CAMRT Radiography Practice Exam

In the Scottie dog representation, what is identified as the eye?

1. Transverse process

2. Pedicle

3. Pars interarticularis

4. Lamina

The correct answer is: Pedicle

The correct choice for identifying the "eye" in the Scottie dog representation of the lumbar spine is the pedicle. In this anatomical illustration, the lumbar vertebrae resemble a cartoon dog, where different parts correspond to specific anatomical structures. The "eye" of the Scottie dog is essentially the pedicle, which is a short, thick bony structure that connects the vertebral body to the posterior elements. The pedicles lie on either side of the vertebral body, and they form part of the vertebral arch. Seen in an oblique view, the position and shape of the pedicles give the appearance of the dog’s eyes. This visual aid helps in understanding the anatomy and orientation of the spine during radiographic assessments and is particularly useful in identifying conditions like spondylolysis when evaluating images.
