99mTc-3PRGD2 SPECT/CT and planar imaging were performed at 1 month after surgery and 1 to 3 days before RAI treatment using a dual-head gamma-camera (Discovery NM/CT 670 pro; GE Healthcare, Milwaukee, USA) with low-energy high-resolution collimators and a 20% energy window centered on 140 keV. The SPECT and coregistered spiral CT were performed at 40–60 min post injection of 740–1110 MBq (20–30 mCi) of 99mTc-3PRGD2. SPECT scan (matrix 128 × 128 pixels, zoom 1.0, 30 s/frame/6°) of the neck and chest was performed with the patients’ arms raised above their head, followed by CT scan (120 kV, 160 mAs) with the same range of SPECT. The speed of whole-body planar scan (matrix 256 × 1024 pixels) was set at 18 cm/min. The imaging of each patient was reconstructed and analyzed using Xeleris 3.0 workstation (GE Healthcare).

All patients underwent classic 99m Tc-3,3-diphosphono-1,2-propanedicarboxylic acid bone scintigraphy after intravenous injection of a mean (6SD) activity of 840 6 100 MBq (range, 590-950 MBq), followed by SPECT/CT imaging of both foot and ankle at 5.4 6 0.9 h (range, 3.8-7.8 h) after tracer injection.
SPECT/CT (Discovery NM/CT 670; GE Healthcare) images were acquired using a high-resolution low-energy collimator with auto contour rotation mode (15 s/frame; 60 views over 360°; stepand-shoot mode, matrix size, 128 • 128; zoom factor, 1.00) and a 15% energy window centered on 140 keV. Helical CT acquisitions used a voltage of 120 kV, a current of 90 mA, a slice thickness of 0.625 mm, and a 512 matrix for reconstruction. For SPECT image reconstruction, we applied ordered-subset expectation maximization with 2 iterations and 10 subsets, using a point-spread-function recovery "Evolution for Bone" algorithm and CT for attenuation correction on a Xeleris 3.0 workstation (GE Healthcare).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
