Pediatric Emergency Magnetic Resonance Imaging: Current Indications, Techniques, and Clinical Applications.

MR imaging plays an important role in the detection and characterization of several pediatric disease entities that can occur in the emergent setting because of its cross-sectional imaging capability, lack of ionizing radiation exposure, and superior soft tissue contrast. In the age of as low as reasonably achievable, these advantages have made MR imaging an increasingly preferred modality for diagnostic evaluations even in time-sensitive settings. In this article, the authors discuss the current indications, techniques, and clinical applications of MR imaging in the evaluation of pediatric emergencies.

Pediatric Thoracic Organ Transplantation: Current Indications, Techniques, and Imaging Findings.

In the past decade, with improved surgical technique and knowledge of immunosuppression, pediatric lung and heart transplantation have been established as viable therapeutic interventions for pediatric patients with end-stage cardiopulmonary disease from various underlying congenital and acquired disorders. Although outcomes for pediatric patients are similar to those for adult patients, thoracic organ transplantation in this special age group carries unique challenges for preoperative and postoperative imaging evaluation. The article provides an up-to-date review of the postoperative transplant anatomy, imaging techniques, and complications of pediatric lung and heart transplantation.

Pediatric Abdominal Organ Transplantation: Current Indications, Techniques, and Imaging Findings.

The anatomy, normal postoperative radiological appearance, and imaging features of common postoperative complications of pediatric abdominal transplants are reviewed, including renal, liver, and intestinal transplants. Doppler ultrasound is the mainstay of imaging after transplantation. Computed tomography (CT) and CT angiography, MR imaging and magnetic resonance (MR) angiography, MR cholangiopancreatography, conventional angiography, and nuclear medicine imaging may be used for problem-solving in pediatric transplant patients.

Diagnostic errors of right lower quadrant pain in children: beyond appendicitis.

Right lower quadrant pain in children can result from various underlying conditions other than acute appendicitis. The common mimics of acute appendicitis are related to acute gastrointestinal and genitourinary diseases. Diagnosis of right lower quadrant pain in the pediatric population can be challenging, especially when the symptoms are often nonspecific.

Umbilical venous catheter malposition and errors in interpretation in newborns with Bochdalek hernia.

Background: Neonates with congenital diaphragmatic hernia (CDH) often require placement of lines and tubes for supportive therapy. The resulting altered anatomy can result in diagnostic errors when interpreting the location of support lines and tubes such as UVCs (umbilical venous catheters).

Objective: The purpose of this study was to evaluate the effect of CDH on UVC position and to evaluate the accuracy at which radiologists describe the position on chest radiographs.

An electronic tool for systematic reporting of fractures on skeletal surveys in suspected child abuse: prototype development and physician feedback.

Objective: To describe a skeletal survey data entry and compilation tool and assess physician attitudes toward this reporting approach.

Background: Narrative skeletal survey reports are highly variable and prone to inconsistencies with potential adverse impact on patients.

Materials And Methods: The prototype skeletal survey data entry and compilation tool was developed and introduced into clinical practice at a large urban children's hospital.

Extended outlook: description, utilization, and daily applications of cloud technology in radiology.

Objective: The purpose of this article is to discuss the concept of cloud technology, its role in medical applications and radiology, the role of the radiologist in using and accessing these vast resources of information, and privacy concerns and HIPAA compliance strategies.

Conclusion: Cloud computing is the delivery of shared resources, software, and information to computers and other devices as a metered service. This technology has a promising role in the sharing of patient medical information and appears to be particularly suited for application in radiology, given the field's inherent need for storage and access to large amounts of data.

Cybersecurity in radiology: Access of public hot spots and public Wi-Fi and prevention of cybercrimes and HIPAA violations.

Objective: The purpose of this article is to review the steps that can be taken to ensure secure transfer of information over public and home networks, given the increasing utilization of mobile devices in radiology.

Conclusion: With the rapid technologic developments in radiology, knowledge of various technical aspects is crucial for any practicing radiologist. Utilization of mobile devices, such as laptops, tablets, and even cellular phones, for reading radiologic studies has become increasingly prevalent.

Abnormal MIBG uptake in a neuroblastoma patient with right upper lobe atelectasis.

A 3-month-old boy with a history of an abdominopelvic neuroblastoma presented 1 week after tumor resection for a routine follow-up 123-I Meta-iodobenzylguanidine (MIBG) scan to assess for residual mass. The study demonstrated abnormal radiotracer uptake in the right upper lobe, which correlated on the SPECT/CT to an area of airspace consolidation thought to be secondary to atelectasis. To the best of our knowledge, there is one published case of MIBG radiotracer uptake in the lung correlating with pneumonia; however, there are no reported cases to date in the literature of focal pulmonary MIBG uptake corresponding to atelectasis.
