A system and method to perform parallel MR imaging are disclosed. The system comprises an MR imaging machine and a probe having at least two MR RF reception coils. Each coil of the probe is operationally connected to a separate receiver channel of the MR imaging machine. The MR imaging machine implements a partially parallel acquisition method to excite precessing nuclear spins, in and around an internal segment of a patient into which the probe is inserted, and to use the coils of the catheter to simultaneously sample a plurality of response signals to form reduced k-space data sets for each of the coils. The plurality of response signals represent nuclear magnetic resonance signals arising from the precessing nuclear spins. The reduced k-space data sets are further processed by the MR imaging machine to generate a full volume dataset of a region in and around the vessel.
