FIGURE 7.  CT (A), ¹¹¹In-pentetreotide (B), and ¹²³I-MIBG (C) images of a patient with advanced functioning EC cell carcinoid disease show multiple metastases to liver and intense uptake of both tracers. Additional site of uptake (B, left arrow) belongs to right kidney. MIBG scan depicts another hepatic lesion (C, upper arrow) obscured in pentetreotide imaging by physiologic splenic uptake. One metastatic pelvic bone lesion (B and C, arrows to lower right) is also better visualized in the MIBG scan.
