The Choosing Wisely initiative, led by the American Board of Internal Medicine (ABIM) Foundation in collaboration with over 80 medical societies and organizations, was launched in 2012 in the United States and Canada. Choosing Wisely is a response to the estimation that roughly 20% of current medical tests and therapies lack justification, provide no value, and may pose risks. The American Academy of Pediatrics (AAP) became a participant in Choosing Wisely from the start, resulting in 16 pediatric specialty-specific lists designed to assist AAP members in responsible healthcare resource management. While pediatric radiology did not develop its own list, imaging recommendations were included on fully half of the published AAP/Choosing Wisely lists. Read More

Acquiring high-resolution diagnostic pediatric MR images is challenging due to patient movement during long scan times, resulting in spatial blurring and motion artifacts. Developing rapid acquisition methods is essential to obtaining diagnostic-quality MR images. Recently, an echo planar imaging (EPI)-based Multi-Inversion Spin and Gradient Echo (MI-SAGE) sequence was reported to acquire multiple tissue contrasts from adult brains with a single 1-minute scan. This study demonstrates the utility of a 1-minute MI-SAGE acquisition in pediatric subjects to generate clinically relevant synthetic image contrasts (T1w, T2w, T2*w) from quantitative relaxometry maps (T1, T2, and T2*).

Access to healthcare, and in particular to pediatric subspecialties, including pediatric radiology, is limited. Increasingly limited access creates or accentuates preexisting disparities and injustices. However, because of the complexity of the issue, it is difficult to objectively study and quantify it. This exhibit will describe current barriers to pediatric radiology access, available research tools and methodologies that can help us measure the impact of such barriers. Then, we propose a research agenda to systematically approach the problem. Read More

The number of reconstruction surgeries of the anterior cruciate ligament (ACL) in pediatric patients has risen dramatically over the past two decades as a result of changes in treatment philosophy and perhaps frequency of injury. It is therefore important for pediatric radiologists to recognize the normal postoperative appearance of the different surgeries as well as their complications. This educational exhibit will review the types of reconstructive methods used in both skeletally immature and mature patients (physeal-sparing, partial transphyseal and transphyseal), complications (growth disturbances, graft failure, impingement, arthrofibrosis, intra-articular bodies) and relevant imaging findings on plain radiography and MRI.

Pediatric pathology involving the jejunum is more common than one might initially expect. Early recognition of the important imaging characteristic, atypical findings, and useful imaging tools/techniques in the evaluation of jejunal pathology is important in prompt diagnosis and management of these patients.

In this educational exhibit we will present a series of cases involving pathology of the jejunum encountered in the pediatric population. We will focus on important pathologies affecting a difficult to image and sometimes forgotten portion of the intestine.

A range of acute, emergent and post-surgical cases are presented. Using an interactive, quiz based approach we will discuss the following pediatric pathologies that may affect the jejunum of pediatric patients from neonates to teenagers with multimodality imaging and pathologic examples:
Atresia
Meconium plug syndrome
Pneumatosis
Enteritis
Foreign body
Small bowel intussusception
Lymphoma
Ischemia/shock
Hernia

Juvenile Granulosa Cell Tumor of the Testis is a rare testicular tumor that falls within the category of stromal cord neoplasms. There have been less than 50 cases described in the literature with all cases being described as having a cystic component (1, 2). We present a case of a 6 month old boy presenting with unilateral scrotal swelling. Ultrasound evaluation revealed an entirely solid, hypervascular, intratesticular mass. Alpha-fetoprotein levels were negative. At surgery, radical orchiectomy was performed and pathology revealed a Juvenille Granulosa Cell Tumor.

Testicular tumors arising in the neonatal and prepubescent period are a unique set of tumors distinct from their adult counterparts. In this younger age group, germ cell tumors predominate. Of the germ cell tumors, Yolk Sac tumors are the main tumor of clinical significant, and the reason why alpha-fetoprotein is such a relevant marker (3). Stromal cell tumors account for only a small percentage of testicular tumors within this age group. When they do occur, Juvenile Granulosa Cell Tumors (JGC) predominate, particularly if the child is under 1 year of age, with this tumor type being the most common testicular tumor present at birth (3,4). JGC tumors are associated with genetic and structural anomalies of the Y chromosome, ambiguous genitalia, and contralateral undescended testis. One of their defining pathologic characteristics is positive staining with Inhibin (3).To date there are no cases of metastatic JGC tumors. In all reported cases, Sonographic evaluation demonstrates a grossly multicystic tumor (2). The adult variant of Granulosa Cell tumors can appear as a solid mass with little or no cystic component and carries the risk of metastasis of approximately 20% (2). Surgical management of testicular JGC tumors has largely been radical orchiectomy but, some studies have shown tumor sparing excision to be curative in cases with salvageable testicular parenchyma (2). This finding highlights the importance of including stromal cell tumors, particularly JGC, in the differential for solid appearing testicular masses in the neonate. With more reported cases of JGC tumors of the testes, surgical management could include a more conservative approach. Although JGC tumor of the testis is not known to be malignant, given the atypical features of this tumor and similarities with its more malignant adult counterpart, close surveillance is warranted to ensure benign course.

Accidents remain a top cause of morbidity and mortality in pediatric patient. Assessment for blunt trauma to the abdomen is difficult in the trauma patient and findings of bowel injury can be subtly or confounded by visceral injuries. The most specific finding of free air in blunt hollow visceral organ is often minimally present, or entirely unseen. The pediatric radiologist must be familiarity with the more often seen and less specific secondary signs on CT, including free fluid, bowel wall thickening, and mesenteric contusion injury. We present, by case example, bowel injuries in the traumatic pediatric patient and their management and outcomes, while addressing common pearls and pitfalls. As many of these patients do well with non-operative treatment the radiologist must also be familiar with findings that would allow such option, to appropriately advice referring providers and manage potential re-image of the pediatric patient.

We present novel brain MRI findings in 2 children presenting with seizures due to TMCO1 mutation. Both children had absent olfactory bulbs and olfactory tracts and hippocampal malrotation. EEG demonstrated right temporal slow waves and intermittent focal slowing. One child had pontine hypoplasia, hypoplasia of bilateral optic nerves/chiasm, and an absent right cochlear nerve. In both children, there was increased mineralization in bilateral globi pallidi and bilateral substantia nigra on SWI sequence, possibly from excessive calcium. Ventriculomegaly and cavum septum pellucidum were also present in both children. Spine MRI revealed segmentation abnormalities including partial fusion of T2/T3 vertebral bodies and fusion of the posterior elements of T3-T5. Both children exhibited dysplastic and bifid ribs, demonstrating partial posterior fusion. Right renal agenesis was also noted in one child.

TMCO1 mutation results in cerebro-facio-thoracic dysplasia (CFTD) due to abnormal calcium homeostasis. The transmembrane and coiled-coil domains 1 protein directs formation of endoplasmic reticulum calcium leak channels which facilitate calcium leak upon overload of the endoplasmic reticulum. Failure of calcium leak results in abnormal cell function resulting in delayed osteogenesis, reduced mitochondrial volume, reduced mitochondrial respiration, and decreased endoplasmic reticulum stress mediated apoptosis. These children have distinctive craniofacial dysmorphism, global developmental delay, and skeletal anomalies. Previous studies have demonstrated only mild ventriculomegaly, corpus callosum abnormalities, frontotemporal atrophy, and three cases of associated epilepsy. Olfactory bulb agenesis may be due to abnormal development of the cribriform plate of the ethmoid and failure of olfactory nerves to induce development of the olfactory bulb from the telencephalon. We demonstrate that TMCO1 may play a more extensive and previously undescribed role in neurodevelopment, specifically in the formation of the hippocampus, optic nerve, and pons. Read More

To describe and discuss some of the challenges of performing DEXA scans on pediatric patients including positioning, technical obstacles, reference data and post-processing and describing how to overcome some of these challenges.
1. Positioning: Many patients with syndromes, have scoliosis, para or quadriplegia, or contractures that make placing the patient on the table difficult. In these patients, imaging has to be adapted to the patients’ abilities and some components may need to be eliminated. With cerebral palsy and muscular dystrophy for example, the whole body and AP spine might have to be deferred and only a hip and forearm obtained.
2. Technical obstacles: There are many technical obstacles that can present challenges when performing DEXA scans on pediatric patients. Patients who have prostheses or metal rods present technical obstacles. There is no way to remove the metal artifacts in a whole body scan on these patients, so a hip or forearm might be the most accurate way to obtain the patient’s bone density due to this technical factor.
3. Reference Data: The reference data for pediatrics is limited in national data bases. For example, a total Z-score will not be factored for children under the age of 5 because there is not enough information in the national database for comparison. There is also not enough information on children of certain ethnicities. This presents a problem when diagnosing and treating children with abnormal bone density.
4. Post-processing could be different for each user. It can also be different for machines manufactured by different companies. For example, a machine made by Hologic might produce different numbers than a machine made by General Electric. Also, if the user does not place the post-processing tools the exact same way the prior user did, the results can vary.
Overcoming some of these challenges has presented opportunities to grow. Sedation is used for children who may not be able to be perfectly still for a Dexa and positioning tools help on some of the more challenging patients. Learning how to work around prostheses and working with the ordering physicians and radiologists with the limited amount of reference data are a few ways of growing from these challenges. Placement of post-processing tools are the key to providing key information in comparing Dexa scans for patients who have them regularly for evaluations. Staff Education is the largest challenge to overcome. Read More

Computed tomography with its excellent spatial and temporal resolution remains valuable diagnostic modality in pediatrics. On the other hand there has been increasing attention placed on the radiation risks associated with CT imaging, especially in children.
In recent years many advances in CT hardware and software, for example automatic exposure control tools and iterative reconstruction techniques allowed for the reduction of applied radiation dose while maintaining image quality.

The aim of our educational exhibit is:

- to present optimal protocols for chest CT in the youngest age group of children, scanned according to body weight protocols (0-10kg; 10-30kg) with assesement of image quality and dose indices (CTDIvol and DLP; SSDE)

According to the current statistics, approximately 1 million children aged 6-14 participated in 11-payer football, more popular as youth football, in the 2021-2022 school year (3). A trend to earlier participation in specialized sports activities in pediatric patients has been observed. Contact sports such as basketball, football, and soccer comprise a considerable proportion of all played sports and are associated with the highest number of injuries, both acute and chronic in nature(9).
Lower extremities are the most common site of injury in pediatric football players, followed by upper extremity. Fractures and sprains/strains are the most common injury patterns (1, 9, 10). With the increasing number of young football athletes, there is a greater need to explore football-associated injuries, which can have a considerable physical, emotional, and psychosocial impact on a young individual.
This educational exhibit aims to explore the most common American football-related pediatric extremity injuries and their imaging characteristics using various modalities and briefly discuss the treatment options for the pediatric population. Read More

Developmental dysplasia of the hip (DDH) is a common congenital problem affecting up to 3% of the the population. If untreated, DDH may lead to hip dislocation and premature osteoarthritis. Current DDH diagnosis is highly operator-dependent as it relies on 2D ultrasound. 3D ultrasound offers more complete, and potentially more reliable, imaging of infant hip geometry. However, it is unclear whether 3D ultrasound images, noisy with artifacts and reconstructed by proprietary algorithms from non-parallel beams, give accurate 3D shape information. We sought to validate the fidelity of acetabular surface models obtained by 3D ultrasound by comparison with those obtained concurrently from MRI. Read More
