Amino Acid Imaging (MET/FET)
Principle:
Disadvantages:
Binding reflects amino acid (i.e. methionine) transport
• Limited usefulness outside brain • Fusion with MRI/CT mandatory • Very limited availability ([ 11 C]methionine)
Advantages:
• High tumor/background ratio (in brain) •Independent from BBB disturbance • Relatively specific for malignancies • [ 123 I]-IMT SPECT widely available
