MRI is moving toward volumetric imaging, because of the flexibility it allows for reformatting a single image volume in any oblique plane and the simplified workflow. Reduced field-of-view (rFOV) capability can enable focused 3D high resolution imaging, even of deep-seated regions, within a short scan time. This work presents an rFOV 3D FSE sequence using outer volume suppression and demonstrates its utility in a challenging application area-MRI of the orbits-in comparison with an existing 2D FSE protocol.
