High resolution (0.55m isotropic) 3D radial center-out
ultra-short echo time (UTE) MRI with interspersed fat
saturation pulses is acquired for a case of a skull bone
tumor and compared to CT images. In the presented case
the tumor has not yet infiltrated into the soft tissue
and the thin separating layer of bone can clearly be
identified on both modalities. UTE images additionally
show the integrity of the meninges, which are a short T2
species not visible at regular echo times or in CT. This
suggests that UTE MRI might be a valuable additional
modality in bone tumor diagnosis.
