Background MRI with xenon‐129 gas (Xe MRI) can assess airflow obstruction and heterogeneity in lung diseases. Specifically, Xe may represent a sensitive modality for future therapeutic trials of cystic fibrosis (CF) therapies. The reproducibility has not yet been assessed the context multi‐site study. Purpose To determine same‐day repeatability 28‐day children CF. Study Type Four‐center prospective, longitudinal. Population Thirty‐eight (18 females, 47%), median interquartile range (IQR) age 12 (9–14) years old, mild CF (forced expiratory volume 1 second (FEV ) ≥85% predicted). Field Strength/Sequence 3‐T, two‐dimensional (2D) gradient‐echo (GRE) sequence. Assessment MRI, FEV , nitrogen multiple‐breath wash‐out lung‐clearance index (LCI 2.5 were performed. reproducibility, was performed twice within first visit, procedures repeated at 28 days. hypoventilation quantified using ventilation‐defect percentage (VDP) reader‐defect (RDV). For VDP, hypoventilated voxels from segmented images identified threshold <60% mean whole‐lung signal expressed as volume. RDV, by two trained readers percentage. Statistical Tests Inter‐site comparisons conducted Kruskal–Wallis nonparametric tests Dunn's multiple‐comparisons tests. Differences individuals Wilcoxon matched‐pairs Bland–Altman used to evaluate repeatability, inter‐reader agreement. A P ‐value ≤0.05 considered significant. Results Median %‐predicted 96.8% (86%–106%), LCI 6.6 (6.3–7.4). had high (mean VDP difference 0.12%, 95% limits agreement [−3.2, 3.4]; RDV 0.42% [−2.5, 3.3]). At days, 26/31 participants (84%) fell Data Conclusion offer excellent short‐term reproducibility. Evidence Level 2 Technical Efficacy Stage

Cystic fibrosis (CF) is a genetically inherited disorder characterized by wide range of clinical manifestations and genetic variations. This study focuses on the molecular epidemiology CF in Russian population, utilizing data from national registry. The birth prevalence Russia has been analyzed over span years, revealing variations frequency. delves into landscape CFTR gene variants patients, showcasing diverse spectrum with predominance severe variants, some which are rare distinct global populations. A total 233 have documented, exhibiting frequencies ranging 0.01% to 51.5%, 47 these remaining uncharted within international databases. As 2021, modulator therapy introduced for patients under 19 heightening importance diagnosis. In 2023, more than 1,850 received therapy. Notably, impact complex alleles disease progression response targeted therapies gaining recognition. Comparisons European registries highlight distinctive features such as differences age distribution among patients. Additionally, emphasizes need ascertain significance pathogenicity newly identified along exploring their suitability therapies. integration insights management offers potential enhanced personalized therapeutic interventions. conclusion, this thorough analysis provides comprehensive understanding nuances population. By illuminating intricate relationship between manifestation, underscores essential role genetics shaping strategies improving patient outcomes. Further research ongoing exploration crucial optimizing care individuals era evolving options.
