FIGURE 3.  MRI (A), ¹¹¹In-pentetreotide (B), and ¹²³I-MIBG (C) scans of a patient with metastatic nonfunctioning P-NET demonstrate intense Oct uptake in liver and lymph node metastases and the large primary lesion (A and B, arrows). These findings are in contrast to the virtually negative MIBG scan, showing only partial uptake in 1 metastatic lesion in left liver lobe (C, arrow to right), with rest of tumor lesions being negative; note the cold area (C, thin arrow) in the right liver lobe corresponding to the major metastatic site.
