BACKGROUND Mammography is the primary imaging technique for detection and diagnosis of breast cancer; however, the contrast of a mammogram image is often poor, especially for dense and glandular tissues. In these cases the radiologist may miss some diagnostically important microcalcifications. In order to improve diagnosis of cancer correctly, image enhancement technology is often used to enhan...

Desmoid tumor of the breast is a rare benign entity that usually is mistaken for carcinoma clinically and radiologically. We report two cases of desmoid tumor of the breast detected by mammography screening using digital breast tomosynthesis (DBT). The larger tumor was detected at both full-field digital mammography (FFDM) and DBT. The smaller desmoid tumor, however, was identified only at tomo...

8 The advantages of digital radiography (DR) over screen-fi lm (SF) techniques in medical X-ray imaging are well documented in the literature and unanimously acknowledged by radiologists as well as physicists. For the past decade manufacturers have developed a number of commercial digital X-ray imaging systems covering the full range of radiographic applications. The tight requirements in terms...

Purpose To compare the clinical performance of synthesized two-dimensional (s2D) mammography combined with digital breast tomosynthesis (DBT) with that of full-field digital mammography (FFDM) alone and FFDM combined with DBT in a large community-based screening population by analyzing recall rate, positive predictive value, and cancer detection rate. Materials and Methods This was a retrospect...

Digital breast tomosynthesis (DBT) is an emerging technique that allows for slices parallel with the detector to be constructed through the breast, as opposed to two dimensional mammography. Present phantoms for use on mammography systems are two dimensional in nature and focus mainly on differences in contrast. Since tomosynthesis is a three-dimensional-technique, a suitable phantom for use on...

The presence of clustered microcalcifications is one of the earliest signs in breast cancer detection. Although there exist many studies broaching this problem, most of them are nonreproducible due to the use of proprietary image datasets. We use a known subset of the currently largest publicly available mammography database, the Digital Database for Screening Mammography (DDSM), to develop a c...

This procedure has as an objective establishing the main reasons to mammography rejection. The rejection analysis is an important tool from the quality control programs, which contributes to the evaluation of the image ́s quality standard. The analysis methodology is based on the recommendations from Honea et al.. For a two months period, the rejected examinations in the technician ́s workstation...

This paper discusses the most important aspects and problems related to the management of breast cancer imaging, at a center specialized in breast pathology. We review the established and emerging diagnostic techniques, their indications, and peculiarities: digital mammography, CAD systems, and the recent digital breast tomosynthesis, ultrasound and complementary elastography, molecular imaging...

To correlate breast density quantified from digital mammograms with mean and maximum standardized uptake values (SUVs) from positron emission tomography (PET). This was a prospective study that included 56 women with a history of suspicion of breast cancer (mean age 49.2 +/- 9.3 years), who underwent 18F-fluoro-2-deoxyglucose (FDG)-PET imaging of their breasts as well as digital mammography. A ...
