FIGURE 2.

Patient with metastatic pheochromocytoma. Whole-body maximum-intensity-projection scans of ¹⁸F-MFBG obtained 30–60 min after injection (A), 1–2 h after injection (B), and 3–4 h after injection (C) as against a uniform SUV scale (right bar). Lesions are distinctly seen in the liver at 1–2 h and 3–4 h after injection (B and C; arrows). Fused images show lesions more distinctly in liver (D and E; arrows). Lesion in maximum-intensity-projection image is localized to left iliac bone (F; short arrow).
