From: Simultaneous 166Ho/99mTc dual-isotope SPECT with Monte Carlo-based downscatter correction for automatic liver dosimetry in radioembolization

Fig. 6

Fused 166Ho-only SPECT/CT (left), 166Ho-reconstruction SPECT/CT from dual-isotope acquisition (middle), and corresponding 99mTc-stannous phytate reconstruction SPECT/CT from a dual-isotope acquisition (right) in a patient. Visual assessment of the images by two nuclear medicine physicians shows no differences and the 99mTc-stannous phytate SPECT/CT shows a negative correlation (no uptake in tumor tissue, only uptake in healthy liver tissue)
