Magnetic Resonance Imaging (MRI): This is an imaging method that uses strong magnetic fields and radio waves to create detailed images of the brain without using x-rays.
Computed Tomography (CT): CT scans combine multiple x-ray images taken from different angles to create cross-sectional images of the brain.
Positron Emission Tomography (PET): PET scans involve injecting a radioactive substance into the body, which emits gamma rays that can be detected by a scanner. This allows visualization of brain activity and function.
