"A Brain Image"

A brain image is a visual representation that shows the structure or activity of the brain. Medical imaging techniques like MRI (Magnetic Resonance Imaging) and CT scans use powerful magnets or X-rays to create detailed pictures of the brain's anatomy. Functional imaging methods, like PET scans and fMRI, capture changes in blood flow or activity, helping to understand how different parts of the brain function during specific tasks. These images help doctors diagnose conditions, plan treatments, and research how the brain works, providing important insights without invasive procedures.
