The value of dual-energy CTA for control of surgically clipped aneurysms.
Article in European radiology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectiveComparison of image quality in DE-CTA with and without automatic head bone removal (BR) versus CTA with 16-detectors as a tool in postoperative evaluation of patients after neurosurgical clipping.
methodsIn this study 30 aneurysms that had undergone neurosurgical clipping were included: 18 with DE-CTA and 12 with conventional CTA. The images were further processed using the volume rendering technique (VRT) and BR. Two experienced neuroradiologists reviewed the images regarding the severity of artefacts surrounding the clip, visibility of the vessels and remnant necks. The results were compared with DSA images, if performed.
resultsSignificantly fewer disturbances by artefacts were observed in DE-CTA versus CTA in a 16-row system. Visibility of the surrounding vessels was satisfying in both techniques and there were comparable results with DSA with only one exception. All images produced with 140 kV provided fewer artefacts than those with 80 kV.
conclusionDE-CTA provides better image quality with fewer disturbances by clip artefact, a satisfying evaluation of remnant aneurysm necks and the surrounding vessels. As this method is easily performed and readily accessible with fast image post-processing using BR it provides an opportunity to avoid invasive DSA in the evaluation of suspected aneurysm rests.
