The RV volumes and EF measured using the automated 3DE method correlated well with those from cardiac MR, especially in children with RVEF ≥ 45%, normal RV size, and good 3DE image quality. Therefore, the novel automated 3DE method may achieve rapid and accurate assessment of RV function in children with normal heart anatomy.</p>","PeriodicalId":19755,"journal":{"name":"Pediatric Radiology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144659782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computed tomography (CT) remains the gold standard imaging modality for assessing stable patients with potential abdominal injuries. This review outlines CT protocols specifically adapted for the pediatric population in the context of blunt abdominal trauma, with a focus on strategies to mitigate radiation exposure. It also highlights the 2018 update of the American Association for the Surgery of Trauma Organ Injury Scale-a detailed classification system ranging from grade I (minor) to grade V (severe)-and explores its relevance and impact on the management of pediatric patients compared to adults. A series of CT images illustrating the different grades of abdominal injuries along with a structured interpretation algorithm are provided to act as a pocket guide for radiology residents in emergency settings.</p>","PeriodicalId":19755,"journal":{"name":"Pediatric Radiology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144659779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
