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

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.

Ischial tuberosity avulsion fractures, though not uncommon in adolescent athletes, are often overlooked or misdiagnosed. These fractures occur more frequently in males than females. Primary cause of this fracture type is usually a sudden eccentric load on the proximal hamstrings, typically seen during a kicking action in dance, football, or soccer. Due to the limited use of imaging in the evaluation of such injuries, these fractures often are misdiagnosed or underdiagnosed. Recent injuries warrant more conservative management, including rest and relative immobilization. In cases of late diagnosis, delayed healing, or persistent symptomatology, surgical intervention can be undertaken to restore normal anatomy, alleviate symptoms, and facilitate healing. Minimally invasive CT-guided percutaneous needle fenestration has been introduced for symptomatic delayed union ischial tuberosity fractures in adolescents. This percutaneous procedure involves the creation of multiple channels into the bone at the fracture site with an 18 gauge Chiba needle via image guided needle fenestration to enhance blood flow and promote healing of the target area. Following this, a tailored physical therapy program is implemented based on patient symptomatology, individual tissue healing rates, and the current literature related to proximal hamstring injuries. Outcomes to this minimally invasive approach have been promising including cases of complete pain relief, full functional recovery, and a return to sports without limitations.
Outline of Teaching Points:
Ischial tuberosity avulsion fractures are common in adolescent athletes, with a higher incidence in males, caused by sudden eccentric loads on proximal hamstrings during activities like dance, football, or soccer.
Due to limited imaging use, these fractures are often overlooked or misdiagnosed, leading to delayed healing or persistent symptoms.
Recent injuries may benefit from conservative management, involving rest and relative immobilization.
Surgical intervention becomes necessary for late diagnoses, delayed healing, or persistent symptoms to restore normal anatomy and alleviate symptoms.
Minimally invasive CT-guided percutaneous needle fenestration has shown promising outcomes, facilitating healing with complete pain relief and a return to sports without limitations.

The practice of performing dedicated breast ultrasounds in the pediatric emergency department varies according to institution. In the adult population, breast ultrasounds are commonly interpreted by dedicated breast imagers and/or radiologists appropriately qualified to interpret mammograms. Children's hospitals with dedicated pediatric radiology faculty are less likely to have such individuals on staff. This paper examines the practice of breast ultrasounds ordered in the emergency department throughout a large children's health system. 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

International clinical observerships in pediatric radiology offer benefits such as academic collaboration and brand recognition. However, they also introduce additional administrative burden, scheduling difficulties, increased faculty workload for the host institution, and regulatory and financial challenges for observers. In January 2021, the observer program at a US-based teaching hospital's radiology department was relaunched following a COVID-19 pandemic hiatus, providing a limited number of scholarships to medical students, residents, fellows, and other colleagues worldwide for 1-6 weeks. During their stay, observers rotated through different divisions, accessed our learning management system (LMS), and were encouraged to attend conferences and to give a lecture or case-based presentation to the department. We aim to evaluate the effectiveness of the program and the impact on the observer’s career. Read More

Introduction:
Fluoroscopy plays an important role in pediatric diagnostic imaging. However, its use has been replaced by other imaging modalities for some applications. While fluoroscopy offers dynamic evaluations of the airway, gastrointestinal tract, and urinary system, multiple barriers exist. It is an operator-dependent modality that requires expertise and additional training. Furthermore, concerns for radiation exposure and lower reimbursement rates exist, which add safety and financial disincentives. This educational exhibit provides a side-by-side comparison of traditional fluoroscopic studies and their replacement modalities.
Fluoroscopy applications and their alternatives:
Respiratory system:
Foreign body aspiration: Radiography or CT
Tracheomalacia: CT
Diaphragmatic motion: Ultrasound or MRI
Gastrointestinal Tract:
Esophageal foreign body: Radiography
Gastrostomy tube dislodgement: Radiography
Upper GI (Malrotation and volvulus): Ultrasound
Enema for intussusception reduction: Ultrasound guided reduction
Enema for Hirschsprung diagnosis: Contrast radiograph
Urinary Tract:
Voiding cystourethrograms (VCUG): Contrast-enhanced vesicourethrosonography (CeVUS)

Artificial intelligence (AI) has the potential to improve many aspects of pediatric radiology. AI solutions have emerged to perform a wide range of tasks, including facilitating the workload of radiologists, improving image quality, performing motion correction, and reducing contrast dose. While a myriad of courses for learning AI are available, most resources lack the necessary radiology perspective required for clinical application. Few interactive resources are available to teach a systematic approach for pediatric radiologists when analyzing AI literature. Since AI methodologies in pediatric radiology research fundamentally differ from classical statistical analyses, an educational poster dedicated to interpreting pediatric radiology AI literature would assist in bridging this gap.
The purpose of this education exhibit is to provide a resource for pediatric radiologists that teaches a systematic approach for the interpretation of AI research publications. Knowledge delivery will be made by eLearning slide-based presentation. The major topics regarding AI literature will focus on: problem identification; data curation; data annotation, artificial intelligence models; validation and performance. Next, we review prior literature on important criteria for AI publications, including Checklist for Artificial Intelligence in Medical Imaging (CLAIM), the AI version of the Standards for Reporting of Diagnostic Accuracy Studies (STARD-AI), Transparent Report of Multivariable Prediction Model of Individual Prognosis and Diagnosis for AI (TRIPOD-AI) and Prediction Model Risk of Bias Assessment Tool for AI (PROBAST-AI). Lastly, we present these criteria in the context of pediatric AI research applications.
AI research methodology in pediatric radiology differs from classical research methodologies. Therefore, this education exhibit is intended to teach the systematic interpretation of the primary AI literature to pediatric radiologists in order to translate scientific knowledge into meaningful clinical information.

PTEN-related hamartoma tumor syndromes (PHTS) arise from germline pathogenic variants in the Phosphatase and Tensin homolog (PTEN) gene and include a broad spectrum of autosomal dominant clinical phenotypes with overlapping features. Its diagnosis is made through genetic testing prompted by family history or clinical features. In pediatric patients the most common feature leading to genetic testing is macrocephaly, in combination with other clinical findings, presenting in early childhood.
PHTS is a multisystem disorder. Imaging findings on pediatric patients have a wide variability, but benign findings are the most common.
In this educational exhibit, we will summarize the imaging findings of pediatric patients with confirmed PTEN diagnosis, based on our experience from three large children’s hospitals.
The most common findings will be described by anatomical regions:
- Central nervous system: white matter lesions, prominence of perivascular spaces, prominence of the ventricles and extra-axial spaces, and a dysplastic gangliocytoma of the cerebellum.
- Thyroid/neck: benign lesions such as nodular goiter, follicular adenomas, colloid cysts, and features of thyroiditis and pediatric thyroid carcinoma.
- Chest/mediastinum: infrequent lesions such as sclerosing pneumocytoma or chest wall lesions.
- Nonvascular soft tissue masses: variable types of hamartomas including polyps, fibromas, and lipomas.
- Vascular soft tissue masses: hemangiomas and classic PTEN hamartoma of the soft tissues (PHOST).
At the end of our exhibit, we will include current suggested surveillance imaging protocol for these patients.

Advocacy is the act of supporting or defending a specific cause or issue, with the aim of raising public awareness, garnering support, or influencing policy. Traditionally, it has not been included in the pediatric radiology training curriculum or regarded as a conventional academic pursuit. However, we believe it to be a vital aspect of a pediatric radiologist, regardless of their rank or clinical setting. Research efforts can provide support and validate for advocacy processes by generating evidence and measuring their impact and outcomes. We consider that encouraging these efforts is essential for “demystifying’ and better integrating it into academic life. Read More

Brain death, also known as death by neurologic criteria, (BD/DNC) is the permanent loss of total brain function in individuals who have sustained catastrophic brain injuries. Accounting for approximately 5% of pediatric deaths, BD/DNC remains a clinical diagnosis, which is often emotionally laden and not always straightforward. When results are equivocal or there exist limitations to the safe completion of the clinical assessment, clinicians rely on ancillary testing to make informed decisions. In October 2023, updated adult and pediatric BD/DNC consensus guidelines were published which reinforce differences in the recommendations for testing between the adult and pediatric populations. It is, therefore, crucial for Pediatric Radiologists to understand these guidelines and the critical role radiology plays in supporting this important diagnosis.
In this educational exhibit, we will review the recent consensus guidelines and clinical indications for the use of imaging in BD/DNC evaluation. We will provide a step-by-step guide which will include patient preparation, radionuclide or contrast administration, image acquisition, and image interpretation for the two validated methods of pediatric BD/DNC ancillary testing: Radionuclide Perfusion Scintigraphy and 4-Vessel Catheter Angiography.
Although 4 vessel catheter angiography is considered the gold standard in ancillary BD/DNC testing, as it is believed to be both 100% sensitive and 100% specific, radionuclide scintigraphy is the more widely used modality in the pediatric population, owing to the less invasive nature of the exam. Neither exam is without challenges related to limited availability and technical skill required yet are currently the only validated radiologic tools recommended for use in brain death diagnosis. Our exhibit will review multiple cases of evaluation for BD/DNC, accentuating imaging findings and pearls/pitfalls of acquisition and interpretation. Opportunities for investigation of other available imaging techniques will also be highlighted.

Female conjoined throraco-omphalopagus twins were delivered via cesarean section at 35 weeks 5 days gestational age to a 38-year-old mother who received standard prenatal care. After resuscitation, the twins were transferred to the neonatal ICU, where they remained for monitoring and growth as they were assessed for potential separation.
CT angiography was performed at 3-4 months of life using a staged approach. Selective IV and oral contrast administration was used over two visits to delineate shared and non-shared structures. Most significantly, there was a single shared liver with anomalous hepatic venous drainage. Twin A had three normal caliber hepatic veins draining into a normal IVC, but a large branch of the middle hepatic vein traversed midline into Twin B and received hepatic venous drainage from Twin B via numerous anomalous vessels. Twin B had a normal IVC but three diminutive hepatic veins, thought to be due to reduced venous drainage as a result of the anomalous shared vasculature.
After multidisciplinary discussion, interventional radiology was consulted for hepatic venogram and intervention as needed. The anomalous communicating vessels were identified on hepatic venogram via Twin A femoral approach. Occlusion of the anomalous branches was achieved with serial embolization of the primary draining vessel on the Twin A side using Amplatzer vascular plugs. Successful occlusion was confirmed on venography after the final embolization procedure.
Follow-up Doppler ultrasound exams confirmed improved hepatic venous outflow in Twin B, initially with reversal of flow in the anomalous veins back toward the IVC of Twin B, followed by nonvisualization of the anomalous veins on later exams. CT angiography later showed enlarged caliber of the native Twin B hepatic veins. Following the optimization of hepatic venous outflow, the multispecialty surgical team proceeded with separation. The twins were separated at 13 months of age without complication. In addition to restoring venous outflow to allow for a successful surgical outcome, it was noted that the Amplatzer devices were used as surgical landmarks during separation for identification of shared anatomy. Through careful planning and execution, diagnostic and interventional radiology techniques played a critical role in this successful outcome.

Ocular ultrasound is an excellent tool for diagnosing and monitoring pediatric patients, delivering a reliable assessment and clear visualization of ocular anatomy. It can provide information about ocular irrigation and, consequently, the alterations in ocular pathology that would otherwise be difficult to assess. It is essential that radiologists possess a comprehensive understanding of the anatomy of the eye and understand the different changes associated with various eye diseases. Familiarity with the protocol of these images is crucial for effectively detecting and diagnosing these pathologies. Nevertheless, it's important to recognize ocular ultrasound's limits, especially in extraocular malignancies and orbital pathologies, which may be more appropriately evaluated using alternative imaging techniques.
With this in mind, this exhibit aims to teach about pediatric ocular pathologies and how they can be identified using ultrasound. In addition, through imaging cases, recognize the characteristic ultrasound findings for each pathology:
- Retinal detachment
- Congenital cataracts
- Proliferative Vascular Retinopathy of Prematurity
- Retinoblastoma
- Choroidal hemangioma
- Papilledema
