Investigations

A CT scan of the brain is a diagnostic imaging technique used to study the details of the head. CT scan takes a series of X-rays and computes the same to produce detailed images of the head. The procedure is usually done as an outpatient procedure. It usually takes about 15 minutes to complete the scan.

Procedures

Lumbar puncture involves the removal of a small amount of cerebro-spinal fluid that surrounds the brain and spinal cord. The fluid is tested to detect evidence of infection, multiple sclerosis, metabolic diseases, brain hemorrhage or other neurological conditions.
