[00:00:00]Wait, this X-ray is hiding a dog. And no, I'm not joking. This is called the Scotty dog sign. It appears on an oblique view of your lumbar spine, and it's one of the most iconic findings in radiology. Every part of the vertebrae becomes a part of the dog. The pedacle is the eye. It's round and dense, just like an eyeball on X-ray. The transverse process forms the head. The superior articular process sticks out like the ear. the lamina and spinus process.

[00:00:32]That's the back and the tail. And the legs, the inferior articular process is the front leg. The opposite inferior articular process forms the back leg.

[00:00:43]But here's the part that actually matters clinically. See the dog's neck?

[00:00:48]That's the pars interarticularis.

[00:00:51]And when it breaks from a fracture, it looks like the dog is wearing a collar.

[00:00:56]That's called spondyolyis.

[00:00:59]Save this for your next radiology posting. And if you're a med student, this is definitely coming in your exams.
