Gradient-recalled-echo (GRE) techniques in magnetic resonance (MR) imaging have evolved significantly. This overview clarifies their history, implementation differences, and provides a vendor-independent classification and glossary for GRE sequences.

Area of Science:

  • Medical Imaging
  • Physics

Background:

  • Gradient-recalled-echo (GRE) techniques are widely used in magnetic resonance (MR) imaging.
  • Commercial availability from 11 major manufacturers highlights the prevalence of GRE sequences.

Purpose of the Study:

  • To trace the history and nomenclature of GRE techniques in MR imaging.
  • To present a classification scheme and glossary for GRE sequences.

Main Methods:

  • Historical overview of GRE technique development.
  • Comparative analysis of GRE sequence implementations across manufacturers.
  • Development of a vendor-independent nomenclature and classification system.

Main Results:

  • GRE sequences exhibit structural similarities with subtle implementation differences.

  • A proposed classification scheme offers vendor-independent nomenclature.
  • A glossary of common GRE abbreviations and acronyms is provided.

    • Conclusions:

    • Standardized nomenclature and classification enhance understanding of GRE techniques.
    • This work aids in navigating the diverse landscape of commercial GRE sequences.
