Disclosed herein is a magnetic resonance imaging calibration assembly in particular, for dynamic contrast-enhanced magnetic resonance imaging. An exemplary magnetic resonance imaging calibration assembly according to the present disclosure can comprise a subject receptacle for receiving at least a portion of a subject. The exemplary magnetic resonance imaging calibration assembly can further comprise a plurality of phantom compartments, each of which can contain a calibration phantom with a predetermined known T relaxation time. The plurality of phantom compartments can be attached to the subject receptacle in different ways. For example, according to some exemplary embodiments of the 10 present invention, the phantom compartments are separate compartments attached or fixed onto the subject receptacle. According to other exemplary embodiments, the phantom compartments can be formed at least partially by the subject receptacle. The phantom can be for a T1 calibration making use of its known T1.
