Q

Vincek et al VRU 2025-

Using 18 F- Sodium Fluoride and a PET scan:

What % of implants had increased radiopharmaceutical uptake (IRU)?

What % did not?

What had the highest uptake?

What was the main take away?

A
  • 38% had IRU
  • 62% had no IRU
  • Sepsis confirmed in a THR
  • Majority of implants don’t uptake the iosotope and when there is uptake it is associated with septic implants and marked degenerative joint pathology

Q

Welsh et al Vet Surg 2025
