Nuclear Magnetic Resonance imaging apparatus of the type for imaging specific parts of the body, the device including a magnetic structure (1), having a cavity (101) for accommodating the limb part to be examined, which may be accessed from the outside, and in which, or at least in one part of which (V) the necessary magnetic fields are generated. The magnetic structure (1) is supported in such a manner as to be able to oscillate (O) about a horizontal axis, which is parallel to the static magnetic field, whereas the axis of oscillation (O) is staggered with respect to the central axis, which is parallel thereto and passes through the cavity volume (V), wherein the static magnetic field has the characteristics required for valid imaging, to such an extent that the relevant volume (V) moves from an uppermost position to a lowermost position, the two extreme positions as well as those intervening therebetween being adjusted to the head and/or neck and/or upper limbs level in the standing and/or sitting positions of the patient and to the lower limbs level in the standing and/or sitting positions of the patient respectively.
