Abdominal ¹⁸F-fluoro-L-DOPA PET-scan imaging in HI. Focal form (A, B, C): PET-scan localizes accurately the focal lesion. A: Anterior view of a 3 dimensions CT-scan reconstruction fused with PET imaging. B: Transversal view (Fusion PET&CT) of the same patient with a focal form. The pancreatic uptake of the radiotracer is almost exclusively located at the head of the pancreas with a near-complete silencing of the rest of the pancreatic tissue (C: Transversal PET imaging). In a suspected diffuse form, the uptake of the radiotracer appears in the whole pancreas (D: PET, transversal view; E: Pet and 3D CT fusion). Fluoro-DOPA is excreted in the kidneys and the bile, so that liver (C, D, E), kidneys (D, E), ureteras, bladder and diaper (E) appear on the PET imaging.
