Normal pancreatic thickness values in healthy children: an MRI study

Area of Science:

• Radiology
• Pediatric Imaging
• Gastroenterology

Background:

• Limited data exists for normal pancreatic thickness on CT and MRI.
• Ultrasound (US) has established normal values, but cross-sectional imaging requires defined metrics.
• Accurate pancreatic measurements are crucial for identifying parenchymal changes.

Purpose of the Study:

• To define normal pancreatic thickness measurements across different anatomical regions using MRI.
• To provide objective reference values for assessing pancreatic parenchymal thickness.
• To aid in the diagnosis of pancreatic diseases and chronic pancreatitis atrophy.

Main Methods:

• Retrospective analysis of 162 pediatric abdominal MRI examinations.
• Exclusion of patients with pancreatic or chronic gastrointestinal inflammatory diseases.
• Measurements of pancreatic thickness obtained from T2-weighted MRI sequences.

Main Results:

• Mean pancreatic thickness measurements were established for the head, neck, body, and tail.
• Positive correlations were found between pancreatic thickness and patient age, height, weight, and BMI.
• Interobserver agreement for measurements ranged from moderate to strong across anatomical regions.

Conclusions:

• Established normal pancreatic thickness ranges via MRI in pediatric patients.
• Pancreatic thickness is positively associated with anthropometric factors and age.
• These findings enhance diagnostic accuracy for radiologists evaluating pancreatic conditions.
