Fig. 1. Example of fused volume showing slices in all three orthogonal
planes. Slices on left are original floating volume. Slices in middle show
transformed floating volume superimposed on and blended with original CT
volume (note match of bone structures, especially on sagittal view in bottom
row). Slices on right show original CT volume.

Fig. 2. Fused image showing false-positive Prosta-Scint (Cytogen) study.
Uptake originally thought to represent lymph nodes was found after fusion to
be vessel (1, arrow) and bowel (2, arrow) uptake on fusion.
Upper panel shows original Prosta-Scint transverse slice, and lower panel
shows Prosta-Scint transverse slice fused and superimposed on matching MRI
slice.

Fig. 3. Fused image showing true-positive Prosta-Scint (Cytogen) uptake.
Uptake was found after fusion to represent disease in lymph node
(arrows). Upper panel shows original Prosta-Scint transverse slice,
and lower panel shows Prosta-Scint transverse slice fused and superimposed on
matching MRI slice.
