CHGA and carcinoid syndrome: We used this type of PET because it is more sensitive than the In-DTPA-octreotide scan as described by Deppen et al.[7] The patient showed no signs of carcinoid syndrome: serum chromogranin A level was 242.6 μg/L (normal value: 0–100) and urinary hydroxyindoleacetic acid level was 3.2 mg/24 h (normal value: 0–6.9).
