After injection of 5 × 106 [18F]FDG-labeled NK-92-scFv(FRP5)-zeta cells into tumor-bearing mice, digital autoradiography showed an increased uptake of radioactivity in HER2/neu-positive tumors at 60 min postinjection; NK-92 cells labeled with [18F]FDG did not result in increased uptake of radioactivity in the tumors on digital autoradiography (67). The gene discussed is ERBB2; the disease is neoplasm.
