Normal computed tomographic features and reference values for the coelomic cavity in pet parrots.

Area of Science:

• Veterinary Radiology
• Avian Anatomy
• Comparative Imaging

Background:

• Growing popularity of pet birds necessitates advanced veterinary diagnostics.
• High-standard imaging procedures are increasingly expected in avian medicine.
• Specialized avian medical practice requires detailed anatomical references.

Purpose of the Study:

• To create an atlas of matched anatomical cross-sections and contrast-enhanced CT images.
• To cover the coelomic cavity in three common psittacine species.
• To support diagnostic imaging in avian veterinary medicine.

Main Methods:

• Performed contrast-enhanced computed tomographic (CT) studies on live birds (macaws, African grey parrots, monk parakeets).
• Acquired both pre- and post-contrast CT scans using a 4-multidetector-row CT scanner.
• Created anatomical cross-sections from frozen cadavers of the same species, sliced at 5-mm intervals.

Main Results:

• Generated matched anatomical cross-sections and contrast-enhanced CT images of the coelomic cavity.
• Identified individual anatomical structures using veterinary literature.
• Reported pre- and post-contrast attenuation values (Hounsfield units) for key coelomic organs.

Conclusions:

• The study successfully provides a comprehensive atlas of avian coelomic anatomy.
• This atlas correlates anatomical cross-sections with contrast-enhanced CT images.
• The resource is valuable for diagnosing conditions in common psittacine species.
