20% energy window centered at 140 keV 128 × 128 matrix 2–5 s/frame for 60 s | 256 × 256 matrix 60-s images | 256 × 256 matrix 150 to 1,000 kcts, depending on body part (Table 2) For limited studies on patients with localized pain, acquisition of at least 1 view to include major joints proximal and distal to the painful site |
↵* Delay is greater for elderly, debilitated, or diabetic patients.
HDP = hydroxymethylene diphosphonate.
