Tracheal agenesis is a rare and often lethal congenital defect that leads to airway emergency at birth. Computed tomography (CT) is the modality of choice to evaluate anomalous tracheal anatomy. The absence of spontaneous aeration of the tracheobronchial tree in children with tracheal agenesis makes CT interpretation difficult. We describe a procedure of airway management applied in two newborns with suspected tracheal agenesis. Correct airway management was performed immediately prior to CT examination by airway ventilation, with bag-valve mask alone in one case, and attached to an endotracheal tube placed into the esophagus in the other case...

Stephen J Lehnert, Matthew R Wanner, Boaz Karmazyn
BACKGROUND: Fishtail deformity is a rare deformity of the humerus exhibiting concavity of the lateral trochlea, resulting in ulnotrochlear joint derangement. We wanted to share our experience that osteochondritis dissecans of the capitellum is a common associated complication. OBJECTIVE: To summarize imaging of fishtail deformity in children centered on complications of the radiocapitellar joint. MATERIALS AND METHODS: From the radiology information system, we identified all patients <18 years with the diagnosis of fishtail deformity...

BACKGROUND: Because of its absence of ionising radiation and possibility for obtaining functional information, MRI is promising for assessing lung disease in children who require repetitive imaging for long-term follow-up. OBJECTIVE: To describe MRI findings in children with cystic fibrosis and evaluate semi-quantitative dynamic contrast-enhanced lung perfusion. MATERIALS AND METHODS: We retrospectively compared lung MRI in 25 children and young adults with cystic fibrosis (median age 3...

DIMITRA (dentomaxillofacial paediatric imaging: an investigation towards low-dose radiation induced risks) is a European multicenter and multidisciplinary project focused on optimizing cone-beam CT exposures for children and adolescents. With increasing use of cone-beam CT for dentomaxillofacial diagnostics, concern arises regarding radiation risks associated with this imaging modality, especially for children. Research evidence concerning cone-beam CT indications in children remains limited, while reports mention inconsistent recommendations for dose reduction...

Christian J Kellenberger, Thitiporn Junhasavasdikul, Mirkamal Tolend, Andrea S Doria
Contrast-enhanced magnetic resonance imaging (MRI) is considered the diagnostic standard for identifying involvement of the temporomandibular joint by juvenile idiopathic arthritis. Early or active arthritis is shown as bone marrow oedema, joint effusion, synovial thickening and increased joint enhancement. Subsequent joint damage includes characteristic deformity of the mandibular condyle, bone erosion, disk abnormalities and short mandibular ramus due to impaired growth. In this pictorial essay, we illustrate normal MRI findings and growth-related changes of the temporomandibular joint in children...

BACKGROUND: Nusinersen, the only treatment approved by the United States Food and Drug Administration for spinal muscular atrophy (SMA), is delivered intrathecally. Many children with SMA have extensive spinal instrumentation and deformities, often precluding the use of standard approaches for gaining intrathecal access. Furthermore the anatomical distortion that often occurs with rotoscoliosis can complicate the use of fluoroscopic guidance. Compared to fluoroscopy, CT affords superior guidance for complex needle placements...

BACKGROUND: Default pediatric protocols on many digital radiography systems are configured based on patient age. However, age does not adequately characterize patient size, which is the principal determinant of proper imaging technique. Use of default pediatric protocols by inexperienced technologists can result in patient overexposure, inadequate image quality, or repeated examinations. OBJECTIVE: To ensure diagnostic image quality at a well-managed patient radiation exposure by transitioning to thickness-based protocols for pediatric portable abdomen radiography...

Magnetic resonance imaging (MRI) often provides better visualization of bone marrow abnormalities than computed tomography (CT) or fluoroscopy, but bone biopsies are usually performed using conventional CT or, more recently, C-arm CT guidance. Biopsies of bone lesions solely visible on MRI are often challenging to localize and require the operator to review the MRI on a separate console to correlate with MRI anatomical landmarks during the biopsy. The MR overlay technique facilitates such biopsies in the angiographic suite by allowing the pre-procedural 3-D MRI to be overlaid on intraprocedural 2-D fluoroscopy...

We report a case of a 15-year-old boy with chronic intermittent left shoulder pain due to an undiagnosed lesser tuberosity avulsion fracture, an associated biceps pulley injury and intra-articular dislocation of the long head of the biceps tendon. Lesser tuberosity avulsion fractures are rare injuries that are difficult to detect on clinical exam and radiographically, which may lead to delayed diagnosis and chronic shoulder instability. Few reports describe dislocations or subluxations of the biceps tendon in association with lesser tuberosity avulsions in children...

BACKGROUND: Both [F-18]2-fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and diagnostic CT are at times required for lymphoma staging. This means some body segments are exposed twice to X-rays for generation of CT data (diagnostic CT + localization CT). OBJECTIVE: To describe a combined PET/diagnostic CT approach that modulates CT tube current along the z-axis, providing diagnostic CT of some body segments and localization CT of the remaining body segments, thereby reducing patient radiation dose...

BACKGROUND: Fibroadenoma is overwhelmingly the most common pediatric breast lesion. Breast malignancy is quite uncommon in children, most frequently metastatic or hematological malignancy. Core biopsy has largely replaced excision for diagnosis of breast masses in adults. OBJECTIVE: The purpose of this study is two-fold: (1) compare utilization at our institution of interventional procedures vs. surgery for breast mass diagnosis in patients ≤18 years and (2) propose guidelines for breast imaging and biopsy in this population...

BACKGROUND: Gonadal shielding remains common, but current estimates of gonadal radiation risk are lower than estimated risks to colon and stomach. A female gonadal shield may attenuate active automatic exposure control (AEC) sensors, resulting in increased dose to colon and stomach as well as to ovaries outside the shielded area. OBJECTIVE: We assess changes in dose-area product (DAP) and absorbed organ dose when female gonadal shielding is used with AEC for pelvis radiography...
