Since conventional MRI cannot easily distinguish
cortical bone from neighboring tissues such as tendons,
ligaments and articular capsule, we evaluated the use of
UTE imaging for improved visualization and segmentation
of vertebrae. The study was conducted on a 3T system on
two normal subjects using a work-in-progress 3D UTE
sequence from Siemens. CISS images were also obtained
for comparison. The results showed that UTE better
distinguished cortical bone from other tissues, enabling
easier segmentation of the vertebrae. UTE imaging may be
useful for functional, developmental and diagnostic
assessment of spine, such as the studies of scoliotic
deformities or osteophyte formation.
