Degree Of Uncertainty In Reporting Imaging Findings For Necrotizing Enterocolitis: A Secondary Analysis From A Pilot Randomized Diagnostic Trial, Disa Rathore, Kira Bourrett, Sherwin S. Chan, Erin Opfer, Alain Cuna

Research Days

Background: Uncertainty in reporting of imaging findings for necrotizing enterocolitis (NEC) can be challenging for clinicians and result in ambiguity, miscommunication, and potential diagnostic errors. The degree to which uncertainty complicates diagnostic imaging for NEC has not been characterized.

Objective: To determine the degree of uncertainty in diagnostic imaging for NEC.

Methods: We conducted a retrospective study using data from a previously completed pilot diagnostic randomized clinical trial (RCT). The study population comprised of preterm infants with suspected NEC who were randomized to either standard imaging with abdominal radiographs (AXR) alone or experimental imaging with AXR + add-on bowel ultrasound …

Dislodged Endovascular Heat-Induced Thrombus Resulting In Pulmonary Embolus Following Post-Operative Ultrasound Compression, Danielle Park, Aghilas Belkadi, Luke Perry, Michael Kachmar, Holly Graves

Rowan-Virtua Research Day

Introduction: Venous insufficiency and consequent varicose veins are common problems faced by many patients. Fortunately, there are many treatment options available including a minimally invasive method known as radiofrequency ablation (RFA). RFA is not without complications; amongst those are endovascular heat induced thrombosis (EHIT). This rare complication is typically managed conservatively; however, in rare occasions, the thrombus can detach and embolize causing further issues for patients.

Case Description: A 48-year-old male underwent an uneventful RFA procedure for a CEAP 4a venous insufficiency. On the post-operative ultrasound venous duplex evaluation, the patient was found to have EHIT type 2 in the …

Case Report: Use Of Bedside Handheld Ultrasound To Diagnose Finger Dislocation, Frank Wheeler, Philip Carhart, James Espinosa, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Here we present the case of a 37-year-old male with a finger injury in which finger dislocation was suspected clinically. A bedside pocket ultrasound was performed using a water submersion technique, which identified a posterior dislocated right 2nd digit at the PIP joint. This finding was confirmed with an x-ray. This case report demonstrates that ultrasonography can be utilized to correctly identify finger dislocation. Although larger studies need to be performed to validate the accuracy of this imaging technique, the implications may improve care of the patient. It would also be particularly beneficial for this technique to be applied to …

The Application Of Point-Of-Care Ultrasound In Ed Intubations And Airway Access: A Systematic Review, Frank Wheeler, James Espinosa, Alan Lucerna, Jeffrey Gardecki

Rowan-Virtua Research Day

Intubation is an essential procedure performed on a routine basis in the emergency room. Unsuccessful intubations are associated with deleterious outcomes. A systematic review was performed to investigate the accuracy of point of care ultrasound (POCUS) in successful Endotracheal Tube (ET) tube confirmation, utilizing ultrasonography, identification of the cricothyroid membrane utilizing ultrasound, and dynamically during use of ultrasonography in the process of intubation. This review demonstrated high sensitivity and specificity for ultrasound confirmation of ET tube placement, high success rate in ultrasound-guided intubation, and lower than expected accuracy in identifying the cricothyroid membrane. Ultrasonography should be considered for ET tube …

Needs Assessment Of Pediatric Radiological Equipment And Cross-Cultural Investigation Into Parental Empowerment In Pediatric Radiology Program Development In The Kingdom Of Bhutan, Danielle Canter

GW Research Days 2016 - 2020

Background:

Bhutan is a magnificent mountainous country hugged by India to the east and west and by China to the North and South. This peaceful nestled country faces challenges in combating non-communicable diseases due to the lack of radiological equipment necessary for early diagnosis. Prior to implementation of these medical devices, it is imperative to investigate the cultural attitudes, beliefs, and infrastructure, to ensure successful integration. Bhutan is beginning to implement a pediatric radiology program for the nation with the assistance of ABAH Foundation and RAD-AID International, both of whom partnered with graduate students at George Washington University School of …

Difference Image Ultra-Short Echo Time T2* Mapping Using A 3d Cones Trajectory, Amin Nazaran, Grayson Tarbox, Randy Hartley, Neal Bangerter

Biomedical Engineering Western Regional Conference

This study introduces a methodology for detecting subtle variations in tissues with very rapid T2* decay through a difference image ultra-short T2* mapping technique using a 3D cones k-space trajectory. The new method is demonstrated in both a normal and surgically repaired Achilles tendon. The resulting UTE images are differenced and T2* values were calculated using a mono-exponential least squares fit on a voxel by voxel basis. The ultrashort T2* maps yield very consistent short T2* values in healthy tendon of 0.3-0.5 ms, while notable variations and elevations of T2* values are observed in surgically repaired tendon.
