Clinical Diagnosis Support With Convolutional Neural Network By Transfer Learning, Spencer Fogleman, Jeremy Otsap, Sangrae Cho

SMU Data Science Review

Breast cancer is prevalent among women in the United States. Breast cancer screening is standard but requires a radiologist to review screening images to make a diagnosis. Diagnosis through the traditional screening method of mammography currently has an accuracy of about 78% for women of all ages and demographics. A more recent and precise technique called Digital Breast Tomosynthesis (DBT) has shown to be more promising but is less well studied. A machine learning model trained on DBT images has the potential to increase the success of identifying breast cancer and reduce the time it takes to diagnose a patient, …

Coffee, Tea, And Mammographic Breast Density In Premenopausal Women, Adashi Margaret Odama, Valerie Otti, Shuai Xu, Olamide Adebayo, Adetunji T Toriola

2020-Current year OA Pubs

Studies have investigated the associations of coffee and tea with mammographic breast density (MBD) in premenopausal women with inconsistent results. We analyzed data from 375 premenopausal women who attended a screening mammogram at Washington University School of Medicine, St. Louis, MO in 2016, and stratified the analyses by race (non-Hispanic White (NHW) vs. Black/African American). Participants self-reported the number of servings of coffee, caffeinated tea, and decaffeinated tea they consumed. Volpara software was used to determine volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV). We used generalized linear regression models to quantify the associations of coffee and …

Detection Of Breast Cancer In African American Women Using Walk-In Mammography, Munachi Nwosu

Dissertations

Abstract

Problem: Breast cancer is a life-threatening condition, in which the prognosis could potentially worsen with a delay in the detection and commencement of treatment. Scheduling patients for mammograms continues to allow for long wait times that exist in screening mammography. Lower rates of participation in scheduled screening mammograms contributes to the increased rate of advanced breast cancer diagnosis that exit in African American women and threatens their health outcomes. The purpose of this project was to implement walk-in mammography to increase participation for early breast cancer detection.

Methods: An observational descriptive design with a retrospective chart review. A PDSA …

Improving Mammography Rates Among The Hispanic Population: An Evidence-Based Project Utilizing A Promotora Intervention, Dawn Mirowski

Student Scholarly Projects

Practice Problem: Breast cancer is the leading cause of death in Hispanic women in the U.S., with mammography being the most effective means of reducing breast cancer mortality. Promotoras have been shown to improve health promotion, including mammography, among the Hispanic population.

PICOT: The PICOT question that guided this project was: In Hispanic women 40 years or older (P), how does the use of a promotora intervention (I), compared to no promotora intervention (C), affect mammography rates (O) within an 8-week period (T)?

Evidence: Twenty-one studies that met the inclusion criteria supported the use of promotoras to improve mammography …

Using The Multi-Theory Model (Mtm) Of Health Behavior Change To Explain The Correlates Of Mammography Screening Among Asian American Women, Manoj Sharma, Chia-Liang Dai, Kavita Batra, Ching-Chen Chen, Jennifer R. Pharr, Courtney Coughenour, Asma Awan, Hannah Catalano

Environmental & Occupational Health Faculty Publications

Globally, breast cancer is the most common malignancy affecting women. The incidence of breast cancer has been growing among Asian American women. Mammography is a screening procedure that provides early diagnosis for the timely treatment to reduce premature mortality due to breast cancer. However, there are no national data available that summarize the rates of mammography screening among Asian American women. Some small-scale studies have reported low rates of mammography uptake among Asian American women. This cross-sectional study utilized the fourth-generation, multi-theory model (MTM) of health behavior change to explain the correlates of mammography screening among Asian American women between …

In-Laboratory Breast Specimen Radiography Reduces Tissue Block Utilization And Improves Turnaround Time Of Pathologic Examination, Sri Krishna Chaitanya Arudra, Laura C Garvey, Ian S Hagemann

2020-Current year OA Pubs

BACKGROUND: This study was performed to determine whether in-laboratory specimen radiography reduces turnaround time or block utilization in surgical pathology.

METHODS: Specimens processed during a 48-day trial of an in-lab cabinet radiography device (Faxitron) were compared to a control group of specimens imaged in the mammography suite during a prior 1-year period, and to a second group of specimens not undergoing imaging of any type.

RESULTS: Cases imaged in the mammography suite had longer turnaround time than cases not requiring imaging (by 1.15 days for core biopsies, and 1.73 days for mastectomies; p < 0.0001). In contrast, cases imaged in-lab had turnaround time that was no longer than unimaged cases (p > 0.05 for core biopsies, lumpectomies and mastectomies). …

Diagnosis Of Triple Negative Breast Cancer (Tnbc) Using Mammography, Sarah Mihalka

Medical Imaging Senior Posters

Triple-Negative Breast Cancer (TNBC) is a malignant, aggressive cancer that can affect men or women. Mammography is very helpful in diagnosing this type of cancer. The only option at this time for treatment for TNBC is cytotoxic chemotherapy. There is research being conducted to obtain more treatment options for patients. This is proving to be difficult because TNBC is negative for all hormone receptors. On a mammogram, this cancer may present as a lobulated mass with or without calcifications. This comes as a surprise because most masses present on a mammogram tend to be spiculated. This proves for an …

Diagnostic Imaging Of Inflammatory Carcinoma Of The Breast With Mammography And Sonography, Aubrey Bullock

Student Research Poster Presentations 2021

Inflammatory Breast Carcinoma (IBC) is a rare type of breast cancer with a high incidence of metastases that makes the breast tender, red, swollen, and sometimes exhibits an orange peel appearance. These type of cancer cells block lymph vessels in the skin of the breast and develops rapidly. Risks factors include sex, lifestyle, age, reproductive factors, race, obesity, and family history. Breast cancer is the second leading cause of cancer deaths among women. Approximately 1 in 8 women have a risk of developing breast cancer. The most accurate way to diagnose inflammatory breast carcinoma is via mammography and/or sonography. Mammography/and …

Comparing 2d Vs 3d Mammography In Breast Imaging, Kelsey Little

Student Research Poster Presentations 2021

This project offers a comparison of 2D digital mammography (DM) and 3D digital breast tomosynthesis (DBT) to determine if one is more superior than the other in breast imaging. Types of mammography exams, different projections, breast cancer, equipment definitions, advantages, and disadvantages are also discussed. Breast cancer is one of the most common and most treatable types of cancer detected in women. Equipment is frequently evolving to better improve image quality and patient comfort. DM takes a stationary image of the compressed breast at one angle while DBT takes images in slices at multiple angles. This allows for better visualization …

Medical Papers and Journal Articles

Background: In the last decade, there has been an unprecedented amount of advocacy and attention surrounding the issue of breast density (BD) in relation to mammography screening. It is largely unknown what impact notifying women of their BD has had on clinical practice for PCPs. This systematic review aimed to synthesize evidence from existing studies to understand the impact of BD notification on primary care practitioners' (PCPs) knowledge, attitudes, and practice implications.

Methods: Empirical studies were identified through relevant database searches (database inception to May 2020). Two authors evaluated the eligibility of studies, extracted and crosschecked data, and assessed the …

The Impact Of Mandatory Mammographic Breast Density Notification On Supplemental Screening Practice In The United States: A Systematic Review, Shuangqin Huang, Nehmat Houssami, Meagan Brennan, Brooke Nickel

Medical Papers and Journal Articles

Purpose: Dense breast tissue is an independent risk factor for breast cancer and lowers the sensitivity of screening mammography. Supplemental screening with ultrasound or MRI improves breast cancer detection rate but has potential harms. Breast density notifcation (BDN) legislation has been introduced in the United States (US) and its impact on supplemental screening practice is unclear. This study systematically reviewed current evidence to explore the impact of BDN on supplemental screening practice in the US.

Methods: Medline, PubMed, Embase, Cochrane and the Cinhal Library databases were searched (2009-August 2020). Studies were assessed for eligibility, data were extracted and …
