Question: Air was formerly used as a contrast medium in imaging the brain in a technique called pneumoencephalography in which air was injected into the cerebral ventricles to enable the imaging of tumors or other abnormalities. Explain why this would work. (This painful and potentially dangerous procedure has been rendered unnecessary by improvements in imaging by CT and MRI.)
Can you please explain this with clear writing,thankyou very much.
