Gradient - Moment 09 May 2026

GMN, also known as , involves adding extra gradient pulses (lobes) to a pulse sequence to ensure that moving spins do not accumulate a net phase by the time the echo is formed.

: Returns high signal intensity to bright, moving fluids, making them appear "bright" and uniform on T2-weighted images. Key Concepts in "Moment 09" Gradient - Moment 09

: Prevents "ghost" artifacts in the phase-encoding direction caused by moving blood or CSF. GMN, also known as , involves adding extra
