Abstract Background Breast cancer is one of the leading causes female morbidity and mortality. Management options vary between lesions BIRADS categories 3 4. Therefore, reliable differentiation would improve outcome. Although sonomammography contrast-enhanced breast magnetic resonance imaging (CE-MRI) remain cornerstone for assessment disease, additional, non-invasive techniques can be used to ...

Purpose of the study . Was to assess prospects for use vacuum aspiration biopsy in terms breast cancer diagnosis patients with focal changes categorised by 3 and 4a according BIRADS scale. Materials methods In period from February 2020 July 2021, 41 ( n = 41) patient nodules categories has been passed biopsies (VAB) under local infiltration anesthesia ultrasound navigation. The 17 % 7) nodular ...

In this paper, a hybrid segmentation method for detection of masses in digitized mammograms has been developed using three parallel approaches: adaptive thresholding method, Gabor filtering and fuzzy entropy feature as a CAD scheme. The algorithm consists of the following steps: a) Preprocessing of the digitized mammograms including identification of region of interest (ROI) as candidate for ma...

BACKGROUND Breast cancer is the commonest female cancer in Nigeria. Despite its increased awareness, affordability of available screening tools is a bane. Mammography, the goal standard for screening is costly and not widely available in terms of infrastructure, technical/personnel capabilities. Ultrasound is accessible and affordable. OBJECTIVES This study compared the use of ultrasound and ...

This paper presents a method for automated mammographic risk classification based on breast density estimation in mammograms. The overall profile of breast tissue density is represented using a topographic map, which is a hierarchical representation, obtained from the upper level sets of an image. A shape tree is constructed to describe the topological and geometrical structure of the shapes (i...

In this paper, we present a new dimension reduction method using Wilk’s Lambda Average Threshold (WLAT) for classifying the masses present in mammogram. According to Breast Imaging Reporting and Data System (BIRADS) benign and malignant can be differentiated using its shape, size and density, which is how radiologist visualize the mammograms. Measuring regular and irregular shapes mathematicall...

Paget’s disease of the breast was first described by Sir James Paget in 1874. Although rare, it is often associated with underlying carcinoma in situ or invasive cancer. It accounts for 1-3 % of mammary tumors and less than 5% of breast cancers in humans. We report the case of a 50 year-old patient presenting with left erosive lesion of the nipple evolving over more than 1 year. Clinical examin...

OBJECTIVE To evaluate the inter- and intra-observer variability among radiologists in the characterisation of mammograms according to Breast Imaging Reporting and Data System assessment and breast density categories. METHODS The descriptive cross-sectional study was conducted at Aga Khan University Hospital, Karachi, from January 2014 to June 2014. Using non-probability purposive sampling, al...

BACKGROUND Prior single institution studies suggest MRI may improve the assessment of the extent of cancer within the breast, and thus reduce the risk of leaving macroscopic disease in the breast following breast conservation therapy. We report on the rate of MRI and mammography detection of foci of distinct incidental cancer in a prospective, multi center trial involving 426 women with confirm...
