↵* 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;
= time needed to identify a 0.1-mL residual; 
= the minimum activity that needs to be administered to have 
; S = surgery; RT = radiotherapy; PRRT = peptide receptor radionuclide therapy; CT = chemotherapy.
