PURPOSE To examine "constant lesion sharpness" as a morphological diagnostic sign in the differential diagnosis between benign and malignant lesions. MATERIAL AND METHODS This prospective study had institutional review board approval and was HIPAA compliant. In total 1014 consecutive patients were examined (mean age 55 years ± 13 years) and evaluated in our University hospital towards the mor...
Abstract Background Proper assessment of mammographically detected asymmetries is essential to avoid unnecessary biopsies and missed cancers as they may be a benign or malignant cause. According ACR BIRADS atlas 2013, are classified into asymmetry, focal global developing asymmetry. We aimed assess the diagnostic performance artificial intelligence in compared breast ultrasound well combined ma...
Abstract Background Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has always been a problem solver in troublesome breast lesions. Despite its many advantages, the encountered low specificity results unnecessary biopsies. Diffusion-weighted MRI (DW-MRI) is well-established technique that helps characterizing lesions according to their water diffusivity. So this work aimed assess...
Background: Magnetic resonance imaging (MRI) mammography has been recommended as a problem solving tool in patients with breast lump for which newer protocols like abbreviated, ultrafast MRI and diffusion are now available. For interpretation lexicons BIRADS Kaiser score system available but there is scope improvement of results need lexicons.Methods: Retrospective study 175 who had was done. T...
The purpose of this study was to investigate factors that impact the generalization of breast cancer computer-aided diagnosis (CAD) systems that utilize the Breast Imaging Reporting and Data System (BI-RADS ). Data sets from four institutions were analyzed: Duke University Medical Center, University of Pennsylvania Medical Center, Massachusetts General Hospital, and Wake Forest University. The ...
BACKGROUND Percutaneous, vacuum-assisted, large-gauge core needle biopsy (VACNB) provides an alternative to open surgical biopsy as an initial diagnostic tool for breast lesions, yet rates of underestimating malignant diagnoses remain sufficiently high to warrant surgical biopsy in some cases. The current study was performed to determine if the Breast Lesion Excision System (BLES) provides a fe...
A blinded retrospective validation study was performed in a university-based hospital in northeastern China to determine whether the breast imaging reporting and data system (BIRADS) defines a group of patients with nonpalpable breast lesions (NPBLs) in whom finewire localization biopsy (FWLB) is appropriate. We reviewed 182 consecutive patients with NPBLs who underwent FWLB. The patients’ preo...
PURPOSE The aim of our study was to evaluate the risk of malignancy and to determine which clinical variables differentiate between benign and malignant focal breast lesions found incidentally on (18)F-flourodeoxyglucose positron emission tomography and computed tomography (FDG PET/CT). METHODS From March 2005 to October 2011, 21,224 women with no history of breast cancer underwent FDG PET/CT...
A Novel hybrid segmentation method has been developed for detection of masses in digitized mammograms using three parallel approaches: adaptive thresholding method, Gabor filtering and fuzzy entropy feature as a computer-aided detection(CAD) scheme. The algorithm consists of the following steps: a) Preprocessing of the digitized mammograms including identification of region of interest (ROI) as...
