Fig. 6

SPECT and SPECT-CT images in the transverse plane representing the anatomical structure of the head and neck phantom; images a and b show two superficially low activity uptake simulated SLNs in gamma and hybrid modes (0.1 and 0.2 MBq, respectively). Images c and d show two deeper suited, higher activity uptake simulated SLNs in gamma and hybrid modes (0.5 and 1.0 MBq, respectively). Images e and f show the thyroid level SPECT and SPECT-CT images in the neck region (15 MBq)
