To date, a standard for CRD has not been established. Plain radiographs are a cost-effective, low-risk option for studying osseous structures in great detail. It is well known that bone age is superior to chronological age for determining biological and structural maturity; for decades, pediatricians have relied on plain films of the wrist and hand for assessing bone age in children (e.g. Greulich & Pyle Atlas, Tanner Whitehouse Method). However, some have proposed new approaches with greater accuracy and reliability across all ages and ethnic groups. Here, we present a new standardized radiographic dimension, CRD, as a tool to assess developmental maturity, which can be readily obtained from standard medical imaging platforms. Read More

Congenital anomalies of bone are many and can be difficult to approach. In addition, it is important to recognize that while some of these anomalies occur sporadically or in isolation, others are inherited or associated with systemic conditions/syndromes that require further assessment, diagnostic testing, and proper referral.
In this two-part exhibit, congenital bone anomalies of the upper and lower extremities will be reviewed. The first part of the exhibit will cover upper extremity anomalies while the second part will focus on the lower extremity. The purpose is multifold: 1. To illustrate the wide spectrum of congenital bone anomalies based on classic clinical presentation and demographics. 2. Highlight key imaging characteristics across multiple modalities to allow for accurate differentiation between the various congenital bone anomalies of the extremities. 3. Guide the viewer to proper workup and referral for these entities. Read More

There is limited understanding and utilization of dynamic contrast enhancement MRI of marrow, periosteum and cartilage for diagnosis of musculoskeletal (MSK) disease in children. This is partly due to limited availability of pediatric disease models of marrow inflammation, infection, infiltration, or involvement by tumor. Herein we explore signal intensity time curves of relevant MSK targets using a 3D Golden-angle RAdial Sparse Parallel (GRASP) MRI technique. GRASP is an accelerated, free-breathing dynamic acquisition that has been shown to reduce the need for sedation. We aim to establish a baseline for normal enhancement characteristics of marrow, cartilage, synovium and periosteum of the growing skeleton in a sheep model as a precursor to translation to children.

Magnetic resonance imaging (MRI) is a robust imaging modality. However, the necessity for patients to hold still commonly requires pediatric patients to be sedated (which carries its own risks), or limits the useful scan time window in some nonsedated pediatric patients. In some circumstances, there is no way to control the movement of the imaging target (i.e. fetal MRI).
MRI is also very customizable, and there are number of options currently available to accelerate MR imaging. It is important for pediatric radiologists supervising pediatric MRI examinations to have a broad understanding of the technology that is currently available, in order to optimize imaging quality and mitigate sedation use.
In this educational exhibit, we will briefly review a number of acceleration techniques available on the Siemens platform, noting that other vendors have very similar options available for their customers. These techniques will include single-shot fast spin echo , balanced steady-state gradient echo, parallel imaging, radial imaging, and simultaneous multislice imaging. Our review will focus on the relative advantages and disadvantages of these techniques, rather than on the physics of image generation. Read More

Brain MRI in children is often limited by motion artifacts. Radial k-space sampling techniques have been shown to reduce motion artifacts.
