Whole-Body PET/CT Imaging Protocol

Whole-body PET/CT images were acquired on a Biograph mCT Flow 20-4R PET/CT scanner (Siemens, Healthcare GmbH, Erlangen, Germany) and a GE Discovery 690 PET/CT scanner (General Electric, Munich, Germany) as previously reported [22 (link),23 (link),24 (link)]. Patients fasted at least 4 h prior to administration of approximately 250 MBq 2-deoxy-2-[¹⁸F]fluoro-D-glucose (2-[¹⁸F]FDG), and emission scan acquisition of the immobilized head and neck, thorax, abdomen, and pelvis started approximately 60 min after intravenous tracer administration. Unless contraindicated, iodine-containing contrast medium (Ultravist 300, Bayer Vital GmbH, Leverkusen, Germany or Imeron 350, 2.5 mL/s, Bracco Imaging Deutschland GmbH, Konstanz, Germany) was administered for diagnostic computed tomography (CT) imaging (100–190 mAs, 120 kV; portal venous phase).

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.
