METABOLIC IMAGING
PET [11C]Methionine (MET)
•
Marker for ACTIVE TUMOR PROLIFERATION AND ANGIOGENESIS (Correlates with Ki-67
expression, proliferating cell nuclear antigen expression and micro vessel density)
•
TRUE TUMOR EXTENSION?
[11C] MET uptake ratios compared with the background is
favourable.
