  • * Data assume 12 h between administration of 90Y and surgery.

  • Estimations assume that reference activity Aref = 3 MBq/kg is administered.

  • Nles. = number of lesions; Aadm = administered activity; ν = signal rate expected on probe in each lesion; νNT = nontumor rate expected on probe in each lesion; Embedded Image = time needed to identify a 0.1-mL residual; Embedded Image = the minimum activity that needs to be administered to have Embedded Image; S = surgery; RT = radiotherapy; PRRT = peptide receptor radionuclide therapy; CT = chemotherapy.
