple x-rays and provide doctors with another way to see structures in the brain.
• Biopsy – A biopsy removes cells (not the tumor) from the tumor. Doctors can confirm the sample is cancerous based on the information and pathology which can also determine how aggressive.
