Added value of 3D fast-field-echo (FRACTURE) sequences for cervical spondylosis diagnosis: a prospective multi-reader non-inferiority study.
Article in Insights into imaging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo assess the potential of fast field echo resembling a CT using restricted echo-spacing (FRACTURE) sequence to enhance conventional MRI in detecting bone abnormalities of cervical spondylosis. MATERIALS AND
methods137 consecutive patients with cervical spondylosis who underwent clinically indicated paired CT and MRI within 2 weeks between January and June 2024. After routine MRI, the 3D-FRACTURE sequences were performed. Three radiologists independently evaluated the data during three sessions: (1) CT with consensus, (2) routine MRI, and (3) FRACTURE, with a 4-week interval between sessions. Assessments included osteophytes, bony foraminal stenosis, posterior longitudinal ligament ossification (OPLL), their anatomical location, and diagnostic confidence, using CT as the reference standard. Inter- and intra-reader reproducibility was assessed using multi-rater Fleiss κ and the intraclass correlation coefficient (ICC), respectively. The non-inferiority assessment compared routine MRI/FRACTURE and CT diagnoses using a relative reduction margin of 0.5.
resultsThe study sample comprised 82 males and 55 females (age 56.9 ± 9.8 years). ICC indicated good to excellent inter-rater reliability for FRACTURE (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 (most ICC values < 0.7). The diagnostic confidence by FRACTURE sequences was significantly higher than by routine MRI (p < 0.001). Non-inferiority analysis demonstrated that FRACTURE and CT detection were similar for osteophyte, bony foraminal stenosis, and OPLL within a margin of 0.5.
conclusionThe FRACTURE sequence demonstrated comparable performance to CT in bone abnormalities detection in cervical spondylosis, superior to the routine MRI protocol. CRITICAL RELEVANCE STATEMENT: The FRACTURE sequence addresses the limitations of conventional MRI in evaluating bone abnormalities, potentially minimizing radiation exposure and streamlining the diagnostic process for patients. KEY POINTS: MRI has advantages in the evaluation of cervical spondylosis, but is still insufficient in bone abnormalities evaluation. The FRACTURE sequence performed comparably to CT in bone abnormalities detection in cervical spondylosis. MRI with FRACTURE sequences may provide a non-ionizing method for assessing cervical spondylosis in some clinical settings.
