Juvenile Idiopathic Arthritis (JIA) is the most common musculoskeletal disorder in children. The temporomandibular joints (TMJs) are involved in majority of cases, and detection of early arthritic changes in these joints relies on contrast enhanced magnetic resonance imaging (MRI). However, with the paucity of evidence and consensus on the normal and pathologic changes in this small but complex joint, interpretation of TMJ MRIs remains to be difficult. This exhibit presents the normal growth related and arthritis related variations in the disease progression in TMJ MRIs of JIA patients. Read More

Accurate and reproducible sacroiliac joint (SIJ) assessment on MRI in pediatric patients is challenging, often with high inter-observer variation. To facilitate consistent SIJ assessment, numerous scoring systems have been proposed. We sought to systematically review articles that evaluated diagnostic accuracy and reliability of existing MRI-based SIJ scoring systems for the evaluation of spondyloarthropathy in children and adults, and assess their applicability to pediatric patients.

Increased fracture risk is a complication that occurs in the context of primary bone diseases such as osteogenesis imperfecta (OI). Despite being considered as the reference-standard, the use of dual-energy X-ray absorptiometry (DXA) to evaluate fragility fractures in OI has not been validated by prior systemic review. Identifying patients at greatest risk for bone fragility fractures and determining skeletal health markers that can monitor bone mass concerning response to bone-active treatments are important issues for clinicians. In this systematic review we assessed the clinical utility of DXA for evaluating osteoporotic bone in OI pediatric patients according to the U.S. Preventive Services Task Force guidelines. Read More

1. To review the contemporary literature and present an updated list of musculoskeletal and non-musculoskeletal imaging findings of patients with autoinflammatory diseases in our hospital. Most of these patients are found to have a genetic mutation that is responsible for their disease. 2. To present follow-up imaging findings, when available, and correlate those with patients’ symptoms and type of treatment administered in approximately 40 patients with autoinflammatory diseases such as Cryopyrin-associated autoinflammatory syndrome, familial Mediterranean fever, PAPA (pyogenic arthritis, pyoderma gangrenousum, and acne) syndrome and much more. These findings can be related to disease progression, treatment response or treatment-induced changes. Read More

X-Ray based manual Cobb angle measurement is inherently time-consuming and associated with high inter- and intra-observer variability. The existing automated scoliosis measurement methods suffer from insufficient accuracy. We propose a two-step segmentation-based deep architecture to automate Cobb angle measurement for scoliosis assessment. Read More

Scoliosis is a deformity of the spine that affects 2-3% of the population. Currently, the reference standard for assessing scoliosis is the manual assignment of Cobb angles at the site of the curvature center using X-ray images. This process is time consuming and unreliable as it is affected by inter- and intra-observer variability. To overcome these inaccuracies, machine learning (ML) methods can be used to automate the Cobb angle measurement process. Read More

Acoustic radiation force imaging (ARFI) is a type of quantitative sonoelastography (SE) that has been used to determine tissue stiffness in many disorders including liver fibrosis, breast cancer, thyroid nodules and more recently, cutaneous scleroderma. However the use of this technology for the assessment of skin lesions in the paediatric population has not yet been investigated. The purpose of this study is to test the feasibility of using ARFI SE to quantify the stiffness of morphea or localized scleroderma (LS) and hypertrophic burn scars (HTS), two skin conditions in which there is excessive deposition of collagenous and non-collagenous extracellular matrix causing fibrosis.

Whole-body (WB) magnetic resonance (MR) imaging in children is of special interest because it is radiation free and can be used to evaluate systemic conditions, exploiting the advantage of the superior soft-tissue contrast provided by MR imaging. An important clinical application of whole-body MR imaging in children is its use for screening of oncologic conditions, tumor characterization, and staging. However, the list of non-oncologic applications of WB MRI has recently expanded to include the evaluation of numerous multisystemic conditions. This is a pictorial review of different oncologic applications of WB MRI including cancer predisposition syndromes, solid neoplasias and lymphomas, as well as of non-oncologic applications of WB MRI including chronic recurrent osteomyelitis (CRMO), enthesitis related arthritis (ERA), vascular malformations and benign tumors. In this review we discuss the advantages and challenges of conventional and functional MRI sequences including the use of diffusion weighted imaging (DWI), color-encoded DWI enhanced with iron supplement Ferumoxytol as blood pool contrast agent, as well as the advantages and disadvantages of the recently introduced WB positron emission tomography (PET)/MRI.

Despite being recognized as a secondary sign of appendicitis, no clear definition exists about the amount of intra-abdominal fluid considered physiologic in children. The purpose is (1) to assess the amount of intra-abdominal free fluid by US and MRI in children with suspected appendicitis, (2) to detect the performance characteristics of US for detecting free fluid, and (3) to determine the association between fluid volume and perforated appendicitis. An additional ex-vivo study was done to assess the validity of US measurement abdominal free fluid volume using phantoms. Read More

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.
