Preoperative evaluation of internal carotid artery invasion in glomus jugulare tumors: applicability of contrast-enhanced 3D brain volume imaging.
Article in Neuroradiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeAccurate preoperative assessment of internal carotid artery (ICA) invasion is crucial in managing glomus jugulare tumors. This study evaluated the efficacy of contrast-enhanced 3D BRAin VOlume (BRAVO) imaging compared to enhanced fast spin-echo (FSE) T1-weighted imaging and enhanced computed tomography (CT).
methodsRetrospective analysis was performed on imaging data from surgically confirmed glomus jugulare tumors, including temporal bone enhanced BRAVO, enhanced T1-weighted FSE, and temporal bone enhanced CT sequences. ICA encasement and stenosis by tumor were graded and compared based on intraoperative assessment. According to Fisch criteria, the preoperative image C-type based on BRAVO, FSE and CT were separately and compared with surgical C-type (gold standard).
resultsAmong 21 patients, For image Fisch C-type, BRAVO showed excellent agreement with surgical C-type (κ = 1.000, P < 0.001), outperforming enhanced FSE (κ = 0.561) and CT (κ = 0.702). For ICA encasement, BRAVO had moderate agreement (κ = 0.513), slightly better than enhanced FSE (κ = 0.431) but inferior to enhanced CT (κ = 0.648). For ICA stenosis, BRAVO (κ = 0.588) surpassed enhanced FSE (κ = 0.339) but was less accurate than enhanced CT (κ = 0.716).
conclusionEnhanced BRAVO and temporal bone enhanced CT are complementary for assessing ICA involvement in glomus jugulare tumors, offering superior accuracy over conventional FSE imaging.
