A phantom study: Should ¹²⁴I‐mIBG PET/CT replace ¹²³I‐mIBG SPECT/CT?

Purpose The isotope 123 I is commonly labeled with meta‐iodobenzylguanidine (mIBG) for imaging of neuroendocrine tumors, such as pheochromocytomas and neuroblastomas. 123 I‐mIBG SPECT/CT imaging is performed for staging, follow‐up and selection of patients for treatment with 131 I mIBG. As an alternative to 123 I, 124 I‐mIBG PET/CT may be used, potentially taking advantage of the superior PET image quality. The purpose of this study was to...
