Learning objectives: 1.Review the main pediatric cardiomyopathy phenotypes. 2.Clarify the role of MRI across the care pathway. 3.Walk through the key MRI sequences we actually use in kids. 4.Recognize the essential imaging findings that help us differentiate among them. - Introduction: Pediatric cardiomyopathies are a rare heterogeneous group of myocardial diseases but are the first cause of heart transplantation in children. Causes are diverse—genetic mutations, coronary anomalies, infections, toxins, arrhythmias—and sorting out phenotypes can be tricky because adult criteria are often not applicable to kids and because many kids don’t tolerate long exams. - Imaging techniques: Echocardiography represents the first first-line modality but it is often complemented with CMR as it allows a radiation-free differentiation between different phenotypes with unique myocardial tissue characterization, playing a key role in diagnosis, risk stratification, and treatment assessment. - Key MRI sequences: Conventional cardiomyopathies protocols in children may use 1.5 or 3 Tesla field strengths and include the following sequences: Initial localizers. Cine imaging. Phase contrast. Parametric mapping. LGE. - Dilated Cardiomyopathy: Most common. Leading cause of heart transplant. Dilated chambers. Reduced systolic function. LGE: Patchy or longitudinal mid-wall, transmural, subepicardial, or diffuse subendocardial involvement. Presence of LGE indicates poor prognosis and increased risk of SCD. Native T1 mapping is suggested to be the strongest independent predictor of diffuse myocardial disease, allowing for the identification of patients at risk for adverse outcomes. - Hypertrophic Cardiomyopathy: 2nd most common. LV hypertrophy z-score >2.5 (no family history) or >2 (with family history/genetic test). LVOT obstruction and SAM. LGE: Independent risk factor for SCD. Differential diagnosis with athlete's heart. - Arrhythmogenic Cardiomyopathy: RV and/or LV dilatation and reduced EF. Wall motion abnormalities – most important finding in kids. Myocardial fibrosis. Fatty infiltration rare in children. - Restrictive Cardiomyopathy: Rarest CMP. Non-dilated biventricular failure and biatrial dilatation. Ddx: constrictive pericarditis. - Excessive trabeculation/NCCM: Non-compacted/Compacted myocardium ratio > 2.3 measured in diastole. In the absence of dilation or systolic dysfunction, can be considered a phenotypic trait not necessarily associated with CMP. Read More

Thyroid cancer is the most prevalent endocrine malignancy in the pediatric population. Accurate diagnosis and staging of thyroid carcinoma demand a multimodality approach, including anatomic imaging with US, CT, and MRI, alongside functional or metabolic nuclear imaging. Novel imaging techniques such as US elastography, contrast-enhanced US (CEUS), superb microvascular imaging (SMI) and dual-source dual-energy thyroid CT have offered non-invasive tools to assess disease status. Furthermore, the emerging field of radiomics/radiogenomics and artificial intelligence is continuously growing, creating models to classify or predict disease behaviour. We provide a comprehensive overview of the essential imaging characteristics of pediatric thyroid carcinoma using conventional and novel imaging techniques. In addition, we illustrate the multimodality, multidisciplinary, and collaborative approach across pediatric radiology and nuclear medicine in pre-operative, post-operative and post-treatment imaging surveillance of cancer thyroid in children.

Whole body (WB) MRI is a valuable method for surveying the overall burden of systemic diseases such as juvenile idiopathic arthritis (JIA), directing further diagnostic and treatment approaches. Consensus-driven development and validation of a standardized WB-MRI scoring system for JIA has important clinical utility in timely detection and monitoring of disease activity, and serves as an outcome measure in research. We describe our experience utilizing a formal consensus approach amongst imaging and/or clinical JIA experts towards developing a novel WB MRI scoring system to assess disease activity in JIA.

Clinical assessment of the Sacroiliac Joint (SIJ) is limited due to the location and anatomy of the joint.<b> </b>Magnetic Resonance Imaging is a sensitive, non- invasive tool in detecting early SIJ inflammatory changes and structural damage in Juvenile Idiopathic Arthritis (JIA). The quantification of interval change of pediatric SIJs using MRI based scoring methods will serve as an important objective outcome measure for the assessment of disease severity and treatment effectiveness in JIA.
