Explora fdg4 synthesis module

The equipment used is the following: Germany Siemen's company Biography 16 sensation imager, PET: advance PET scanner, 39-ring detector, and CT: light speed 16-row spiral CT.
RDS-Eclipse ST cyclotron from Siemens, Germany; Explora FDG4 synthesis module from Siemens, Germany; TLC system from Bioscan, USA; HPLC from Grace Alltech, USA; Flow-Count Radio-HPLC detector system from American Bioscan Company; and Capintec Corporation CRC-15R/PET activity meter.

The PET/CT imaging instruments used were Biographym CTx PET/CT scanners (Siemens, Munich, Germany), the tracers were 18 F-FDG with radiochemical purity >95%, the synthesis equipment was the Siemens Eclipse RD accelerator and the Explora FDG 4 synthesis module was used. Before the tests, the patients fasted 6 h with fasting blood sugar <8.1 mmol/L, rested in a resting room for 15 min before injection, then took 18 F-FDG intravenously at a dose of 0.15 mCi/kg, and then rested calmly for 60 min for image capture. The scanning range was from the top of the skull to the upper part of the femur, and the scanning direction was from the pelvic cavity to the head. First, a CT scan (120 kV, 200 mA, scanning layer thickness of 3.75 mm) was performed, and then PET 3D acquisition. The acquisition speed was 2 min/bed, with a total from 6 to 7 beds. After acquisition, the image was rebuilt iteratively and the data were passed into the MMWP image post-processing workstation (Siemens, multi-modality workstation, Germany).
