For each exam, fluoroscopy time, dose-area-product (DAP), reference air kerma (RAK), and patient demographic information were analyzed. RAK, DAP, and fluoroscopy time were tested using Pearson's correlation methods for the three most frequently performed procedures. The influence of patient habitus on dose was studied using linear regression methods. Dose performance among radiologists was compared and so the Wilcoxon signed-rank test between radiologists with ≤ 5 years and > 5 years of experience post fellowship.

RAK demonstrated a stronger correlation with DAP (upper gastrointestinal (UGI), R=0.97; P<0.0001) than with fluoroscopy time (UGI, R=0.19; P<0.0001). RAK values were linearly correlated with patient weight (UGI, R=0.49; P<0.0001). A stable trend of median RAK values was observed across the studied time periods. Radiologists with ≤ 5 years' experience showed significantly lower (P<0.0001) RAK than those with > 5 years' experience.</p><p><strong>Conclusion: </strong>Variations of pediatric general fluoroscopy dose performance were observed when comparing with other investigations.

VPD is common in patients with cleft palate and presents significant challenges, often necessitating advanced imaging techniques for surgical treatment planning. Recent advancements in magnetic resonance imaging (MRI) have enhanced the capability to obtain detailed static images of velopharyngeal structures at rest and during sustained phonation, which are comparable or superior to traditional technologies. MRI is particularly effective at assessing the levator veli palatini muscle, a critical component of the velopharyngeal mechanism. As a non-invasive, radiation-free imaging method with high-resolution capabilities, MRI is becoming increasingly popular for VPD evaluation, especially in the pediatric population. However, understanding the complexities of VPD requires specialized knowledge spanning craniofacial surgery and speech-language pathology, which is often inaccessible in the radiology literature. While technical guides on MRI protocols for VPD exist, foundational knowledge of the velopharyngeal mechanism and its relevance to cleft anatomy remains underrepresented. This primer aims to bridge the gap between radiology and the complex multidisciplinary care of VPD by equipping radiologists with the knowledge necessary to effectively interpret MRI findings and integrate them into diagnostic and therapeutic pathways. By reviewing velopharyngeal and cleft anatomy, relevant VPD terminology, the principles of surgical management, and the role of MRI in velopharyngeal assessment, this paper provides radiologists with the context and tools to collaborate and communicate more effectively with cleft and craniofacial teams that treat this condition.</p>","PeriodicalId":19755,"journal":{"name":"Pediatric Radiology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143425929","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}

Our aim is to examine the key features of MRI safety and how safety culture impacts important aspects of MRI processes, including patient and staff screening, physical barriers, zoning regulations, emergency response protocols, and adverse event management. This article also explores the cornerstone of MRI safety, the Just Culture approach, which emphasizes transparency, accountability, and improvement of processes over punishment. Key efforts towards building and maintaining safety culture focus on raising awareness, outlining escalation procedures, and instilling a safety-first mindset.
