WebA CSF analysis is used to measure different substances in your cerebrospinal fluid. It may include tests to diagnose: Infectious diseases of the brain and spinal cord, including meningitis and encephalitis. CSF tests for infections look at white blood cells, bacteria, and other substances in the cerebrospinal fluid. WebCSF flow dynamics are very important in determining the type of hydrocephalus seen. Phase-contrast MRI is extremely sensitive to CSF flow and provides the potential for non-invasive CSF flow quantification. We studied 20 patients in whom the diagnosis of hydrocephalus was established. The study
