In an oblique lumbar spine view, what structure is represented by the "eye" of the Scotty Dog?

In an oblique lumbar spine view, the "eye" of the Scotty Dog represents the pedicle. This anatomical feature is a crucial part of the vertebra, connecting the body of the vertebra to the transverse process. The Scotty Dog model is a well-known visual mnemonic used in radiology to help identify various structures on an oblique lumbar spine X-ray.

In this imaging technique, the orientation allows for better visualization of specific elements of the vertebrae, and understanding these relationships is vital for diagnosing potential pathologies. The pedicle appears prominently in this view, resembling the eye of the dog, and its assessment is critical in ensuring the integrity of the spinal architecture. Analyzing abnormalities such as fractures or congenital anomalies often involves closely examining the pedicles, thereby reinforcing the importance of recognizing this structure in the context of spinal imaging.
