An imaging probe and method and an MRI system utilizing the same are presented. The probe comprises first and second magnetic field sources, and a receiver of NMR signals. The first magnetic field source creates a primary, substantially non-homogeneous, static magnetic field in a region of interest in a medium outside the probe. The second magnetic field source creates an external time-varying magnetic field, which when being applied to the region of the static magnetic field, is capable of exciting nuclei in an extended sub-region of this region and generating the NMR signals.
