Summary

Nuclear medicine studies evaluate gastrointestinal motility. While gastric emptying is the gold standard, assessing fundal and antral function offers clinical value for dyspepsia, though newer methods lack widespread use.

Area of Science:

  • Gastroenterology
  • Nuclear Medicine
  • Medical Imaging

Background:

  • Nuclear medicine provides diverse studies for gastrointestinal (GI) motility evaluation.
  • Gastric emptying scintigraphy is the gold standard for gastric motor function assessment.
  • Current applications often limit analysis to total gastric emptying, overlooking fundal and antral contributions.

Purpose of the Study:

  • To review established and novel scintigraphic techniques for GI motility assessment.
  • To highlight the clinical utility of detailed gastric emptying analysis, including fundal and antral function.
  • To discuss the current status and clinical applications of various GI scintigraphic studies.

Main Methods:

  • Review of existing literature on nuclear medicine studies for GI motility.

  • Focus on scintigraphy for gastric emptying, small bowel transit, and colon transit.
  • Emphasis on clinical relevance and diagnostic value.

    • Main Results:

    • Gastric emptying scintigraphy can provide more detailed functional information beyond total emptying.
    • Assessment of fundal and antral function is clinically valuable for dyspepsia evaluation.
    • Newer scintigraphic methods for small bowel and colon transit are underutilized.

    Conclusions:

    • Nuclear medicine offers valuable tools for comprehensive GI motility assessment.
    • Expanding the application of gastric emptying studies to include regional function can improve patient care.
    • Further adoption of advanced scintigraphic techniques is warranted for broader clinical use.
