Normal Computed Tomography Findings of Head in Lovebird (Agapornis Roseicollis)

Background: Computed tomography (CT) scanning is one of the most practical and precise diagnostic imaging methods used to evaluate birds’ heads. Objectives: This study aimed to present normal anatomical data of the head of a lovebird (Agapornis roseicollis) using the CT method. The features of the bird’s head were investigated in terms of bones, joints, muscles, sinuses, and other constituent tissues. Methods: This current retrospective cross-sectional study included carcasses of six adult lovebirds (A. roseicollis) (three males and three females), with an average age of 1–3 years and an average weight of 40–60 g. After preparing the CT images, the head of each parrot was subjected to gross anatomical examination. Results: Reconstructed CT images identified most structures of the lovebird (A. roseicollis) head. The parietal, mandibular, occiput, maxillary, preimaxillary, palatine, pterygoid, quadrate, temporal bones, epithelial membranes, external ear canal and bony labyrinth, ossicles, and entoglossal bones, different parts of the infraorbital sinus, brain hemispheres, and various parts of the eyeball and conchae of the nasal cavities were examined on the CT images. The results related to the CT evaluation and anatomical examination of the lovebird’s (A. roseicollis) head demonstrated a high correlation. Conclusion: The study’s results can be employed as a reference and a suitable atlas for identifying anatomical features, examining different species of lovebirds (A. roseicollis), teaching anatomy, interpreting CT scan images, performing clinical examinations, and treating this type of parrot.
