From: Femoral-head vascularity after hip surface arthroplasty
Preoperative bone scintigraphy image of a patient who underwent resurfacing of both the hips (a); postoperative image at 6 months after surgery (b). The right femoral head showed 116% of the preoperative uptake, whereas the left showed 74% of the preoperative uptake (after correction for attenuation). Both resurfaced heads were categorized as showing preserved vascularity
