Motivation: MRI is still insufficient in the evaluation of bone abnormalities.
Goal(s): To assess the diagnostic performance of fast field echo resembling a CT using restricted echo-spacing (FRACTURE) in detecting cervical bone abnormalities.
Approach: 137 consecutive patients with cervical spondylosis were continuously enrolled. CT, routine MRI and 3D-FRACTURE sequences were performed. Three radiologists independently evaluated osteophytes, bony foraminal stenosis, posterior longitudinal ligament ossification (OPLL).
Results: Good to excellent inter-rater reliability for FRACTURE with CT (osteophytes: ICC, 0.83–1.00; OPLL: ICC, 0.73–0.92; bony foraminal stenosis: ICC, 0.76–0.98), which was superior to conventional MRI.FRACTURE passed the non-inferiority test within a margin of 0.5 with higher diagnostic confidence.
Impact: The FRACTURE protocol demonstrated comparable performance to CT in assessing bone abnormalities in cervical spondylosis, offering the potential to reduce radiation exposure and streamline the diagnostic process for patients.
