What is a hyder scan?

A Hyder scan is a specialized type of MRI (magnetic resonance imaging) that uses a contrast agent called hydergine, which enhances the visibility of brain activity and blood flow. It is particularly useful in the assessment of neurological conditions, helping to visualize areas of the brain that may be affected by diseases such as Alzheimer's or other forms of dementia. By providing insights into cerebral metabolism and function, a Hyder scan aids in diagnosis and treatment planning.
