Pediatric gastrointestinal transit scintigraphy: From esophageal transit to whole-gut transit

Area of Science:

• Nuclear Medicine
• Pediatric Gastroenterology
• Diagnostic Imaging

Background:

• Pediatric gastrointestinal scintigraphy is crucial for diagnosing motility disorders, feeding intolerance, reflux, aspiration, constipation, and postsurgical complications in children.
• It offers physiologic and quantitative data, complementing other diagnostic modalities like endoscopy and manometry.
• This review focuses on various scintigraphic techniques for evaluating pediatric gastrointestinal function.

Purpose of the Study:

• To review the applications and methodologies of pediatric gastrointestinal scintigraphy.
• To provide guidance on patient preparation, study protocols, and data interpretation.
• To highlight the diagnostic value of scintigraphy in managing pediatric gastrointestinal conditions.

Main Methods:

• Review of existing literature on pediatric gastrointestinal scintigraphy.
• Summary of techniques including esophageal transit, gastric emptying, gastroesophageal reflux, and small-bowel/colonic transit scintigraphy.
• Emphasis on practical aspects: patient preparation, radiopharmaceuticals, acquisition, and analysis.

Main Results:

• Scintigraphy provides direct, physiologic assessment of gastrointestinal transit and function in children.
• Detailed protocols and interpretation guidelines are presented for various applications.
• Challenges include limited pediatric normative data, necessitating context-specific interpretation.

Conclusions:

• Pediatric gastrointestinal scintigraphy is a versatile tool for diagnosing functional gastrointestinal disorders in children.
• A structured approach to scintigraphy enhances diagnostic accuracy and guides multidisciplinary care.
• Further development of pediatric normative data would improve the utility of these studies.
