To evaluate performance (image signal to noise ratio) of a digital mammographic system working in 2D planar versus tomosynthesis modality, a contrast detail phantom was developed embedding 1 cm plexyglas, including 49 holes of different diameter and depth, between two layers containing a breast simulating material. The acquisition protocol included 15 low dose projections (reconstructed 1mm-thi...

Abstract Breast screening with mammography is the most effective method of detecting early-stage breast cancer and reducing related mortality. Among intrinsic limits mammography, in terms clinical performance, overlapping normal pathological tissues one influential. Some new techniques as Digital Tomosynthesis (DBT) expected to overcome this limitation by providing a quasi-three-dimensional (3D...

Early investigations on the physical properties of digital mammography provided the impetus for further research [11-15]. These studies suggested that the image noise characteristics of digital systems could be better than for screenfi lm mammography. Therefore, the highresolution advantage of screen fi lm might not be as important for detection of microcalcifi cations in the breast as it was o...

UNLABELLED The aim of this study is to assess the impact of multiparametric MR imaging to an exact determination of the extent of invasive ductal and lobular breast cancers in routine clinical practice.180 women aged 27-74 years (median 52.4 years) with newly diagnosed invasive ductal and lobular breast cancers confirmed by core-cut or vacuum-assisted biopsy were examined by all three imaging m...

Despite controversy regarding mammography's efficacy, it continues to be the most commonly used breast cancer-screening modality. With the development of digital mammography, some improved benefit has been shown in women with dense breast tissue. However, the density of breast tissue continues to limit the sensitivity of conventional mammography. We discuss the development of some derivative di...

The early detection & diagnosing of deceases increases the survival rate in women. Today, mammography is the most common and effective technique for the detection of breast cancer. Digital Telemammography is to help find smaller breast tumors; it must be simulated as radiologist presently works. may be the next tool in the fight against breast cancer. In this paper we demonstrate the different ...
