Evaluating Bone Fracture Healing Utilizing Novel Ultrasound Modes, X-Ray And Dual-Energy X-Ray Absorptiometry In A Rabbit Model, Priscilla Machado, Rachel Blackman, Ji-Bin Liu, Flemming Forsberg, Traci Fox

Department of Radiology Posters

Background and Purpose

Healing in bone fractures is a complex process involving local inflammation, angiogenesis (i.e., the creation of new blood vessels), and formation of a bone-building callus, all of which leads to returning the bone nearly to its pre-fracture state. This is the process in a bone where the fracture is clean and the fractured ends oppose each other. Five to 10 percent of fractures are described as non-union, which can lead to poor healing and long-term complications. The purpose of this study was to compare fracture healing in a rabbit model using x-ray, the traditional method for evaluating …

The Transition To Peer Learning, C. G. Roth, H. V. Naringrekar, A. E. Flanders

Department of Radiology Posters

Problem Description: Historically, peer review has been compelled by regulatory and legislative mandates, such as the Joint Commission Ongoing Professional Practice Evaluation (OPPE) requirement and the Health Care Quality Improvement Act (HCQIA) enacted by Congress in 1986. [1] However, these external mandates were focused on quality assurance, generally carrying punitive connotations and practically translated into rote compliance without the benefit of learning and improvement. In fact, the lack of quality improvement focus prompted the Institute of Medicine (IOM) to release its 2015 report, “Improving Diagnosis in Health Care,” stating that a “critical type of error in health care—diagnostic error—has received …

Purpose

To assess the efficacy of deep convolutional neural networks (DCNNs ) in differentiating acute aortic dissections from non-dissected aortas on thoracic CT.

Dti Metrics For Multi-Site/Multi-Scanner Study Of Adult Cervical Spinal Cord, Devon M. Middleton, Phd, Joshua Fisher, Bs, Adam E. Flanders, Md, Feroze Mohamed, Phd, John H. Wu, Md, Laura Krisa, Phd, Mark Elliot, Phd, Scott H. Faro, Md, Jessica Evans, Bs

Department of Radiology Posters

Background and Objective

A major variable in DTI spinal cord studies is the diversity in MRI scanner vendor and field strength. While there are several techniques proven to acquire DTI data, there are no standardized accepted methods for acquisition and processing. As more medical systems are utilizing this technology to evaluate the spinal cord, it is important to study the reproducibility of the DTI metrics among various scanner platforms, coil configurations and software implementations to determine the variance in obtaining normative spinal cord DTI data. This preliminary data for a multi-site DTI study examines the effects of these different MR …

“Step & Shoot” Cardiac Gated Ct For Detection Of Pulmonary Embolism: Technique And Advantages, Dinesh K. Sharma, Md

Department of Radiology Posters

Introduction

Pulmonary Embolism (PE) is a common condition with significant morbidity and mortality. Prompt recognition, diagnosis and management is important, as untreated PE complications are high; also treatment with long term anticoagulation has serious complications.

Pulse Shaping For Improved Diagnosis Of Portal Hypertension Using Subharmonic Aided Pressure Estimation, Ipshita Gupta, John R. Eisenbrey, Maria Stanczak, Anush Sridharan, Jaydev K.

Subharmonic aided pressure estimation (SHAPE) is based on the inverse relationship between the subharmonic amplitude of contrast microbubbles (obtained by transmitting at the fundamental frequency fo and receiving at fo/2) and the ambient pressure (see fig.1).

A noninvasive ultrasound based pressure estimation procedure would be a major development in the diagnosis of portal hypertension and less invasive than the current catheter-based hepatic venous pressure gradient (HVPG) measurement.

The hypothesis of this study was that portal vein pressures can be monitored and quantified noninvasively in humans using SHAPE.

First selected waveforms were optimized in vitro and in canines, then SHAPE was …

Conversion Of Intermediate Lirads Categories To Hepatocellular Carcinoma In Patients With Chronic Hepatitis B: Korean Immigrant Experience, Kofi-Buaku Atsina, Md, Zhenteng Li, Md, Sandeep Deshmukh, Md

Department of Radiology Posters

Introduction and Objective

The Liver Imaging Reporting and Data System (LIRADS) was created to standardize the reporting and data collection of MR imaging for hepatocellular carcinoma (HCC) in high risk patients. The major categories for LIRADS have the following descriptors:

LI-RADS 1 = Definitely benign

LI-RADS 2 = Probably benign

LI-RADS 3 = Intermediate probability for HCC

LI-RADS 4 = Probably HCC

LI-RADS 5 = Definitely HCC

LI-RADS 5V = Definitely HCC with tumor in vein

LI-RADS M = Probable malignancy, not specific for HCC

LI-RADS T = Treated Observation

However, there is a paucity of quantitative evidence for the …

Four-Dimensional (4d) Subharmonic Aided Pressure Estimation For Monitoring Neoadjuvant Chemotherapy Response Of Breast Cancer, Kibo Nam, Maria Stanczak, Anush Sridharan, Adam C. Berger, Tiffany Avery, John R. Eisenbrey, Flemming Forsberg

Department of Radiology Posters

Introduction

Neoadjuvant chemotherapy is a well-established treatment option for patients with non-metastatic breast cancer. The patient response is correlated with survival. However, the optimal method for monitoring neoadjuvant therapy response has not been established. One factor that may affect the response of neoadjuvant therapy is the interstitial fluid pressure (IFP). Increased IFP prevents an effective delivery of therapeutic agents and reduces the efficacy of the therapy. Recently, subharmonic-aided pressure estimation (SHAPE) using contrast-enhanced ultrasound (CEUS) has been developed and its potential was demonstrated in animals as a non-invasive technique for IFP measurements. The SHAPE method estimates IFP based on the …

Development Of A Temperature Sensitive Face Mask For Identification And Triage Of Febrile Patients, Annemarie Daecher, Flemming Forsberg, John R. Eisenbrey

Department of Radiology Posters

Abstract:

Many infectious diseases are most transmittable when the carrier is presenting with fever. We propose a disposable face mask that changes color as an indicator of fever to provide hospitals with a quick and inexpensive method for triaging infected patients while limiting exposure to others. Two blue thermochromatic dyes which transition to white at 89°F and 92°F were mixed with white paint and applied to 5 types of disposable face masks. During trials, a wearer either sat at rest or ran on a treadmill for 20 minutes and images were obtained every 5 minutes with a thermal camera to …
