1. A polymodal method for imaging a lesion in a patient comprising:
administering to said patient:
an extracellular contrast medium (ECCM) comprising gadolinium-DTPA, anda lesion-specific contrast medium (LSCM) different from the ECCM, which is enriched in the lesion 10 minutes after administration to said patient and is retained in the lesion for at least 1 hour, wherein the LSCM is 18F-fluorodesoxyglucose (FDG), 18F-dopamine, 18F-L-DOPA, 18F-fluorocholine, 18F-fluoromethylethylcholine, or 18F-fluorodihydrotestosterone subjecting the patient to polymodal imaging wherein at least two different imaging modalities are used to provide at least two different imaging signals which are immediately interpolated by a fusion method of the at least two different imaging modalities and wherein the ECCM and LSCM are applied at the same time or the LSCM is applied with a short time delay of 30 minutes maximum after the ECCM.
