The Relevance Of More Training Data On Accuracy Of Model Prediction On Chest X-Ray, Ardenne S. Martin, Carl F. Sabottke, Bradley M. Spieler

Medical Student Research Poster Symposium

Background: Artificial Intelligence (AI) has the potential to augment radiologist workflow and decrease strain on radiologists. Development of deep neural networks, artificial neural networks with neurons, synapses, weights, and functions, can be used to train AI models, serving as a response to this need. Publicly available databases like MIMIC-CXR and ChestX-ray8 offer hundreds of thousands of chest x-rays (CXR) used to train neural network models to detect and localize devices or disease. These publicly available databases make training AI models on large datasets possible. Once models are aptly trained, however, challenges include implementation into hospital Picture Archiving and Communication Systems …

Effects Of Breast Cancer Screening Guidelines: A Retrospective Analysis Ofbreast Cancer Patients Under Age 50 In A University Academic Center, Kaylee Woodard, Jane Ball, Brooke Morrell

Medical Student Research Poster Symposium

In 2009, the U.S. Preventative Services Task Force (USPSTF) released updated breast cancer screening guidelines recommending against routine screening mammography in women aged 40-49. The task forceconcluded that the decision to start regular, biennial screening mammography before age 50 years should be an individual one considering patient context, including the patient's values regarding specific benefits and potential harms. In January 2016, the USPSTF reinforced these guidelines in their Final Recommendation Statement grading screening mammography prior to age 50 as a Grade C, stating there is at least moderate certainty that the net benefit is small. Despite the USPSTF’s findings, it …

Infection Imaging, Techniques And Trends: A Radiology Research Alliance (Rra) Taskforce Report, Claire Bise, Prabhakar Rajiah

Medical Student Research Poster Symposium

Infectious diseases are caused by a wide spectrum of organisms and can present in myriad fashion. They are important contributors to morbidity and mortality. While some infections are localized to specific organs, others can cause systemic illness. Identification of source of infection is a very important step in the management of infections but may be occasionally challenging due to non-specific symptoms and signs. Imaging plays an important role in the diagnosis and localization of infection. Several anatomical and functional imaging modalities are available, with the choice of specific imaging modality dependent on the clinical presentation as well as availability of …

Comparing Semi-Automated Segmentation Of Traditional-Resolution And High-Resolution Hyperpolarized 129xe Mri On Covid-19 Survivors, Tingting Wu

Undergraduate Student Research Internships Conference

Hyperpolarized gas MRI using inert gases like Xe is a valuable tool in visualizing lung ventilation in patients, and can be used as a longitudinal monitoring tool for patients with lung diseases. However, use of this method requires segmentation and quantification of parameters such as ventilation defect percentage (VDP), which is often very subjective depending on the observer. This study aimed to determine the accuracy and consistency of VDP calculation using the same MRI scans from COVID-19 patients, but with high resolution and low (traditional) resolution versions. Using a MATLAB script developed previously, it was found that in general, using …

Pediatric Pulmonary Artery Aneurysms Causing Pulmonary Hemorrhage: A Case Of Transcatheter Intervention While On Va Ecmo Support, Igor Areinamo

Research Days

Background: The incidence of pulmonary artery aneurysm (PAA) in children remains unknown. There are few reports of a transcutaneous interventional approach to address this type of pathology. Management of PAAs while on VA ECMO has not been described in pediatrics.

Objectives/Goal:

Methods/Design:

Case: 9-year-old previously healthy male presented with MRSA associated ARDS and sepsis requiring urgent VA ECMO cannulation. Chest CT done on ECMO day 22 showed development of right sided PAAs. Patient had an episode of significant pulmonary hemorrhage. Angiogram demonstrated two fusiform right PAAs, one of which had ruptured and was bleeding into the lung parenchyma. Patient had …

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 …
