Gradient echo

A gradient echo is a type of magnetic resonance imaging (MRI) signal used to create detailed images of the body's internal structures. It relies on changing (or "grading") the magnetic field quickly to produce various signal contrasts. This method is faster than traditional MRI techniques and useful for capturing images of blood flow, air spaces, or detecting certain tissue properties. By adjusting the gradient fields, doctors can highlight different aspects of the body's tissues, helping in accurate diagnosis while keeping scan times efficient.
