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

High-resolution ultrasonography (US) is a valuable and accessible imaging tool to assess and characterize the thyroid gland in children. Pediatric thyroid nodules are infrequent. However, the incidence of thyroid carcinoma in children is near twice the adult population, where the risk of malignancy is up to 15%. Children also have an increased risk for recurrence (39%) as compared to adults, justifying further work and a more aggressive approach. Prompt recognition of the common and uncommon sonographic features of thyroid cancer in children will allow radiologist to identify this malignancy in early stages of the disease, expediting appropriate treatment improving the standard of patient care. The purpose of this exhibit is to 1. To illustrate the spectrum of sonographic findings of thyroid cancer in a pediatric population. 2. To describe the typical sonographic characteristics of malignant thyroid nodules in children. 3. To identify the uncommon features of pediatric thyroid cancer. 4. To describe an appropriate approach to deal with uncertain diagnosis. Read More

1. To determine short-term interval changes in T2 maps of knee cartilage of healthy boys before and after a 2-minute knee-squat exercise at 1.5T and 3T MRI; 2. To determine interval changes in T2 maps pre-exercise at 1.5T vs. 3T, and post-exercise at 1.5T vs. 3T; 3. To determine interval changes pre- and post-exercise among minimal-, moderate-, and high-activity subjects at 1.5T and 3T; and 4. To determine inter- and intra-reader reliability of 1.5 and 3T values. Read More
