What is the difference between a brain scan and an MRI?

A brain scan is a general term that refers to any imaging technique that provides a view of the brain. This can include various scanning methods such as Computed Tomography (CT) scans, Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) scans, Single-Photon Emission Computed Tomography (SPECT) scans, and more. Each technique uses different principles and technologies to visualize the brain but they all provide diagnostic information.

On the other hand, MRI (Magnetic Resonance Imaging) is a specific type of brain scan that uses powerful magnets and radio waves to create detailed images of the brain and other parts of the body. MRI produces high-resolution cross-sectional images, allowing doctors to examine the brain structures, detect abnormalities, and diagnose various conditions, including tumors, stroke, bleeding, and other brain disorders.

In summary, a brain scan is a broad term encompassing various imaging techniques, while MRI is a specific type of brain scan that employs magnetic resonance technology to obtain detailed cross-sectional images of the brain.
