PET/CT
A PET/CT combines a positron emission tomography scanner with a CT in one gantry, so functional and anatomical images line up in a single exam. Oncology and neurology referrals drive most PET/CT volume. When comparing systems, look at the axial field of view, detector technology, time of flight capability, and the CT slice count built into the unit. Reconstruction software and scan time affect how many patients you can fit into a day. Refurbished PET/CT systems can lower the entry cost for independent centers and are regularly financed.
