This
study provided a quantitative evaluation of skull images obtained using UTE
MRI and a direct comparison to those from CT.
The skull thickness measured from UTE images showed good agreement
with those obtained from CT images in different slices. There is also a good
correlation between the thickness measurements obtained from CT and UTE
images. Signal intensity based evaluation showed that there is no statistical
difference between UTE and CT images in outer, inner layer and diploe of the
skull. The comparison of bone UTE MRI and CT of skull suggests that UTE
images match closely with CT images.
