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.
