Patients were instructed to fast for at least 4 h before administrating 18F-FDG. After measuring blood glucose, 18F-FDG was injected into a peripheral vein. One hour later, patients underwent PET/CT imaging from the skull to the pelvis (including a non-contrast, free-breathing, non-gated CT scan). Images were acquired in 3D mode on a Discovery VCT or Discovery RX scanner (GE Healthcare, Waukesha, WI) using well established clinical imaging protocols. The CT scan was acquired using at a tube voltage of 120 or 140 kV and with a low tube current (range 59–80 mAs). Radiation dose was 3.4 ± 0.6 mGy CT dose index volume and 422.4 ± 378 mGy*cm dose length product. Images were reconstructed using a standard soft tissue kernel and with a slice thickness and increment of 1.25 mm. PET/CT and CT images were merged and analyzed using Advantage Window volume viewer software (GE Healthcare, Milwaukee, WI, USA), as previously described12 (link).

Advantage window volume viewer software
Manufactured by GE Healthcare
Sourced in United States
The Advantage Window Volume Viewer software is a tool designed to visualize and analyze medical imaging data. It provides a graphical user interface for interacting with volumetric data, such as that obtained from CT or MRI scans, allowing users to view, navigate, and manipulate the data.

The PET/CT images were visually reviewed using Advantage Window Volume Viewer software (GE-Healthcare, Milwaukee, Wisconsin, United States), providing multiplanar reformatted images of PET alone, CT alone and fused PET/CT. Images were analyzed in consensus by two board‐certified nuclear medicine physicians (YEY and CPA). Physicians were not blinded to the clinical and imaging information of the patients obtained before
18F-NaF PET/CT, but were blinded to the data of revision surgery. Attenuation-corrected PET images as well as fused PET/CT images were used for analysis, using the CT for anatomical correlation. Visual assessment of increased uptake around cage/intervertebral disk space higher than background recorded from the first normal adjacent vertebra was interpreted as positive, even without abnormality on fusion CT. Visual assessment of uptake around cage/intervertebral disk space lower or equal than background recorded from the first normal adjacent vertebra was interpreted as negative. Image data were also quantitatively analyzed by the maximum standardized uptake value (SUV
max) as an index of
18F-NaF uptake, and the ratio between the cage/intervertebral disk space and background recorded from the first normal adjacent vertebra was calculated. For the control group, conventional CT scan was interpreted by a radiologist blinded to the results of
18F-NaF PET/CT.

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.
