Jacob L Rothermund, Andrew J Rabe, Nicholas A Zumberge, James W Murakami, Patrick S Warren, Mark J Hogan
BACKGROUND: Ballistic injuries with retained foreign bodies from air guns is a relatively common problem, particularly in children and adolescents. If not removed in a timely fashion, the foreign bodies can result in complications, including pain and infection. Diagnostic methods to identify the presence of the foreign body run the entire gamut of radiology, particularly radiography, ultrasound (US) and computed tomography (CT). Removal of the foreign bodies can be performed by primary care, emergency, surgical, and radiologic clinicians, with or without imaging guidance...

BACKGROUND: In pediatrics, contrast-enhanced ultrasound offers high-quality imaging with an excellent safety profile. OBJECTIVE: To investigate the effects of varying intravenous administration setups on in vitro enhancement and concentration of two commercially available ultrasound contrast agents, taking into consideration potential pediatric applications. MATERIALS AND METHODS: We quantified in vitro enhancement using a flow phantom (ATS Laboratories, Bridgeport, CT) and Acuson S3000 ultrasound system (Siemens Healthineers, Mountain View, CA) with a 9L4 probe in Cadence pulse sequencing mode...

Many orthopedic articles describe advances in surgical techniques and implants used in pediatric scoliosis surgery. However, even though postoperative spine imaging constitutes a large portion of outpatient musculoskeletal pediatric radiology, few, if any, radiology articles discuss this topic. There has been interval advancement over the last decades of the orthopedic procedures used in the treatment of spinal scoliosis in adolescents with idiopathic scoliosis. The goal of treatment in these patients is to stop the progression of the curve by blocking the spinal growth and correcting the deformity as much as possible...

BACKGROUND: Osteosarcoma is the most common pediatric malignant bone tumor, frequently surgically managed with limb salvage rather than amputation. Local recurrences are seen in up to 9% of osteosarcoma patients, with CT and MRI imaging often limited by metal artifacts. OBJECTIVE: To describe the [F-18]2-fluoro-2-deoxyglucose (FDG) PET/CT appearance of local osteosarcoma recurrences with correlation to findings on other imaging modalities. MATERIALS AND METHODS: A retrospective review of pediatric osteosarcoma patients imaged with FDG PET/CT was performed in patients with pathologically proven local recurrences...

BACKGROUND: The differential diagnosis for primary lung masses in neonates includes a variety of developmental abnormalities; it also consists of the much rarer congenital primary lung tumors: cystic pleuropulmonary blastoma (cystic PPB), fetal lung interstitial tumor (FLIT), congenital peribronchial myofibroblastic tumor (CPMT), and congenital fibrosarcoma. Radiologic differentiation between malformations and tumors is often very challenging. OBJECTIVE: The objective was to establish distinctive features between developmental pulmonary abnormalities and primary lung tumors...

BACKGROUND: Congenital vertical talus is a rare foot anomaly characterized by a prominent calcaneus and rigid forefoot dorsiflexion. While congenital vertical talus has been associated with anomalies such as trisomy 18, myelomeningocele and arthrogryposis, postnatal series have reported cases of isolated congenital vertical talus. OBJECTIVE: The purpose of our study was to determine the incidence of isolated congenital vertical talus prenatally and identify the most common anomalies associated with this finding...

BACKGROUND: Accurate evaluation of anatomy and ventricular function after the Norwood procedure in hypoplastic left heart syndrome is important for treatment planning and prognostication, but echocardiography and cardiac MRI have limitations. OBJECTIVE: To assess serial changes in anatomy and ventricular function on dual-source cardiac CT after the Norwood procedure for hypoplastic left heart syndrome. MATERIALS AND METHODS: In 14 consecutive patients with hypoplastic left heart syndrome, end-systolic and end-diastolic phase cardiac dual-source CT was performed before and early (average: 1 month) after the Norwood procedure, and repeated late (median: 4...

BACKGROUND: Normative data on pulmonary nodules in children without malignancy are limited. Knowledge of the frequency and characteristics of pulmonary nodules in healthy children can influence care decisions in children with malignant disease. OBJECTIVE: To provide normative data concerning the frequency and characteristics of pulmonary nodules on computed tomography (CT) in young children. MATERIALS AND METHODS: All children ages 1 year-12 years who underwent chest CT after high-energy trauma were retrospectively investigated...

REVIEW
Robert D MacDougall, Benoit Scherrer, Steven Don
This technical innovation describes the development of a novel device to aid technologists in reducing exposure variation and repeat imaging in computed and digital radiography. The device consists of a color video and depth camera in combination with proprietary software and user interface. A monitor in the x-ray control room displays the position of the patient in real time with respect to automatic exposure control chambers and image receptor area. The thickness of the body part of interest is automatically displayed along with a motion indicator for the examined body part...

BACKGROUND: There is a benefit in characterizing radiation-induced cancer risk in pediatric chest and abdominopelvic CT: a singular metric that represents the whole-body radiation burden while also accounting for age, gender and organ sensitivity. OBJECTIVE: To compute an index of radiation risk for pediatric chest and abdominopelvic CT. MATERIALS AND METHODS: Using a protocol approved by our institutional review board, 42 pediatric patients (age: 0-16 years, weight: 2-80 kg) were modeled into virtual whole-body anatomical models...

BACKGROUND: Pediatric providers should understand the basic risks of the diagnostic imaging tests they order and comfortably discuss those risks with parents. Appreciating providers' level of understanding is important to guide discussions and enhance relationships between radiologists and pediatric referrers. OBJECTIVE: To assess pediatric provider knowledge of diagnostic imaging modalities that use ionizing radiation and to understand provider concerns about risks of imaging...

Bonmyong Lee, Hansel J Otero, Matthew T Whitehead
BACKGROUND: The American College of Radiology (ACR) practice parameters for communication dictate that follow-up recommendations be suggested when appropriate. Radiologists assume that referring physicians read their reports and heed their advice. In reality, recommendations might not be carried out or even acknowledged. OBJECTIVE: We aimed to determine the proportion of imaging recommendations that are acknowledged and acted upon. MATERIALS AND METHODS: We conducted a retrospective review of all consecutive radiology reports containing "recommend" in the impression at a single academic children's hospital over a 1-month period...

Diagnosing childhood pulmonary tuberculosis (TB) may be challenging due to difficulties in obtaining adequate sputum samples, paucibacillary disease and the low sensitivity of diagnostic tests. Chest radiography is an important diagnostic tool for pulmonary TB, but it involves radiation exposure, requires facilities that can house X-ray equipment and has poor inter-reader agreement. The cardinal radiologic finding of mediastinal lymphadenopathy may be detected using mediastinal ultrasound (US). We describe technical aspects of performing mediastinal US, which may assist diagnosis of paediatric pulmonary TB...

BACKGROUND: Despite improving survival rates, children are at risk for long-term cognitive and behavioral difficulties following the diagnosis and treatment of a brain tumor. Surgery, chemotherapy and radiation therapy have all been shown to impact the developing brain, especially the white matter. OBJECTIVE: The purpose of this study was to determine the long-term effects of radiation therapy on white matter integrity, as measured by diffusion tensor imaging, in pediatric brain tumor patients 2 years after the end of radiation treatment, while controlling for surgical interventions...

BACKGROUND: Follicular bronchiolitis is a lymphoproliferative form of interstitial lung disease (ILD) defined by the presence of peribronchial lymphoid follicles. Follicular bronchiolitis has been associated with viral infection, autoimmune disease and immunodeficiency. The most common clinical manifestation is respiratory distress in infancy followed by a prolonged course with gradual improvement. We found no reports of systematic review of high-resolution computed tomography (HRCT) findings in pediatric follicular bronchiolitis...
