PET Imaging of Solid Tumors by a Novel Tracer, 68Ga-FAPI

"* \[68Ga\] Ga-FAPI-46 Solution for Injection is manufactured at the Karolinska University Hospital Radiopharmacy facilities, for imaging studies with Positron Emission Tomography (PET).~* It is a radiolabelled Fibroblast Activation Protein Inhibitor (FAPI) used for PET of a number of different cancer entities.~* Depending on the labelling yield 50 - 370 megabecquerel (MBq) of \[68Ga\] Ga-FAPI-46 Solution for Injection will be administered intravenously 60 minutes prior to whole-body PET image acquisition."

"* Combined PET and computed tomography (CT) imaging with 68Ga-FAPI-46 will be performed using the same protocol on a Biograph 6 PET/CT scanner (Siemens, Erlangen, Germany) and General Electrics (GE) Discovery 710, Milwaukee, Wisconsin, USA at the Department of Nuclear Medicine, Karolinska Huddinge within 2 weeks before surgery.~* PET/CT imaging will be performed in dynamic mode at one bed position centered over the primary tumor for 45 minutes.~* At 60 minutes post injection, a whole-body PET will be acquired."
