This paper presents an algorithm which aims to assist the radiologist in identifying breast cancer at its earlier stages. It combines several image processing techniques like image negative, thresholding and segmentation techniques for detection of tumor in mammograms. The algorithm is verified by using mammograms from Mammographic Image Analysis Society. The results obtained by applying these ...

BACKGROUND Practice recommendations for mammography screening were issued by the U.S. Preventive Services Task Force in 2009 and expansion of insurance coverage was provided under the Patient Protection and Affordable Care Act soon thereafter, yet the influence of these changes on screening practices in the United States is not known. METHODS To determine changes in mammography screening and ...

OBJECTIVE This study evaluated the use of the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) by community radiologists by determining the concordance of assessment categories and recommendations assigned to screening mammograms. MATERIALS AND METHODS The study comprised the interpretations of 82,620 consecutive screening mammograms by 18 radiologists between ...

PURPOSE To evaluate the use of a computer-aided detection (CAD) system (designed for mammographic mass detection) to help improve mass interpretation and to compare CAD results with independent double-reading results. MATERIALS AND METHODS Screening mammograms from 500 cases were collected; 125 of these cases were screening-detected cancers, and 125 were interval cancers. Previously obtained ...

 ABSTRACTBackground: An electron beam generated X-ray spectrum consists of characteristic X-ray and continuous bermsstrahlung. The aim of this research is calculating and comparing X-ray spectra for different target filter of mammograms. Materials and Methods: Monte Carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the X-ray spectra. MC...

Abstract In a small number of people, an unexpected side effect the COVID-19 vaccine has emerged: swollen lymph nodes on same body as shot was given. For women who undergo breast screening soon after vaccination, such swelling can show up mammogram, so clinicians may need to take extra steps educate patients about this possibility and assess for follow-up testing.

This paper presents a novel approach to finding a priori interesting regions in mammograms. In order to delineate those regions of interest (ROI’s) in mammograms, which appear to be prominent, a topographic representation called the iso-level contour map consisting of iso-level contours at multiple intensity levels and region segmentation based-thresholding have been proposed. The simulation re...

Mammography is a specific type of imaging system used to examine the breast as mentioned by Tang et al (2009) and radiology information available online (2010). Wang and Karayiannis (1998) claim that, one of the difficulties with mammography is that mammograms generally have low contrast. This makes it difficult for the radiologists to interpret the results. CAD is used to aid radiologists in t...

Specific anatomical structures from the female body, such as axillary slope, armpit, pectoral muscle, or abdominal tissue, can be present in mammograms and might affect proper mammogram analysis, especially populations with overweight issues, is case Mexico. This work aims to determine if better results obtained an automatic analysis by removing fatty tissues a preprocessing step. The experimen...
