Imaging modalities have an inherent contrast resolution intrinsic to the modality itself, e.g. MRI, but this baseline resolution is commonly further modified by the tweaking of scan parameters and/or the use of contrast media.

Contrast resolution in radiology refers to the ability of any imaging modality to distinguish between differences in image intensity. The inherent contrast resolution of a digital image is given by the number of possible pixel values, and is defined as the number of bits per pixel value.
