Comparison between FDG an FAMT in terms of T/L ratio in NET lesions and CAR lesions. a T/L ratio of FAMT uptake was significantly lower than that of FDG in the group of NET lesions (p < 0.01). b T/L ratio of FAMT (median 1.80) was slightly higher than that of FDG (median 1.10), but not significant (p = 0.345). FDG 2-[18F]-fluoro-2-deoxyglucose, FAMT L-3-[18F] fluoro-alpha-methyl tyrosine, T/L tumor-to-liver parenchymal, CAR carcinoid tumor, NET neuroendocrine tumor and pheochromocytoma
