It was also shown that these drugs wereeffective in radionuclide tumor imaging: all patients demonstrated anaccumulation of the investigated compounds in HER2-positive tumors.Additionally, in one case, [68Ga]Ga-ABY-002 allowed musclemetastasis (quadriceps) to be detected, which was not identified by 18F-FDGPET. Here, ERBB2 is linked to neoplasm.
