The invention provides a method for performing magnetic resonance imaging, MRI, which exploits prior knowledge of the interactions between electromagnetic fields and spins in the sampled object. This technique is able to provide shorter acquisition times with respect to traditional (Nyquist-Shannon limited) MRI. The method is based on an encoding matrix formalism constructed from the specific knowledge of how every spin would evolve in time depending on their position for a given pulse sequence. This particular previous knowledge has not been fully exploited previously by traditional MRI techniques. Moreover, the method of the invention can be used in combination with other schemes, such as compressed sensing, parallel imaging, or deep learning, for further shortening the MRI scan time.
