Sentinel Node Detection in Head and Neck Malignancies: Innovations in Radioguided Surgery

Figure 1

SPECT/CT to rule out a presumed sentinel node. Anterior (a) and oblique (b) planar static images after 2 hours show drainage to the right neck on the basis of which 3 sentinel nodes were marked. SPECT/CT (c) demonstrates the cranial hotspot located at the base of the tongue in the oropharynx (arrow), due to leakage of the tracer from the injection area. The sentinel nodes are clearly visualized with SPECT/CT (d), while three-dimensional reconstruction (e) shows an anatomic overview of all hotspots.
