What tools does a neurosurgeon use to diagnose brain and spinal cord disorders?

There are many laboratory methods and tests that help the surgeon in the path of diagnosis and surgery, such as the following:

  • Magnetoencephalography (MEG): This method is used to find the cause of seizures and epilepsy.
  • Electroencephalography (brain tape): To create an EEG, the technician places a number of electrodes on the scalp to record the electrical activity of the brain. This method helps to diagnose brain diseases such as inflammation of the brain, tumor and injuries and cerebrospinal injuries.

  • Magnetic resonance imaging or MRI: radio and magnetic waves are used to create accurate images of the nervous system, especially the brain and spinal cord, which is called MRI.

  • Positron emission tomography (PET): often used to detect cancer in the brain and spinal cord.

  • Computed tomography or CT scan (CT): CT scan is a test that uses X-rays and computer imaging technology to create an image of the nervous system and provide it to the surgeon.

  • Angiography: Angiography is used to image blood vessels. To perform angiography, a dye is injected into the patient’s vein, then a specific image of the blood flow system is created using X-rays. This test is used to diagnose vascular disorders of the brain.

  • Examining the cerebrospinal fluid with lumbar puncture: In this method, the surgeon uses a needle inserted into the spine to take samples from the cerebrospinal fluid to check for diseases such as meningitis, leukemia, MS and dementia, etc. to recognize
