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.
