Extra Axial Chordoma Of The Distal Femoral Metaphysis: A Case Report, Long Nguyen, Irene Vasko Do, Gord G. Zhu Do, Veniamin Barshay Md, Ms, Phd

Cooper Rowan Medical Journal

Background

Chordomas are malignant bone tumors that are derived from remnant embryonic tissue of the notochord and are typically found in the axial midline. When they are found outside of the axial skeleton, the diagnosis can be challenging and elusive. Often, they are overlooked on initial presentation in lieu of other more common lesions, including cartilage tumors (eg, enchondroma, chondrosarcoma, osteochondromatosis) due to their overlapping features.

Case Report

A 30-year-old female with a four-year history of intermittent left knee pain presented for initial evaluation. Physical exam of the knee was unremarkable except for moderate tenderness on palpation. Radiographs showed a …

Development Of A Ct Metal Artifact Management Algorithm For Proton Therapy Planning (Ampp) For Head And Neck Cancer Patients, Daniela Branco

Dissertations & Theses (Open Access)

Purpose: Dental amalgams (high Z materials) are common sources of artifacts in Head and Neck (HN) images. Commercial artifact reduction techniques have been offered, but many are impractical, produce inaccurate CT images or are not clinically available, thus not widely implemented. The goal of this work is to use CT gantry tilts to develop and evaluate a stereoscopic HN metal artifact management algorithm and investigate its improvement in proton treatment planning.

Methods: The in-house CT metal artifact management method for proton planning (AMPP) uses two angled CT scans to generate a single image set with no metal artifacts posterior …

Mechanical Thrombectomy For Acute Ischemic Stroke In The Cardiac Catheterization Laboratory., Steven A Guidera, Sudhir Aggarwal, J Doyle Walton, David Boland, Roy Jackel, Jeffrey D Gould, Brooke Kearins, Joseph Mcgarvey, Yan Qi, Brian Furlong

Department of Radiology & Diagnostic Medical Imaging

OBJECTIVES: The aim of this study was to determine the feasibility of establishing a mechanical thrombectomy (MT) program for acute ischemic stroke in a community hospital using interventional cardiologists working closely with neurologists.

BACKGROUND: American Heart Association/American Stroke Association 2018 guidelines give a Class I (Level of Evidence: A) recommendation for MT in eligible patients with large vessel occlusion stroke. Improvement in neurological outcomes with MT is highly time sensitive. Most hospitals do not have trained neurointerventionalists to perform MT, leading to treatment delays that reduce the benefit of reperfusion therapy.

METHODS: An MT program based in the cardiac catheterization …

Development Of Gaussian Learning Algorithms For Early Detection Of Alzheimer's Disease, Chen Fang

FIU Electronic Theses and Dissertations

Alzheimer’s disease (AD) is the most common form of dementia affecting 10% of the population over the age of 65 and the growing costs in managing AD are estimated to be $259 billion, according to data reported in the 2017 by the Alzheimer's Association. Moreover, with cognitive decline, daily life of the affected persons and their families are severely impacted. Taking advantage of the diagnosis of AD and its prodromal stage of mild cognitive impairment (MCI), an early treatment may help patients preserve the quality of life and slow the progression of the disease, even though the underlying disease cannot …

Us Guided Management Of Undifferentiated Dyspneic Patient In The Ed, Kaleigh Miller

Longitudinal Scholar's Project

Intro: Undifferentiated dyspnea can be a complicated presentation muddled by patient comorbidities and similar symptomology shared among etiologies. Some studies have shown increased mortality and length of stay in the hospital when incorrectly initially diagnosed in the ED. US has been shown more effective at differentiating these causes and improves diagnostic accuracy. This study will implement US exam upon initial exam of patient and chart time to diagnosis/treatment, length of stay in ED, length of stay in hospital admissions versus discharge rates, and 30 day mortality. ADHF and COPD/asthma patient differentiation will be the focus.

Methods: Prospective cohort study of …

Optimal Multi-Stage Arrhythmia Classification Approach, Jianwei Zhang, Huimin Chu, Daniele Struppa, Jianming Zhang, Sir Magdi Yacoub, Hesham El-Askary, Anthony Chang, Louis Ehwerhemuepha, Islam Abudayyeh, Alexander Barrett, Guohua Fu, Hai Yao, Dongbo Li, Hangyuan Guo, Cyril Rakovski

Arrhythmia constitutes a problem with the rate or rhythm of the heartbeat, and an early diagnosis is essential for the timely inception of successful treatment. We have jointly optimized the entire multi-stage arrhythmia classification scheme based on 12-lead surface ECGs that attains the accuracy performance level of professional cardiologists. The new approach is comprised of a three-step noise reduction stage, a novel feature extraction method and an optimal classification model with finely tuned hyperparameters. We carried out an exhaustive study comparing thousands of competing classification algorithms that were trained on our proprietary, large and expertly labeled dataset consisting of 12-lead …

A 12-Lead Electrocardiogram Database For Arrhythmia Research Covering More Than 10,000 Patients, Jianwei Zhang, Jianming Zhang, Sidy Daniako, Hai Yao, Hangyuan Guo, Cyril Rakovski

Mathematics, Physics, and Computer Science Faculty Articles and Research

This newly inaugurated research database for 12-lead electrocardiogram signals was created under the auspices of Chapman University and Shaoxing People’s Hospital (Shaoxing Hospital Zhejiang University School of Medicine) and aims to enable the scientific community in conducting new studies on arrhythmia and other cardiovascular conditions. Certain types of arrhythmias, such as atrial fibrillation, have a pronounced negative impact on public health, quality of life, and medical expenditures. As a non-invasive test, long term ECG monitoring is a major and vital diagnostic tool for detecting these conditions. This practice, however, generates large amounts of data, the analysis of which requires considerable …

Pediatric Chest X-Rays, Liam Du Preez

Larner College of Medicine Fourth Year Advanced Integration Teaching/Scholarly Projects

Chest Radiographs are the most commonly ordered diagnostic image in the pediatric population. These images are encountered often in both the early medical school curriculum and outside in the clinical setting. This module was generated with the goals of giving a framework for approaching pediatric chest x-rays, as well as showcasing common radiographic findings, both normal and pathologic.

Lead X-Ray Vests: Pros And Cons In Dental Radiography And Patient Education On Radiographic Technology, Kayla D. Oakley, Emily Deker

Dental Hygiene Student Scholarship

Problem: There is a greater need to emphasize and educate patients and providers about radiologic advancements and patient exposure. The tradition of placing lead x-ray vests on patients for all radiographs is no longer a necessity. Without the explanation of why lead aprons are no longer needed, unnecessary steps for the provider and potential harm to the patient could be caused.

Methods: This review of literature was assembled by analyzing data from primary and secondary sources through online databases. The most recent research on the risks and benefits of the use of lead x-ray vests towards patients in …

Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer

Capstone Showcase

ABSTRACT

Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey …
