  1. 11. Total body perfusion imaging with 15O-water PET

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anna Åhlström; [2023]
    Keywords : ;

    Abstract : Background Positron emission tomography scanners can be used together with the PET tracer 15O-water to image perfusion in the body. It has mainly been used to image perfusion in the brain and heart. The new total-body PET scanners have a larger axial field-of-view, making imaging of the whole body possible without moving the patient. READ MORE
