Brain imaging techniques are methods used to visualize the structure and function of the brain. Common techniques include MRI (Magnetic Resonance Imaging), which provides detailed images of brain anatomy, and CT (Computed Tomography) scans, which use X-rays to create cross-sectional images. These techniques help in diagnosing conditions like tumors, strokes, and other neurological disorders. Another important method is fMRI (functional Magnetic Resonance Imaging), which measures brain activity by detecting changes in blood flow. PET (Positron Emission Tomography) scans also assess brain function by tracking radioactive tracers. Together, these techniques enhance our understanding of brain health and disease.
