    Area of Science:

    • Nuclear Medicine
    • Gastroenterology
    • Medical Imaging

    Background:

    • Nuclear medicine employs tracer methodology for clinical diagnosis.
    • Radioisotope-labeled compounds serve as tracers to assess regional tissue and organ function.
    • Gastrointestinal diseases require accurate functional assessment for diagnosis and management.

    Purpose of the Study:

    • To review nuclear medicine procedures for diagnosing gastrointestinal diseases.
    • To emphasize the evaluation of the gastrointestinal tract's functional aspects.
    • To present practical applications based on clinical experience.

    Main Methods:

    • Gastric mucosal scintigraphy for Meckel's diverticulum diagnosis.
    • Measurement of esophageal, gastric, and intestinal transit times.
    • Breath analysis techniques for lactose absorption and bacterial deconjugation of bile salts.
    • Detection of portocaval shunts.

    Main Results:

    • Nuclear medicine offers valuable insights into gastrointestinal function.
    • Specific procedures effectively diagnose conditions like Meckel's diverticulum.
    • Functional assessments aid in evaluating motility disorders and malabsorption.

    Conclusions:

    • Nuclear medicine provides essential functional data for gastrointestinal disease diagnosis.
    • The described techniques offer a comprehensive approach to evaluating the GI tract.
    • Further application of these methods can improve patient outcomes.
