They can superimpose MR and CT datasets and can accurately guide percutaneous procedures providing live instrument visualization and the capability of re-imaging without patient transfer. These techniques, however, have been minimally used for accessing the head.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>Using an Allura Xper FD20 unit (Philips Healthcare Andover, Massachusetts, USA), three-dimensional image overlay and FD-CT navigation were used for percutaneous n-butyl cyanoacrylate (nBCA) embolization of an intraorbital mass in a 69-year-old man.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three-dimensional image overlay provides accurate anatomical relationships between the optic nerve and vascular portions of the mass.
