1. A non-transitory storage medium storing instructions executable by an electronic data processing device to perform a method including: identifying a magnetic resonance imaging sequence defined by an imaging protocol, type of tissue to be imaged, and parameter values for a set of parameters of the imaging protocol; computing a contrast signal score for the magnetic resonance imaging sequence respective to a contrast type to be scored using a scoring equation; determining a contrast type for the magnetic resonance imaging sequence based on the computed contrast signal score; operating a magnetic resonance imaging (MRI) device using the magnetic resonance imaging sequence to generate a magnetic resonance image; and labeling the magnetic resonance image with the determined contrast type; wherein the scoring equation is: score ⁡ ( p ) = ∂ S ⁡ ( p ) ∂ p · p S ⁡ ( p ) where score (p) is the contrast signal score for the contrast type to be scored and S(p) denotes the signal generated by the magnetic resonance imaging sequence as a function of a characteristic p whose variation gives rise to the contrast type to be scored, the characteristic p including at least one of a T 1 relaxation time of imaged tissues, a T 2 relaxation time of images tissues, blood velocity, and exogenous contrast agent concentration.
