Ultrasonographic measurement of the pancreatic body. Its significance in measuring the normal pancreas

Area of Science:

• Medical Imaging
• Gastroenterology
• Pancreatic Diseases

Background:

• Pancreatic size is a key indicator in diagnosing various gastrointestinal conditions.
• Establishing normal pancreatic dimensions is crucial for accurate disease detection.
• The smallest corpus diameter (SCD) offers a specific metric for pancreatic assessment.

Purpose of the Study:

• To determine the normal range for the smallest pancreatic corpus diameter (SCD) in adults.
• To identify a threshold value of SCD indicative of pancreatic enlargement.
• To assess the diagnostic utility of SCD in a non-pancreatitis patient cohort.

Main Methods:

• Retrospective analysis of pancreatic imaging studies.
• Measurement of the smallest corpus diameter (SCD) in 172 patients.
• Exclusion of patients with clinical suspicion of pancreatitis.

Main Results:

• In 96% of patients, the smallest pancreatic corpus diameter (SCD) measured less than 12 mm.
• A smallest pancreatic corpus diameter (SCD) greater than 16 mm was observed.
• This elevated SCD is considered characteristic of general pancreatic enlargement.

Conclusions:

• A smallest pancreatic corpus diameter (SCD) below 12 mm is normal in the absence of pancreatitis.
• An SCD exceeding 16 mm strongly suggests pancreatic enlargement.
• SCD measurement is a valuable tool for diagnosing pancreatic conditions.
