By using radio waves and magnetic fields to take pictures, MRI scan provides very high quality of a cross-sectional slice and lengthwise slices of the brain and thus providing the better and detail image of location of tumor and the surrounding structures. It is one of most likely early test ordered by a doctor to diagnose tumors, strokes, aneurysms, neurological diseases and other brain abnormalities and the blood vessels around the brain.

3. Spinal tap (lumbar puncture)
A spinal tap is a procedure performed when a doctor needs to look at the cerebrospinal fluid (also known as spinal fluid), by inserting a thin needle between two vertebrae in your lower back to extract a sample.
