Material And Methods: A test set of 60 digital mammography cases, of which 20 were cancerous, were examined by 17 radiologists.

The implications of increased mammographic breast density for breast screening in Jordan.

Introduction: Mammographic breast density is associated with a four to six times increased risk for breast cancer. Mammographic breast density varies by ethnicity, geographical region and age. The aim of this study was to document for the first time the mammographic breast density of Jordanian women and to explore its relationship with age.

Mammographic Breast Density Profile of Jordanian Women With Normal and Breast Cancer Findings.

Purpose: To document the mammographic breast density (MBD) distribution of Jordanian women and the relationship with MBD with age. Correlation between breast cancer diagnosis and density was also explored.

Methods: A retrospective review of 660 screening mammograms from King Abdullah University Hospital was conducted.

Breast Cancer Diagnostic Efficacy in a Developing South-East Asian Country.

Background: Breast cancer, is increasing in prevalence amongst South East (SE) Asian women, highlighting the need for high quality, early diagnoses. This study investigated radiologists’ detection efficacy in a developing (DC) and developed (DDC) SE Asian country, as compared to Australian radiologists. Methods: Using a test-set of 60 mammographic cases, 20 containing cancer, JAFROC figures of merit (FOM) and ROC area under the curves (AUC) were calculated as well as location sensitivity, sensitivity and specificity.

A review of factors influencing radiologists' visual search behaviour.

This narrative literature review aims to identify the various factors that have significant impact on radiologists' visual search patterns. Identifying the factors that influences readers' visual search behaviour helps to understand their perception and interpretation of medical images, which in turn could lead to the development and implementation of effective strategies that could aid in improving the ability to detect abnormalities. Databases including PubMed, MedLine, Web of Science and ScienceDirect were searched using terms 'visual search', 'eye-tracking', 'radiology OR radiography', 'mammogram OR mammography' published since the early 1960s until June 30, 2016.

Imaging factors include sample-to-detector distance, X-ray energy, CT reconstruction method, phase retrieval algorithm applied to the CT projection images and maximum intensity projection.

X-Ray Phase-Contrast Technology in Breast Imaging: Principles, Options, and Clinical Application.

Objective: The purpose of this article is to review different x-ray phase-contrast breast imaging techniques and their potential application in clinical settings.

Conclusion: Phase-contrast imaging depicts not only the absorption contrast but also the refraction contrast of the transmitted x-ray beam. Early data suggest that this new modality may overcome some of the diagnostic limitations associated with current clinically available mammography systems and that it has potential for improving breast cancer detection.

Errors in Mammography Cannot be Solved Through Technology Alone.

Mammography has been the frontline screening tool for breast cancer for decades. However, high error rates in the form of false negatives (FNs) and false positives (FPs) have persisted despite technological improvements. Radiologists still miss between 10% and 30% of cancers while 80% of woman recalled for additional views have normal outcomes, with 40% of biopsied lesions being benign.

RELATIONSHIP BETWEEN RADIATION DOSE AND IMAGE QUALITY IN DIGITAL BREAST TOMOSYNTHESIS.

This phantom-based study aimed to examine radiation dose from digital breast tomosynthesis (DBT) and digital mammography (DM) and to assess the potential for dose reductions for each modality. Images were acquired at 10-60 mm thicknesses and four dose levels and mean glandular dose was determined using a solid-state dosemeter. Eleven readers assessed image quality and compared simulated lesions with those on a reference image, and the data produced was analysed with the Friedman and Wilcoxon signed-rank tests.
