BACKGROUND: De novo low-profile gastrojejunostomy tubes in pediatric patients offer less external catheter bulk and decreased propensity for dislodgement as children become more mobile. While small cohort studies have evaluated de novo placement of coaxial, adjustable-length, percutaneous gastrojejunostomy (GJ) tubes in children, placement of de novo low-profile GJ tubes in pediatric patients has not been analyzed. OBJECTIVE: This study evaluates technical feasibility, safety and clinical efficacy of percutaneous, retrograde placement of de novo low-profile GJ tubes in infants and children...

Minimally invasive procedures play a crucial role in the diagnosis and treatment of many pediatric musculoskeletal conditions. Although computed tomography and fluoroscopy are commonly used for image guidance, the associated exposure to ionizing radiation is especially concerning in pediatric patients. Ultrasonography may be used successfully in a subset of interventions, but it is often not useful for complex, deep, and osseous targets. Interventional magnetic resonance imaging (iMRI) facilitates targeting and treatment of musculoskeletal lesions at many locations with high accuracy due to its excellent tissue contrast...

BACKGROUND: American Academy of Orthopaedic Surgeons (AAOS) Clinical Practice Guidelines for pediatric femoral shaft fractures indicate titanium elastic nails (TENs) for children 5 to 11 years old. Growing evidence suggests these fractures may also be treated with open or submuscular plating. The purpose of this study was to compare estimated blood loss (EBL), operative time, fluoroscopy time, cost, and subjective and objective pain scores between TENs and plating techniques used in 5- to 11-year-old children with midshaft femur fractures based on length stability...

INTRODUCTION: Ureteroscopy has been shown to be a highly efficacious and safe modality for the treatment of pediatric urolithiasis. However, conventional ureteroscopy relies on fluoroscopy for intraoperative guidance, exposing both patient and operating room personnel to ionizing radiation. Pediatric urolithiasis patients are at a particularly increased risk from this radiation exposure. The use of ultrasound in place of fluoroscopy for intraoperative guidance has emerged as one modification that can reduce radiation exposure during ureteroscopy...

OBJECTIVES: In the pediatric population, there have been significant improvements in the treatment of stones in recent years. Conventionally, ureteroscopy (URS) and/or retrograde intrarenal surgery (RIRS) are techniques performed with fluoroscopy. When using fluoroscopy, problems, including malignancy, may arise due to radiation exposure in the patient, physician and operation room staff. The aim of this study is to evaluate the possibility of ureteroscopic treatment without fluoroscopy in children with ureteral and renal stones...

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...

BACKGROUND: Formal radiographs are frequently obtained after reduction of closed pediatric wrist and forearm fracture performed under mini C-arm fluoroscopy. However, their utility has not been clearly demonstrated to justify the increased time, cost, and radiation exposure. We hypothesized that formal postreduction radiographs do not affect the rereduction rate of pediatric wrist and forearm fractures. We further sought to determine the time, monetary, and opportunity costs associated with obtaining these radiographs...

Catheter ablation of cardiac arrhythmias in pediatric population is associated with the risk of ionizing radiation on the child. Due to a greater radiation sensitivity in children and a longer life expectancy newer techniques try to reduce the radiation exposure. A new technique for zero-fluoroscopy catheter ablation is described in a 9-year-old boy who had a left-sided concealed accessory pathway. The NAVX Ensite 3D mapping system permits catheter placement inside the venous system and movement inside the heart chambers without the use of X-rays...

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...
