Digital breast tomosynthesis: a state-of-the-art review

Abstract

Digital Breast Tomosynthesis (DBT) is an X-ray mammography technique where multiple low-dose projection images of the breast are reconstructed in multiple tomographic images creating a semi-3D mammogram. This enables the visualization of a sequential set of thin sections of the breast, overcoming the masking effect of overlying fibroglandular breast tissue, then improving carcinoma detection and reducing false-positive cases. This review aims at describing current DBT technique, analyzing DBT in clinical practice and providing an overview of published studies on clinical experience with DBT in the screening and diagnostic settings.

Luminescent PtII Complexes of Tridentate Cyclometalating 2,5‐Bis(aryl)‐pyridine Ligands

“…The emission maxima and quantum yields in PMMA matrices (Table ) are only marginally sensitive to complex concentration (spectra shown in the Supporting Information), even though platinum(II) complexes can potentially interact through coplanar stacking. Consequently, the energy of the highest occupied molecular orbital (HOMO) is raised and the energy of the lowest unoccupied molecular orbital (LUMO) is reduced, resulting in a bathochromic shift of emission bands , . Instead, we do not observe such marked concentration‐dependent excimer formation and ascribe the slight redshifts to changes in the polarity of the environment.…”
