Principles and Clinical Applications of Gradient-Echo Pulse Sequences - Magnetic Resonance Imaging

Puntos clave

• The aim is to summarize the signal formation process of gradient echo sequences from a k-space perspective and organize clinical applications systematically.
• The signal formation process is organized based on k-space principles.
• A classification system is proposed focusing on transverse coherence handling between RF cycles.
• Clinical applications of each gradient echo category are detailed comprehensively.
• Demonstrates the sensitivity of T2* decay to uncorrected magnetic field inhomogeneities and susceptibility effects.
• Provides a structured classification for clinical application that serves as a reference for selecting gradient echo techniques.
