T2-weighted imaging is a type of magnetic resonance imaging (MRI) technique that highlights differences in tissue water content. In this imaging method, fluids appear bright, making it useful for identifying abnormalities such as tumors, inflammation, or edema. T2-weighted images are particularly effective for visualizing soft tissues in the body. This imaging 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 pulse. The resulting images provide valuable information for diagnosing various medical conditions and guiding treatment decisions.
