Three-Dimensional Spoiled Gradient MRI

**Semantic type:** Diagnostic Procedure

**Definition:** A magnetic resonance imaging modality that uses acquisition in the steady state with semi-random changes in the phase of the radio frequency pulses to produce a spatially independent phase shift. This optimizes the signal-to-noise ratio to provide high resolution and a decrease in the partial volume phenomenon.
