OBJECTIVES: Neurologic deterioration associated with cerebral edema in diabetic ketoacidosis is typically sudden in onset, progresses rapidly, and requires emergent treatment. The utility of brain imaging by head CT in decisions to treat for cerebral edema has not been previously studied. The objective of this study was to describe the characteristics of pediatric patients with diabetic ketoacidosis who develop altered mental status and evaluate the role of head CT in this cohort. DESIGN: Retrospective analysis of clinical, biochemical, and radiologic data...

Children feature more active cellular division and a smaller body area, which leads to a greater radiation dosage accumulation. We tried to reduce radiation hazards by reducing unnecessary radiological studies in a pediatric emergency department (PED) through the radiation reduction campaign.Our campaign involved a reduction from 2 (erect and supine) to 1 ordered abdominal plain radiograph (erect). This quasi-experimental, uncontrolled before-and-after study aimed to evaluate the campaign effect. We compared simple radiograph orders, length of stay (LOS) in PED, and return visit (RV) to PED between the before period (June 1, 2011-May 30, 2014) and the after period (June 1, 2014-May 30, 2015)...

INTRODUCTION: Spontaneous pneumothorax in pediatric patients is relatively uncommon. The management strategy varies in different centers due to dearth of evidence-based pediatric guidelines. In this study, we reviewed our experience of thoracoscopic management of primary spontaneous pneumothorax (PSP) in children and identified risk factors associated with postoperative air leakage and recurrence. MATERIALS AND METHODS: We performed a retrospective analysis of pediatric patients who had PSP and underwent surgical management in our institution between April 2008 and March 2015...

OBJECTIVE: The purpose of this study is to determine the conversion factors that enable accurate estimation of the effective dose (ED) used for cardiac 64-MDCT angiography performed for children. MATERIALS AND METHODS: Anthropomorphic phantoms representative of 1- and 10-year-old children, with 50 metal oxide semiconductor field-effect transistor dosimeters placed in organs, underwent scanning performed using a 64-MDCT scanner with different routine clinical cardiac scan modes and x-ray tube potentials...

OBJECTIVES: The estimation of skeletal maturity is a useful tool in pediatric practice to determine the degree of delay or advancement in growth disorders and the effectiveness of treatment in conditions that influence linear growth. Skeletal maturity of children is commonly assessed using either Greulich-Pyle (GP) or Tanner-Whitehouse methods (TW2 and TW3). However, a less invasive ultrasonic method, that does not use ionizing radiation, has been suggested for use in epidemiological studies of skeletal maturity...

BACKGROUND: Our aim was to study long-term clinical and radiologic outcome of children with parenchymal neurocysticercosis (NCC) and its predictors. METHOD: 500 children with NCC registered in the pediatric NCC Clinic between January 1996 and December 2002 and followed to December 2009 were enrolled. Demographic details, clinical presentations and therapy received were recorded. Outcome was evaluated in terms of seizure recurrence and resolution of lesions on neuroimaging...

BACKGROUND: Self-balancing electric scooters, commonly known as hoverboards, are a new and popular consumer item with recognized fall hazards. The spectrum of injuries associated with hoverboard use has not been studied. OBJECTIVE: The purpose of this study is to determine the spectrum of radiologically apparent injuries associated with hoverboard use.

: Radiation dose monitoring solutions have opened up new opportunities for medical physicists to be more involved in modern clinical radiology practices. In particular, with the help of comprehensive radiation dose data, data-driven protocol management and informed case follow up are now feasible. Significant challenges remain however and the problems faced by medical physicists are highly heterogeneous. Imaging systems from multiple vendors and a wide range of vintages co-exist in the same department and employ data communication protocols that are not fully standardized or implemented making harmonization complex...

PURPOSE: Epidemiological studies of second cancer risk in radiotherapy patients often require individualized dose estimates of normal tissues. Prior to 3D conformal radiation therapy planning, patient anatomy information was mostly limited to 2D radiological images or not even available. Generic patient CT images are often used in commercial radiotherapy treatment planning system (TPS) to reconstruct normal tissue doses. The objective of the current work was to develop a series of reference size computational human phantoms in DICOM-RT format for direct use in dose reconstruction in TPS...

PURPOSE: To bring together radiologists, technologists, and physicists to utilize post-processing techniques in digital radiography (DR) in order to optimize image acquisition and improve image quality. METHODS: Sub-optimal images acquired on a new General Electric (GE) DR system were flagged for follow-up by radiologists and reviewed by technologists and medical physicists. Various exam types from adult musculoskeletal (n=35), adult chest (n=4), and pediatric (n=7) were chosen for review...

Myxopapillary ependymoma (MPE) is a slow-growing tumor occurring most often in adults. It originates from the filum terminale in the area of the conus medullaris and cauda equina, and is considered a benign lesion. Despite this classification, however, recurrence after both partial and gross total resection is well known. In the pediatric population, primary MPE seeding is well documented and treated through gross total resection, followed by irradiation. In adults, however, primary MPE seeding is not recognized...

Pediatric sensorineural hearing loss is a major cause of disability; although inner ear malformations account for only 20-40% of all cases, recognition and characterization will be vital for the proper management of these patients. In this article relevant anatomy and development of inner ear are surveyed. The role of neuroimaging in pediatric sensorineural hearing loss and cochlear preimplantation study are assessed. The need for a universal system of classification of inner ear malformations with therapeutic and prognostic implications is highlighted...

Bithalamic gliomas are rare cancers diagnosed based on poorly defined radiologic criteria. Infiltrative astrocytomas account for most cases. While some previous studies reported dismal outcomes for patients with bithalamic gliomas irrespective of therapy and histologic grade, others described better prognoses even without anticancer therapy. Little is known about their molecular characteristics. We reviewed clinical, radiologic, and histologic features of patients with bithalamic gliomas treated at our institution over 15 years...
