ABSTRACT
In current nuclear medicine practice, imaging is routinely performed either with conventional gamma cameras, nowadays commonly equipped with CT scanners, or with PET/CT scanners. In addition to these large devices, several intraoperative small eld of view (SFOV) portable gamma cameras (PGCs) have become available over the past years for intraoperative imaging. With these devices, high-resolution images of small surface areas can be obtained and local radioactivity distribution patterns can be assessed with a relative short image acquisition time. A PGC aids the surgeon to localise radioactive targets during surgery, and it can also be used to guide certain interventions, such as sentinel node (SN) mapping and biopsy.
