Intraoperative gamma cameras for radioguided surgery: technical characteristics, performance parameters, and clinical applications

Abstract

Several small gamma cameras (SGCs) intended for surgical use are now in development or currently being marketed. In this review, we discuss the characteristics, performance, and clinical use of SGCs which are hand-held and small enough to be easily managed by surgeons during their procedures. We expect that SGCs have the potential to be used more widely in radioguided surgery. As advancing molecular imaging technologies will broaden clinical indications, SGCs will likely be used and integrated with other imaging modalities into numerous types of radioguided surgery in the near future.
