Diagnostic value of dual-energy CT virtual monochromatic imaging for supraspinatus tendon injuries: a comparison with standard CT and MRI.
Article in European radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
objectivesThis study aimed to compare the diagnostic value of dual-energy computed tomography (DECT) virtual monochromatic imaging with that of standard computed tomography (SCT) in evaluating supraspinatus tendon injuries. MATERIALS AND
methodsThis retrospective study involved patients who underwent a single-source DECT system, 3.0-T MRI, and shoulder arthroscopy within 14 days. Three radiologists independently and randomly evaluated SCT, mono+ 50 keV, mono+ 90 keV, and MRI images to detect supraspinatus tendon tears and recorded their diagnostic confidence. Regions of interest were delineated to measure the CT attenuation values of torn, degenerated, and normal tendon regions in SCT, mono+ 50 keV, and mono+ 90 keV images.
resultsA total of 100 patients with supraspinatus tendon injuries were included. Significant differences in detecting supraspinatus tendon injuries were observed between SCT and DECT (p < 0.05) and between SCT and MRI (p < 0.05), without showing differences in detecting supraspinatus tears between DECT and MRI. CT attenuation values of tears in SCT, mono+ 50 keV, and mono+ 90 keV images were significantly lower than those of degenerative and normal regions (p < 0.001). Optimal CT attenuation values to differentiate between tears and degeneration on SCT, mono+ 50 Kev, and mono+ 90 Kev were 17.4, 28.0, and 14.2 with area under the curve (AUC) of 0.920, 0.978, and 0.938, respectively. Additionally, these values between degeneration and normal regions were 23.8 HU, 36.1 HU, and 19.6 HU with AUCs of 0.967, 0.970, and 0.946, respectively.
conclusionDECT demonstrated high diagnostic accuracy and reliability for qualitative and quantitative assessment of supraspinatus tendon injuries. KEY POINTS: Question Is DECT virtual monochromatic imaging capable of diagnosing supraspinatus tendon injuries when MRI is unavailable or contraindicated? Findings DECT demonstrated high diagnostic accuracy and reliability for qualitative and quantitative assessment of supraspinatus tendon injuries. Clinical relevance DECT can effectively and reliably diagnose supraspinatus tendon tears using both qualitative and quantitative methods and holds promise as a supplementary tool for MRI.
