All patients were instructed to avoid strenuous work or exercise for at least 24 h, and to fast more than 4 h before intravenous injection of 18F-FDG at a dosage of 5.55 MBq (0.15 mCi) per kilogram body weight. The patients then rested in a warm, darkened room for nearly 1 h. After emptying the bladder, an acquisition was performed from mid-thigh to skull base (five to six bed positions, 2 min per bed) using a Siemens Biograph 64 Truepoint TrueV PET/CT scanner. Twenty-nine (82.9 %) patients also underwent a second PET/CT scan 2 to 4 weeks after the steroid-based treatments at a dosage of 40 mg to 50 mg prednisone per day (Table 1 ).
Biograph 64 truepoint truev pet ct scanner
Manufactured by Siemens
The Biograph 64 Truepoint TrueV PET/CT scanner is a medical imaging device that combines positron emission tomography (PET) and computed tomography (CT) technologies. The core function of this equipment is to acquire high-resolution images of the body's internal structures and metabolic processes, providing healthcare professionals with comprehensive diagnostic information.

18 F-FDG PET/CT scan was conducted to assess the response to apatinib. Briefly, patients were instructed to avoid strenuous work or exercise for at least 1 day and fast for >4 h before the 18 F-FDG (0.15 mCi/kg) injection. After injection, patients rested in a warm, dark room for 40-60 min.
68 Ga-NOTA-PRGD2 was synthesised using the method described elsewhere (Zheng et al. 2015) (link). The radiochemical purity of the product 68 Ga-NOTA-PRGD2 exceeded 95%. After intravenous injection of 111-185 MBq (3-5 mCi) of 68 Ga-NOTA-PRGD2, patients were asked to rest for nearly 40 min. The PET acquisitions were performed 1 h after the injection.
The acquisition was performed from skull to midthigh (five to six beds position, 2 min per bed) using a Siemens Biograph 64 Truepoint TrueV PET/CT scanner.
The PET/CT data sets were reconstructed using iterative reconstruction (ordered subset expectation maximum, OSEM) and attenuation correction. The results were measured using the software on the PET/CT system's workstation (TrueD, Siemens Medical Systems) .

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.
