The GEM-handle as convenient labeling strategy for bimodal single-domain antibody-based tracers carrying 99mTc and a near-infrared fluorescent dye for intra-operative decision-making
Intra-operative fluorescence imaging has demonstrated its ability to improve tumor lesion identification.However, the limited tissue penetration of the fluorescent signals hinders the detection of deep-lying or occult lesions.Integrating fluorescence imaging with SPECT and/or intra-operative gamma-probing synergistically combines the deep tissue pe
