Universal computed tomography angiography screening for blunt cerebrovascular injury: a systematic review of improved detection, clinical outcomes, and cost-effectiveness.
Review in Emergency radiology, 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
backgroundBlunt cerebrovascular injury (BCVI) is a serious complication of trauma that can lead to stroke if not detected early. Current selective screening criteria may miss a significant number of cases, prompting interest in universal computed tomography angiography (CTA) screening. We aim to evaluate whether universal CTA screening improves detection of BCVI compared with selective risk-factor-based screening in adult trauma patients, and to assess its impact on injury grade detection, clinical outcomes (stroke, mortality), cost-effectiveness, and imaging-related risks.
methodsA systematic review was conducted using PubMed, Embase, Cochrane, ProQuest, and Google Scholar through March 2026. Studies comparing universal versus selective CTA screening for BCVI in adult trauma patients were included. Data on detection, outcomes, and cost-effectiveness were extracted.
resultsA total of 1,362 records were identified, with 8 studies included after screening. Selective screening criteria missed 16%-37% of BCVI cases compared with universal CTA. Universal screening improved detection of both low- and high-grade injuries. Stroke incidence ranged from 8%-10%, with some cases occurring in patients without traditional risk factors. Imaging-related complications were low (AKI ~1.4%). Cost-effectiveness analyses showed universal CTA remained below willingness-to-pay thresholds (~$71,949/QALY) and improved quality-adjusted life years.
conclusionUniversal CTA screening for BCVI can be suggested as a diagnostic modality as it appears to improve detection of both low and high-grade injuries that may be missed with selective approaches. Additionally, CTA-based screening was deemed to be cost effective. Although limited, current evidence suggests that imaging-related harms are low, supporting the consideration of broader CTA screening strategies in appropriately selected trauma populations.
