Improving early gastric cancer detection in upper gastrointestinal series adding digital tomosynthesis (DTS): a preliminary study.
Article in Japanese journal of radiology, 2025. 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
The aim of this study is to evaluate the effectiveness of digital tomosynthesis (DTS) for improving the detection rate of early gastric cancer (EGC) in upper gastrointestinal (UGI) radiography. We retrospectively analyzed 57 patients with 62 pathologically confirmed EGC lesions. Imaging accuracy was compared between conventional double-contrast UGI and UGI with DTS, using endoscopy as the gold standard.In experienced readers, the detection rate improved from 71.0% with conventional radiography to 83.9% with DTS. For less experienced readers, the detection rate significantly increased from 53.4% to 79.0%. For lesions < 2 cm, DTS significantly improved detection only for less experienced readers (p < 0.05). For 2-3 cm lesions, both readers showed significant improvement (p < 0.05 and p < 0.01, respectively). No significant difference was found for lesions ≥ 3 cm. DTS also significantly improved detection for non-ulcerated lesions, particularly those with elevated structures, in the less experienced reader (p < 0.05).AUC analysis showed a slight improvement for experienced readers (0.86 → 0.98, p = 0.0604), while less experienced readers demonstrated significant improvement (0.76 → 0.96, p < 0.01). Inter-reader agreement for conventional radiography was 0.71, which improved to 0.90 with DTS. The total combined radiation dose for UGI and DTS was 4.7-5.3 ± 0.5 mSv, within acceptable limits.UGI with DTS significantly enhances EGC detection, particularly for lesions 2-3 cm and non-ulcerated elevated lesions, improving diagnostic accuracy and consistency, especially for less experienced radiologists. Given its minimal additional examination time (143 s) and cost-effectiveness compared to EGD, DTS may serve as a practical supplementary tool for gastric cancer screening and preoperative evaluation.
