T2-weighted images are a type of magnetic resonance imaging (MRI) scan that highlights differences in tissue water content. In these images, fluids appear bright, making it easier to identify areas of swelling, inflammation, or other abnormalities. This is particularly useful for diagnosing conditions in the brain, spine, and joints. The technique works by measuring the time it takes for protons in water molecules to return to their equilibrium state after being disturbed by a magnetic field. T2-weighted images are commonly used in clinical settings to assess various medical conditions, providing valuable information for diagnosis and treatment planning.
