Automated Assessment of Cerebral Arterial Perforator Function on 7T MRI.
Article in Journal of magnetic resonance imaging : JMRI, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
backgroundBlood flow velocity and pulsatility of small cerebral perforating arteries can be measured using 7T quantitative 2D phase contrast (PC) MRI. However, ghosting artifacts arising from subject movement and pulsating large arteries cause false positives when applying a previously published perforator detection method. PURPOSE: To develop a robust, automated method to exclude perforators located in ghosting artifacts. STUDY TYPE: Retrospective. SUBJECTS: Fifteen patients with vascular cognitive impairment or carotid occlusive disease and 10 healthy controls. FIELD STRENGTH/SEQUENCE: 7T/cardiac-gated 2D PC MRI. ASSESSMENT: Perforators were automatically excluded from ghosting regions, which were defined as bands in the phase-encoding direction of large arteries. As reference, perforators were manually excluded by two raters (T.A., J.J.M.Z.), based on perforator location with respect to visible ghosting artifacts. The performance of both censoring methods was assessed for the number of (N STATISTICAL TESTS: For within-method comparisons, inter- and intrarater reliability were assessed for the manual method, and test-retest reliability was assessed for both methods from repeated 2D PC scans (without repositioning). Intraclass correlation coefficients (ICCs) and their 95% confidence intervals (CIs) were determined for N
resultsThe automated censoring method showed a moderate to good ICC (95% CI) vs. manual censoring for N DATA
conclusionThe proposed automated censoring method can reliably exclude small perforators affected by ghosting artifacts. LEVEL OF EVIDENCE: 3. TECHNICAL EFFICACY STAGE: 1.
