Learning Objectives: -To recognize characteristic MRI features of chronic recurrent multifocal osteomyelitis (CRMO) that distinguish it from infectious osteomyelitis and malignancy -To understand common imaging mimics including focal periphyseal edema zones, developmental variants, and physiologic bone marrow changes -To appreciate the clinical-imaging discordance in CRMO and the role of whole-body MRI in detecting subclinical disease Background: CRMO is a rare autoinflammatory bone disorder in children that poses diagnostic challenges due to overlapping features with infection, malignancy, and benign conditions. Early recognition of characteristic imaging patterns is crucial to avoid unnecessary biopsies, inappropriate antibiotic therapy, and diagnostic delays that may lead to skeletal complications.

Learning Objectives: -To recognize age-specific radiographic manifestations of rickets and understand how imaging features evolve from infancy through adolescence. -To distinguish between nutritional, genetic, and systemic causes of rickets using characteristic imaging patterns. -To identify common mimics of rickets and differentiate them from true metabolic bone disease. -To understand the complementary roles of radiography and MRI in challenging cases. Background: Rickets is a pediatric metabolic bone disorder characterized by imaging features that change according to the patient's age and underlying cause. Some conditions may mimic rickets due to similar radiologic features; therefore, accurate recognition of hallmark radiographic signs—including metaphyseal fraying, cupping, widening, and angular deformities—is critical for timely diagnosis, appropriate management, and differentiation from mimics. Nutritional rickets remains the most prevalent cause, particularly among exclusively breastfed infants without adequate vitamin D supplementation. However, older children with rickets frequently have genetic and systemic causes, such as renal and phosphate metabolism disorders. Although radiographs remain the principal imaging modality for evaluation, MRI may provide enhanced diagnostic precision in challenging or unclear cases. Clinical red flags warranting imaging evaluation include persistent or worsening bowing beyond expected physiologic ages, motor delays, pathologic fractures, failure to thrive, and lack of response to vitamin D supplementation in older children, which suggests genetic or renal etiologies rather than simple nutritional deficiency. This educational poster presents an age-based approach to diagnosing rickets, illustrating classic radiographic features across different age groups and etiologies. Key imaging findings in nutritional rickets, hypophosphatemic rickets, and renal osteodystrophy are systematically compared. Common mimics—including scurvy, non-accidental trauma, Blount's disease, osteogenesis imperfecta, and physiologic variants—are reviewed with comparative imaging to enhance diagnostic accuracy. Emphasis is placed on pattern recognition, and the role of advanced imaging in equivocal cases. Read More

Fetal MRI is increasingly used in congenital diaphragmatic hernia (CDH) cases for enhanced anatomical imaging and prognostic assessment. Radiomics allows extraction of complex quantitative data that may enhance prediction capabilities beyond standard lung volume measurements. This investigation sought to determine which radiomic characteristics distinguish normal fetal lungs from those affected by CDH. Read More

Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that measures the diffusion of water molecules restricted by cellular structures, providing insights into tissue microarchitecture. In the physeal metaphyseal complex (PMC), columns of cartilage and newly formed bone restrict water diffusion primarily along the longitudinal axis. This study aims to delineate physeal DTI parameters—such as tract volumes—in young children. By establishing early developmental benchmarks, we address a gap in pediatric musculoskeletal DTI literature and assess the potential of DTI in monitoring growth patterns. Read More
