Department of Radiology & Diagnostic Medical Imaging

We share our experience with serial PET/CT imaging on a patient with extranodal Rosai-Dorfman disease (RDD) with hepatopancreatic involvement. RDD is a benign proliferative disorder of histiocytes mainly involving the lymph nodes. It typically presents with fever and painless cervical lymphadenopathy in young adults and less than half of RDS cases demonstrate extranodal involvement. RDD involvement of the liver and pancreas is extremely rare, and this case highlights the role of PET/CT in its management.

Oncology Section Edge Task Force On Breast Cancer Outcomes: A Systematic Review Of Outcome Measures For Functional Mobility, Mary Insana Fisher, Jeannette Lee, Claire Davies, Hannah Geyer, Genevieve Colon, Lucinda Pfalzer

Mary Insana Fisher

Background: Breast cancer treatments in women with breast cancer often result in physical impairments that lead to activity limitations and participation restrictions. These limitations and restrictions manifest in impaired functional mobility skills that may impact survivorship. Thus, evaluation of functional mobility is an important part of survivorship care. Purpose: To identify functional mobility outcome measures that possess strong psychometric properties and are clinically useful for examination of women treated for breast cancer. Methods: Multiple electronic databases were searched for articles published after 1995. Studies were included if they reported psychometric properties, used clinically feasible methods, were performed on adults, and …


Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, Paul G. Peters, Michael A. Herbenick, Philip A. Anloague, Ronald J. Markert, L. Joseph Rubino Dec 2015

Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, Paul G. Peters, Michael A. Herbenick, Philip A. Anloague, Ronald J. Markert, L. Joseph Rubino

Philip A. Anloague

We conducted a study to compare 3 methods of measuring knee range of motion: visual estimation by physicians, hand goniometry by physical therapists, and radiographic goniometry. We hypothesized that reliability would be high within and across all techniques. We found intrarater and interrater reliability to be satisfactory for visual estimation, hand goniometry, and radiographic goniometry. Interrater reliability across methods did not agree satisfactorily. Between-methods differences in estimating knee range of motion may result from variations in technique among physicians and physical therapists.

Scoliosis Analog Model For The Evaluation Of Bracing Technology, Chloe Ly Chung Dec 2015

Scoliosis Analog Model For The Evaluation Of Bracing Technology, Chloe Ly Chung

Theses and Dissertations (ETD)

Thoracolumbar braces are commonly used to treat Adolescent Idiopathic Scoliosis (AIS). Braces serve to reduce and prevent progression of the spinal curve by applying corrective forces. The magnitude and direction of these corrective forces applied by the brace to the spine remain unknown. Additionally the brace fitting process involves making alterations to the brace that affect its corrective force capacity. The objective was to design and validate an analog model of a mid-thoracic single curve scoliotic deformity for quantifying structural properties of the brace and the force response of the brace on the spine. This model was used to investigate …

A New Method For Shear Wave Speed Estimation In Shear Wave Elastography, Aaron J. Engel, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Visualization of mechanical properties of tissue can aid in noninvasive pathology diagnosis. Shear wave elastography (SWE) measures the elastic properties of soft tissues by estimation of local shear wave propagation speed. In this paper, a new robust method for estimation of shear wave speed is introduced which has the potential for simplifying continuous filtering and real-time elasticity processing. Shear waves were generated by external mechanical excitation and imaged at a high frame rate. Three homogeneous phantoms of varying elastic moduli and one inclusion phantom were imaged. Waves propagating in separate directions were filtered and shear wave speed was estimated by …

Feasibility Of Using Raman-Based Techniques For Breast Cancer Detection, Sara Mollamohammada

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Breast cancer is one of the common types of cancer among women all over the world. Early diagnosis is an effective way that improve the treatment process and gives the patients a better chance of survival. Many of the patients infected by breast cancer choose breast conservation surgery (BCS). However, some of those will be subjected to mastectomy, and many will have tumor recurrence as there is no precise technique to show the tumor margins. Raman-based methods are powerful techniques with potential to rapidly differentiate normal from tumor tissues and provides a solution to detect tumor margin. This is because …

Breast Cancer Rehabilitation: Clinical Examination And Outcomes Assessment, Nicole L. Stout, Shana Harrington, Lucinda Pfalzer, Mary Insana Fisher

Mary Insana Fisher

Breast cancer is the most commonly diagnosed cancer in women in the United States. The treatment for breast cancer occurs along a protracted time period and includes many different disease treatment modalities. These treatments carry with them a large number of adverse effects that negatively impact function in both the short term and long term. It is necessary for rehabilitation providers to interface with patients being treated for breast cancer throughout the continuum of care so that interval assessments can be conducted to identify emerging impairments and alleviate disability. To achieve this, the rehabilitation provider must have an understanding of …

Echocardiographic Predictors Of Admission Among Patients With Heart Failure With Reduced Ejection Fraction, Chi C. Cho, Yang Shi, Robyn Shearer, Nasir Z. Sulemanjee, Dianne L. Zwicke, T. Edward Hastings, Omar M. Cheema, Vinay Thohan

Journal of Patient-Centered Research and Reviews

Background: Congestive heart failure afflicts 5.7 million people in the United States with annual incidence of 600,000 and mortality of 280,000. Heart failure accounts for greater than 1 million hospitalizations annually and the single largest inpatient Medicare expense. As the U.S. population ages and greater emphasis is placed on population health as a means to bend projected health care expenditures, large health care organizations will need to develop algorithms to identify patients at high risk with heart failure and possibly preempt hospitalizations. Doppler echocardiography is routinely performed in clinical assessment of severe heart failure.

Purpose: We sought to determine echocardiographic …

Cardiopulmonary Exercise Testing-Based Algorithm And Its Usefulness In Clinical Cardiology, Mirza Nubair Ahmad, Syed Hasan Yusuf, Rafath Ullah, Mary Ellis, Haroon Yousaf, Timothy E. Paterick, Khawaja Afzal Ammar

Journal of Patient-Centered Research and Reviews

Background: Only cardiopulmonary exercise (CPX) testing provides information on the ability of the cardiovascular system to meet the body’s metabolic demands in terms of oxygen consumption (VO2) and carbon dioxide production (VCO2). However, CPX testing is underutilized by cardiologists due to complex diagnostic algorithms involving up to 30 variables as well as lack of validation studies. In addition, CPX also provides oxygen (O2) pulse as a continuous measure of stroke volume, which is its superiority to other stress modalities in which systolic function is measured at peak stress and rest. In the literature, it …

Real-World Relevance Of Manual Electrocardiography Qt Interval Measurement, Satish Velagapudi, Zahra Nur Khaled, Bilal Omery, Firas Zahwe, Michael Anigbogu, Sarah Zukkoor, Indrajit Choudhuri

Journal of Patient-Centered Research and Reviews

Background: Electrocardiography (ECG) QT interval (QTI) prolongation independently predicts sudden death. Hospitalized patients are commonly exposed to multiple QT-prolonging drugs, and manual measurement of ECG QTI based on identifying the intersection of isoelectricity with the tangent to the terminal phase T-wave slope (QTTTT) is advocated due to inaccuracies in automated detection algorithms that may imprecisely identify QT duration.

Purpose: We evaluated the performance of QTTTT compared to a standard automated (12SL, GE Healthcare) method (QT-12SL).

Methods: Consecutively obtained ECGs of 250 hospitalized patients were reviewed. The QTI in leads II, aVR, V5 and V6 determined by QT-12SL and QTTTT were …

Partial Covariance Based Functional Connectivity Computation Using Ledoit-Wolf Covariance Regularization, Matthew R. Brier, Anish Mitra, John E. Mccarthy, Beau M. Ances, Abraham Z. Snyder

Mathematics Faculty Publications

Highlights •We use the well characterized matrix regularization technique described by Ledoit and Wolf to calculate high dimensional partial correlations in fMRI data. •Using this approach we demonstrate that partial correlations reveal RSN structure suggesting that RSNs are defined by widely and uniquely shared variance. •Partial correlation functional connectivity is sensitive to changes in brain state indicating that they contain functional information. Functional connectivity refers to shared signals among brain regions and is typically assessed in a task free state. Functional connectivity commonly is quantified between signal pairs using Pearson correlation. However, resting-state fMRI is a multivariate process exhibiting a …


Feasibility Of Using Arterial Spin Labeling For Detecting Longitudinal Changes In Cerebral Blood Flow, Tracy Ssali Oct 2015

Feasibility Of Using Arterial Spin Labeling For Detecting Longitudinal Changes In Cerebral Blood Flow, Tracy Ssali

Electronic Thesis and Dissertation Repository

The ability of the perfusion MRI technique, arterial spin labeling (ASL), to quantify cerebral blood flow (CBF) makes it attractive for longitudinal studies of changes in brain function, such as those related to chronic pain. However, ASL's poor spatial resolution makes image alignment between sessions difficult, leading to increased variance and greater Type-I errors. In addition, variability due to differences in basal blood flow between sessions and confounding effects such as the arterial transit time (ATT) have the potential to reduce reproducibility over time. The focus of this thesis is to investigate the ability of ASL to detect long-term changes …
