Application value of gastric contrast ultrasonography in gastric tumors.
Review in Insights into imaging, 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
In recent years, gastric oral contrast ultrasonography (OCUS) and double contrast-enhanced ultrasonography (DCEUS) have emerged as promising imaging techniques for evaluating gastric tumors, particularly gastric cancer (GC), by providing beneficial insights into tumor morphology, vascular characteristics and response to therapy. OCUS is capable of identifying the thickened gastric wall and lesions by utilizing oral contrast agents. DCEUS, based on OCUS, further employs intravenous contrast-enhanced ultrasound to examine regions of interest, thereby revealing both the anatomical features and perfusion characteristics of the lesions. These two methods are known for being non-irradiating, cost-effective, noninvasive and real-time. With advances in contrast agents and imaging technology, OCUS and DCEUS are expected to become increasingly reliable and contribute to improving patient prognoses. However, the clinical application of these techniques is still evolving, limited by a lack of technical standardization, operator dependence, and inadequate evaluation in certain tumor subtypes and patient populations. This review summarizes the current state in clinical practice of OCUS and DCEUS in the screening, diagnosis, staging and treatment assessment of gastric tumors. It also proposes possible orientations for clinicians to address the identified limitations and improve the clinical value of OCUS and DCEUS, including the integration of artificial intelligence and molecular imaging, alongside establishing international standardization protocols, enhancing physician training systems, and expanding accessibility to primary care settings. Through these efforts, OCUS and DCEUS may become indispensable components of future GC management strategies. CRITICAL RELEVANCE STATEMENT: By summarizing gastric contrast ultrasonography across screening, diagnosis, T staging, N staging and treatment assessment in gastric tumors, and comparing with CT, EUS and endoscopy, this review proposes protocol standardization, operator training and AI-enabled quantification to advance its clinical application. KEY POINTS: Gastric tumors urgently require a simple, inexpensive, noninvasive and easily accessible screening method. Gastric contrast ultrasonography demonstrates utility in detecting and staging gastric tumors. Gastric contrast ultrasonography offers accessible and effective tools for screening of gastric cancer. Accelerating clinical application of gastric contrast ultrasonography demands standardization and technological innovation.
