¹⁷⁷Lu-Labeled Macroaggregated Albumin Imaging and Treatment Effect in Patient with Cystic Thyroid Nodule

Abstract

A number of different peptides or antibodies have been labeled with ¹⁷⁷Lu and used for clinical imaging and treatment. To our knowledge, ¹⁷⁷Lu had never before been used to label macroaggregated albumin, and our radiopharmacy laboratory at Istanbul University–Cerrahpaşa made a special effort to do so. We present the case of a 43-y-old man whose cystic thyroid nodule was treated with an intranodular injection of ¹⁷⁷Lu-macroaggregated albumin and imaged with SPECT/CT.
