1. Optic nerve sheath dilation, defined as greater than 5.0mm on ultrasound, had a high specificity for indicating elevated intracranial pressure, while less than 5.0mm had a high sensitivity to help rule out elevated intracranial pressures. 2. Patients presenting with a suspected traumatic brain injury and a positive ultrasound result...

Effect of Abdominal Ultrasound on Clinical Care, Outcomes, and Resource Use Among Children With Blunt Torso Trauma The focused assessment with sonography for trauma (FAST) exam is frequently used in the evaluation of injured adults, but little has been studied in children. In adults, the FAST exam has led to...
1. In a prospective study of over 570 children with appendicitis, ultrasound (US) is highly specific but not sensitive in the detection of appendix perforation. 2. Duration of symptoms, greater maximum diameter, simple and complex peri-appendiceal fluid, and the presence of an appendicolith was positively associated with appendix perforation. Evidence Rating...
1. In a retrospective review of over 96 000 children with acute appendicitis, there was a significant decrease in the utilization of computed tomography (CT) and a corresponding increase in ultrasound from 2005 to 2014. 2. Imaging costs for appendicitis have remained relatively constant over this period, while the proportion...
1. This meta-analysis found that for newborns presenting with jaundice, the triangular cord sign and abnormal gallbladder characteristics on ultrasound were most useful in the diagnosis or exclusion of biliary atresia. 2. The sensitivity and specificity for the combination of the triangular cord sign and gallbladder abnormalities for biliary atresia...
1. In patients with suspected appendicitis and equivocal ultrasound results, a low clinical score such as the Alvarado or Pediatric Appendicitis score was helpful in identifying patients with a low likelihood of disease. 2. Only slightly more than one-tenth of ultrasound examinations for appendicitis produced equivocal results, which could be...
1, Ultrasound can enhance the gastrointestinal delivery of drugs in porcine and rodent models through the cavitation of rectal tissue at low frequencies, increasing the permeability of the rectal and colonic tissues to multiple drugs, including macromolecules, without thermal or structural damage. Evidence Rating: 2 (good) Study Rundown:  Pathologies that affect...
1. Percutaneous drainage under ultrasonographic (US) or fluoroscopic guidance is a safe and effective treatment for patients with symptomatic pericardial effusion. 2. Drainage of posteriorly distributed pericardial effusions via a transhepatic approach is preferable to drainage using a subxiphoid or apical approach due to improved effusion accessibility. Evidence Rating Level: 2...
1. Ultrasound-guided cryoablation of invasive ductal carcinomas up to 15 mm in size was technically feasible, well-tolerated by patients, and largely clinically successful, as assessed by negative surgical margins following the procedure. However, a significant portion of patients had residual peripheral cancer. 2. Postablation contrast-enhanced magnetic resonance imaging was performed...
