Cardiac Radiographic Measurements in Ferrets Using the OsiriX MD Programme

Area of Science:

• Veterinary Radiology
• Comparative Cardiology
• Small Mammal Medicine

Background:

• Assessing cardiac size in ferrets using radiography is crucial for diagnosing heart disease.
• Existing methods like the vertebral heart scale (VHS) require adaptation for species-specific anatomy.

Purpose of the Study:

• To adapt the vertebral heart scale (VHS) for ferrets.
• To develop and validate new radiographic tools for assessing normal heart size in ferrets.
• To investigate potential sexual dimorphism in cardiac measurements.

Main Methods:

• Prospective study involving 40 healthy pet ferrets (Mustela putorius furo).
• Radiographic measurements were taken from right lateral, left lateral, ventrodorsal, and dorsoventral projections.
• Utilized OsiriX MD software for measurements, including adapted VHS, sternebral heart scale (SHS), and novel cardiac area measurements (AREA-AXIS, AREA-POL).

Main Results:

• Significant sexual dimorphism was observed in most cardiac measurements.
• Established normal ranges for VHS, SHS, and cardiac area measurements in male and female ferrets.
• Demonstrated strong positive correlations between VHS and SHS, and between cardiac area measurements and cardiac dimensions.

Conclusions:

• The adapted VHS, SHS, and cardiac area measurements are reliable tools for assessing cardiac size in ferrets.
• These methods facilitate quicker and more effective radiographic evaluation of ferret heart size.
• The findings highlight the importance of considering sex in cardiac assessments of ferrets.
