MAGNETIC RESONANCE IMAGING OF THE NORMAL EYE AND ORBIT OF A SCREECH OWL (OTUS ASIO)

摘要

Magnetic resonance images of a screech owl (Otus asio) were acquired to identify the normal anatomic components of the eye‘and orbit. T1‐weighted, proton‐density, and T2‐weighted images were obtained in the straight sagittal, oblique dorsal, and oblique sagittal planes. Signal intensity for the various orbital structures differed between the three resonance techniques. T1‐weighted images provided the best anatomic detail of ocular and orbital structures. The oblique dorsal and oblique sagittal planes were superior for evaluating the optic nerve in its
