Dual-energy contrast-enhanced mammography.
The degree of vascularization in breast lesions is related to their malignancy. For this reason, functional diagnostic imaging techniques have become important in recent years. Dual-energy contrast-enhanced mammography is a new, apparently promising technique in breast cancer that provides information about the degree of vascularization of the lesion in addition to the morphological information...
متن کاملSimulation and Phantom Studies of Contrast-Enhanced Dual Energy Mammography (CEDEM)
Contrast-enhanced dual energy mammography (CEDEM) has been shown effective in enhancing the visibility of breast cancer in diagnostic mammographic images. The simulation and phantom studies of CEDEM were implemented to enhance acquisition techniques of a dedicated cone-beam breast CT scanner fabricated in our laboratory. CEDEM images were computersimulated numerically, and the results were comp...
متن کاملEstimating breast thickness for dual-energy subtraction in contrast-enhanced digital mammography using calibration phantoms
Dual-energy contrast-enhanced digital mammography (DE CE-DM) uses an iodinated contrast agent to image the perfusion and vasculature of the breast. DE images are obtained by a weighted logarithmic subtraction of the high-energy (HE) and low-energy (LE) image pairs. We hypothesized that the optimal DE subtraction weighting factor is thicknessdependent, and developed a method for determining brea...
متن کاملEstimating Breast Thickness for Dual-Energy Subtraction in Contrast-Enhanced Digital Mammography: A Theoretical Model
Dual-energy contrast-enhanced digital mammography (DE CE-DM) images the perfusion and vasculature of the breast using an iodinated contrast agent. High-energy (HE) and low-energy (LE) images of the breast are acquired; the DE image is obtained by a weighted logarithmic subtraction of the image pair. We hypothesized that the optimal DE subtraction weighting factor, w, is dependent on three param...
متن کاملAn introduction to contrast enhanced spectral mammography
Contrast enhanced spectral mammography (CESM) is a new technology, gaining acceptance throughout Europe and the USA, but only recently introduced to the UK. GE Healthcare is currently the only UK vendor of CESM, using the brand name Senobright. In this article, we will explore the theory behind the technology and the practicalities of performing the test. A brief literature overview is provided...
