Lu-177-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 Lu-177 and used for clinical imaging and treatment. To our knowledge, Lu-177 had never before been used to label macroaggregated albumin, and our radiopharmacy laboratory at Istanbul University-Cerrahpasa 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 Lu-177-macroaggregated albumin and imaged with SPECT/CT.
