The tumor was first identified on contrast-enhanced CT and later confirmed using 68Ga-DOTATATE and 68Ga-NODAGA-LM3 PET/CT. Both tracers demonstrated similar pattern with higher tumor affinity and tumor-to-background ratio using 68Ga-NODAGA-LM3. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
