PURPOSE: Vacuum Assisted Breast Biopsy (VABB) is a minimal invasive technique, in the diagnostic approach for non palpable lesions. The aim of this study was to evaluate the efficacy and accuracy of VABB in the investigation of breast microcalcifications, a significant mammographic sign of early breast cancer. The rate of histological underestimation and the false negative rate were assessed based on the follow up data and the histological examination of the surgical specimens. METHODS: From January 2005 to November 2011, 853 women with mammographically detected microcalcifications, classified as BI-RADS 3-5, were referred to our Breast Unit for evaluation...

Using a large set of ultrasound features does not necessarily ensure improved quantitative classification of breast tumors; rather, it often degrades the performance of a classifier. In this paper, we propose an effective feature reduction approach in the transform domain for improved multi-class classification of breast tumors. Feature transformation methods, such as empirical mode decomposition (EMD) and discrete wavelet transform (DWT), followed by a filter- or wrapper-based subset selection scheme are used to extract a set of non-redundant and more potential transform domain features through decorrelation of an optimally ordered sequence of N ultrasonic bi-modal (i...

Background The BI-RADS provides descriptors for microcalcifications based on morphology and distribution. However, the descriptor for category 4A microcalcifications is not specified in the 5th BI-RADS nor in the prior editions. Purpose To investigate how the category 4A assessment is applied to suspicious microcalcifications, and the appropriate descriptors for category 4A assessment for microcalcifications seen on mammography. Material and Methods From June 2008 to November 2011, 296 women with 305 suspicious microcalcifications that were assessed as BI-RADS category 4A, who underwent imaging-guided biopsy or surgery, were included...

OBJECTIVE: Ultrafast dynamic contrast-enhanced magnetic resonance imaging of the breast enables assessment of the contrast inflow dynamics while providing images with diagnostic spatial resolution. However, the slice thickness of common ultrafast techniques still prevents multiplanar reconstruction. In addition, some temporal blurring of the enhancement characteristics occurs in case view-sharing is used. We evaluate a prototype compressed-sensing volume-interpolated breath-hold examination (CS-VIBE) sequence for ultrafast breast MRI that improves through plane spatial resolution and avoids temporal blurring while maintaining an ultrafast temporal resolution (less than 5 seconds per volume)...

The Breast Imaging Reporting and Data System (BI-RADS) was developed to reduce variation in the descriptions of findings. Manual analysis of breast radiology report data is challenging but is necessary for clinical and healthcare quality assurance activities. The objective of this study is to develop a natural language processing (NLP) system for automated BI-RADS categories extraction from breast radiology reports. We evaluated an existing rule-based NLP algorithm, and then we developed and evaluated our own method using a supervised machine learning approach...

We tested, in the Province of Liege, an original approach that tends to individualize mass screening for breast cancer considering breast density and the notion of higher risk. We compared the previous recommendations (January to June 2012) in the age ranges of 40-49 years (n = 1.730) and 70-74 years (n = 286) to the new recommendations (June 2012 - December 2014) in the age ranges of 40-49 years (n = 11.123) and 70-74 years (n = 2.008). With the new recommendations, 38 % of women aged 40 to 49 years will benefit from a biennial invitation to screening due to a mainly greasy nature of their breasts (BI-RADS 1 and 2), while 11 % are classified BI-RADS 3 and 1 % BI-RADS 4 and are invited to perform an ultrasound to increase the screening sensitivity...
