Diagnosis of a Brain Tumor
Question: Which methods are used to diagnose a brain tumor?
Answer: The diagnostic process is largely based on radiological examinations.
Main methods used:
• MRI (Magnetic Resonance Imaging)
• CT (Computed Tomography)
• PET
• DSA (Cerebral Angiography)
In addition:
• Functional MRI
• MR Spectroscopy
• Diffusion / Perfusion / DTI MRI
• EEG / MEG
may be used to assess the tumor’s impact on functional brain regions.
The goal is not only to answer “Is there a tumor?” but also to clarify the tumor’s location, type, and surgical planning.
“Approximately 20–40% of brain tumors are metastatic tumors that have spread to the brain from another part of the body. Therefore, blood tests and consultations with other specialties may also be part of the diagnostic process.”
Before your imaging appointment:
- Bring previous MRI/CT CDs and reports.
- Write down a list of medications you use (especially anticoagulants).
- Be sure to mention conditions such as seizures, allergies, or kidney disease (important for contrast-enhanced MRI).
