Comparative effectiveness of FAST combined with MRI and CT in wound evaluation of blunt abdominal trauma.

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
Background: Blunt abdominal trauma, often resulting from motor vehicle collisions (MVCs), assaults, recreational accidents, or falls, is commonly assessed in emergency departments using the focused assessment with sonography for trauma (FAST). FAST offers advantages such as ease of use and rapid identification for intra-abdominal free fluid, an indirect marker of visceral injury. However, its diagnostic performance is highly dependent on operator expertise, limiting its ability to accurately characterize the type and severity of injuries. Objective: This study aimed to assess the diagnostic performance of FAST combined with magnetic resonance imaging (MRI) compared to computed tomography (CT) in the evaluation of hemodynamically stable patients with blunt abdominal trauma. Methods: A retrospective, single-center study was conducted involving 87 patients admitted between February 2018 and September 2023 with suspected blunt abdominal trauma. Only hemodynamically stable patients were included in this study. All patients were underwent FAST, MRI, and CT imaging, with surgical or pathological findings serving as the gold standard. The diagnostic accuracy, localization capability, and time to diagnosis were between the FAST + MRI and CT. Results: Among the 87 patients, 36 were confirmed to have abdominal organ injuries. The FAST + MRI approach identified 34 true-positive cases, whereas CT identified 30. FAST + MRI showed significantly higher diagnostic accuracy and localization capability compared to CT ( Conclusion: Our findings indicate that in hemodynamically stable patients, the combination of FAST and MRI provides superior diagnostic accuracy and localization for blunt abdominal trauma compared to CT, with timely diagnostic efficiency. These findings suggest that FAST + MRI may serve as a useful complementary imaging strategy in hemodynamically stable patients; however, further prospective studies comparing this approach to contrast-enhanced CT and incorporating patient outcome measures are warranted.
