1. A method for spectrally imaging an organ during an image-guided intervention, comprising:
displaying a first image modality of a contrast-enhanced organ based on at least one first spectral scan of the contrast-enhanced organ;
receiving a selection of a region of interest within the displayed first image modality;
obtaining at least one second spectral scan of the contrast-enhanced organ;
obtaining at least three second image modalities;
determining a contrast value over the region of interest for each of the at least three second image modalities, the at least three second image modalities being based on the at least one second spectral scan;
selecting from the at least three second image modalities the second image modality with the largest contrast value; and
displaying the selected second image modality to provide a dynamic adaptation of the displayed second image modality such that a time interval available for guiding the image-guided intervention, before washout of a contrast agent, is prolonged.
