Figure 2.

99mTc-hydrazinonicotinyl-tyr3-octreotide (99mTc-HYNIC-TOC) and 131I-metaiodobenzylguanidine (131I-MIBG) single photon emission computed tomography (SPECT)/computed tomography (CT) in a patient with cardiac paraganglioma. Intense 99mTc-HYNIC-TOC, but not 131I-MIBG uptake correlated with the soft-tissue mediastinal mass (arrow) at the root of aorta and pulmonary trunk.
