Diagnostic Lumbar Puncture

Lumbar puncture, also known as a spinal tap, is performed to collect a sample of spinal fluid or check the pressure of fluid in the spinal cord. Our radiologists will use X-ray imaging to precisely guide the procedure. Your doctor may have requested this procedure to find a cause for symptoms you have been experiencing. Lumbar puncture helps to diagnose problems including:

  • Bacterial, fungal and viral infections, including meningitis, encephalitis and syphilis
  • Bleeding around the brain
  • Cancers involving the brain and spinal cord
  • Inflammatory conditions of the nervous system, including Guillain-Barre syndrome and multiple sclerosis
