Figure 2.

After 2 cycles of ¹⁷⁷Lu-DOTATATE peptide receptor radionuclide therapy, the patient received ⁹⁰Y-DOTATATE therapy (single cycle, dose = 3.4 GBq). Post ⁹⁰Y-DOTATATE Bremsstrahlung imaging with whole-body planar and single photon emission computed tomography-computed tomography scans (a and b) and post ⁹⁰Y-DOTATATE regional positron emission tomography–computed tomography scan (c) demonstrated good tracer uptake of ⁹⁰Y-DOTATATE (grade = 3) in liver lesions (arrows). No major adverse effect was seen after ⁹⁰Y-DOTATATE peptide receptor radionuclide therapy in this patient
