Premise: Phase contrast magnetic resonance imaging (PC-MRI) is a specific type of magnetic resonance imaging used primarily to determine flow velocities. PC-MRI can be considered a method of Magnetic Resonance Velocimetry. Since modern PC-MRI is typically time-resolved, it can also be referred to as 4D imaging (three spatial dimensions plus time).
Hypothesis: The following words, such as magnetic, resonance, phase, imaging, and contrast, each represent one of the letters in the acronym "PC-MRI".
