Piloting 18F-FAPI PET/MRI for Applications in Breast Cancer

The patients will be injected intravenously with 2 MBq/kg 18F-FAPI, 60 minutes before the PET/MRI acquisition. The PET/MRI examinations will be performed on a Siemens Biograph mMR (Siemens Healthcare, Erlangen, Germany) with software version VE11P. Static PET will be acquired simultaneously with MRI using two protocols; a one bed position protocol in prone position covering the breast and a whole body 4-5 bed position protocol in supine position covering brain to thighs. Total acquisition time of the breast protocol will be approximately 20 minutes. Total acquisition time of the whole-body protocol will be approximately 30 minutes.
