Palpating the Brain with MR Elastography to Detect Raised Intracranial Pressure

John J. Chen, M.D., Ph.D., Mayo Clinic Neuro-ophthalmologist, discusses recent research using MR elastography to detect raised intracranial pressure. The potential for vision loss, that could become permanent, is the main reason for a proper diagnosis of raised intracranial pressure. Mayo Clinic’s previous data lead to a grant to evaluate intracranial pressure using MR elastography. MR elastography may be a way to noninvasively detect increased intracranial pressure which would improve both diagnosis and treatment.
