A Novel Restraining Device for Small Animal Imaging Exams: Validation in Rabbits

الملخص EN

Objective.

To develop, validate, and patent a Restraining Device for Small Animal Imaging Exams (RDSAIE) that allows exams to be comfortably conducted without risks to animals and professionals.

Methods.

A RDSAIE with a mobile cover and shelf was built with transparent acrylic material.

A total of six anesthetized rabbits were used to perform the following imaging exams of the skull: Cone Beam Computed Tomography, Magnetic Resonance Imaging, and Scintigraphy.

Results.

The device showed great functionality and full visibility of the animal behavior, which remained fully stabilized and immobilized in either the horizontal or vertical position without the need for a person to remain in the test room to assist them.

The procedures were performed without difficulty, and images of good resolution and without artifacts were obtained.

Conclusion.

The RDSAIE is comfortable, safe, efficient, and ergonomic.

It allows the easy placement of animals in different body positions, including the vertical, the maintenance of postural stability, and full visibility.

It may be constructed for animals heavier than 4 kg and it is adaptable for translational studies in anima nobile.
