Abstract

Abstract

En 中文
[18F]fluoro-L-α-methyltyrosine ([18F]FAMT) has been reported as a positron-emission tomography (PET) probe that has high specificity for L-type amino acid transporter 1 (LAT1), which is overexpressed in various malignant tumors. However, [18F]FAMT showed rapid washout from the tumor and high retention in the kidney. This study aimed to develop and evaluate a novel LAT1-targeting PET probe, [18F]FAMT-OMe, and compare its performance with [18F]FAMT in glioma xenograft mice.
