The purpose of this prospective study is to determine the diagnostic accuracy of near-infrared breast optical absorption imaging in patients with Breast Imaging Reporting and Data System (BIRADS) 4-5 non-palpable lesions scheduled for biopsy, using pathology after core or excisional biopsy as a reference. The patient's breast was positioned onto a panel of red light-emitting diodes (640 nm). A ...

The purpose of this study was to investigate the correlations between tumor-to-background ratio (TBR) obtained from breast-specific gamma imaging (BSGI) and the prognostic factors of breast cancer. Sixty-seven patients with invasive ductal carcinoma who underwent preoperative BSGI were enrolled. The BSGI images were visually scored from 1 to 5 according to a breast imaging reporting and data sy...

OBJECTIVE to analyze the epidemiological, clinical and mammographic profile of women with breast cancer who were treated at the mastology clinic of the University Hospital of Santa Maria and who underwent breast surgery between January 2007 and December 2012. METHODS this was a cross-sectional study, approved by the Ethics in Research Committee. A review of the patients' medical records was p...

Introduction Mammographic breast density is positively associated with risk of developing breast cancer for both preand postmenopausal women. Breast Imaging Reporting and Data System (BIRADS) or similar semiquantitative pattern analyses are inexpensive and suitable for large epidemiologic studies, but intrareader reliability in interpretation is suboptimal. Continuous, computerassisted measurem...

RATIONALE AND OBJECTIVES Improvements in the diagnosis of early breast cancers depend on a physician's ability to obtain the information necessary to distinguish nonpalpable malignant and benign tumors. Viscoelastic features that describe mechanical properties of tissues may help to distinguish these types of lesions. MATERIALS AND METHODS Twenty-one patients with nonpalpable, pathology-confi...

BACKGROUND Mammographic screening has become part of routine health care. We present a first analysis of screening mammography in a dedicated breast health centre in Africa. OBJECTIVE To establish a performance benchmark and provide data for health care policy and funding decisions on screening mammography. METHOD All mammography performed between January 2003 and August 2008 was entered in...

The aim of this study was to compare the imaging symptoms and microscopic findings in females with lobular neoplasia (LN) found on biopsy. 1,478 women who underwent primary open biopsy or surgical excision after percutaneous biopsy were reviewed. In 24 of them (1.6%), LN was found. In four patients, excisional biopsy with hook-wire localization was done primarily due to the radial scar. In 20 f...

OBJECTIVE The purpose of this study was to evaluate the sensitivity of breast-specific gamma imaging (BSGI) for the detection of breast cancer in dense versus nondense breasts. MATERIALS AND METHODS This was a retrospective study of 341 women with biopsy-proven breast cancer diagnosed from January 2004 to August 2009 who underwent BSGI before surgical excision. Patients with predominantly fat...
