En zonas rurales donde hay pocos médicos, esa diferencia puede hacer que un enfermo quede sin atender o que uno sano sea tratado de más.

Yet, the extent of agreement between sonographers, limitations of existing World Health Organization (WHO) protocols, and the applicability of ultrasound video remain poorly understood. Methods: In 2024, six sonographers performed ultrasound scans for 3302 participants aged 5-92 years within SchistoTrack, a community-based cohort in rural Uganda. We adapted and standardised the WHO Niamey protocol for the collection of curated ultrasound images of liver fibrosis patterns related to Schistosoma mansoni (ranging A-F) and liver ultrasound video sweeps. PPF was defined as patterns C-","pubDate":"2026-11-02","url":"https://www.medrxiv.org/content/10.64898/2026.11.02.26367045v1?rss=1"},"indexado":"2026-11-03T09:02:53.279Z"}}
