Peter’s latest publication is on standardization of SPECT/CT dosimetry following radioembolization with yttrium 90 microspheres by investigating the dose differences due to different self-calibrations and mass density assignments in the non-compartmental and local deposition methods. A practical mean correction method was introduced that permits dosimetry in images where the quality is compromised by patient motion and partial volume effects.
