Answer Thursday!
Yesterday’s image was from the soft tissue phase of nuclear scintigraphy, commonly called a bone scan. Today, we’re looking at the bone phase and that dark spot is an important clue!
A bone scan uses an injected radioactive tracer and a special camera to show bone activity. Areas with increased bone remodeling take up more tracer, creating “hot spots” that appear darker in these images.
In this patient, the scan flagged the medial, or inside, aspect of the right hock as an area needing a closer look. It helps tell us where to investigate, but we still need to determine exactly what’s happening.
Next step: X-rays. Now that we’ve narrowed our focus to a specific area, radiographs will let us examine the bone’s structure, further pinpoint the problem, and hopefully identify a way to help this horse.
Stay tuned for next week’s What’s Up Wednesday. We’ll be sharing the X-ray images and giving you a chance to put the clues together! 👀
Diagnostically driven. Patient focused. Getting to the root of the problem. 💙
