Original publication title: Decreased radiopharmaceutical uptake (photopenia) in delayed phase scintigraphic images in three horses.

Plain-English summary
This study looked at three horses that had issues with their bones, specifically septic osteitis (an infection in the bone), bone sequestrum formation (where dead bone tissue forms), or thrombosis in their lower limbs (a blood clot). In these horses, a special imaging test showed decreased uptake of a radioactive substance in the affected legs, which is known as photopenia. This finding could suggest that there is a lack of blood flow to the area, which can help veterinarians make decisions about treatment and understand the likely outcome for the horses. The study highlights that while photopenia is more commonly seen in people, it can also be important in diagnosing and managing similar conditions in horses.
Abstract
Decreased radiopharmaceutical uptake, photopenia, in delayed phase scintigraphic images is recognized in people but has only been reported rarely in horses. We describe three horses with septic osteitis, bone sequestrum formation, or distal limb thrombosis that had photopenia of the affected extremity. Photopenia may indicate the presence of ischemia and can be used to facilitate clinical decision making and prognosis assessment
