The purpose of this study is to provide a more accurate estimation of the radiation dose of contrast-enhanced spectral mammography (CESM) relative to that of 2D digital mammography and tomosynthesis using phantom and patient data and an accepted dosimetry protocol that eliminates vendor-specific average glandular dose (AGD) estimates while including breast density.

Contrast-enhanced spectral mammography (CESM) is a recently developed breast imaging technique. CESM relies on dual-energy acquisition following contrast agent injection to improve mammography sensiti...
The purpose of this study was to compare the diagnostic performance of contrast-enhanced spectral mammography (CESM) and ultrasound with that of standard digital mammography for breast cancer screenin...
The purpose of this article is to discuss the essential steps involved in performing, interpreting, managing, and reporting findings on contrast-enhanced mammography for successful implementation into...
The aim of this study was to evaluate the detection rate and diagnostic performance of 2-dimensional synthetic mammography (SM) as an adjunct to wide-angle digital breast tomosynthesis (WA-DBT) compar...
Accuracy of Calcium Scoring calculated from contrast-enhanced Coronary Computed Tomography Angiography using a dual-layer spectral CT: A comparison of Calcium Scoring from real and virtual non-contrast data.
Modern non-invasive evaluation of Coronary Artery Disease (CAD) requires non-contrast low dose Computed Tomography (CT) imaging for determination of Calcium Scoring (CACS) and contrast-enhanced imagin...
Women who attend for their screening mammogram will be recalled if an abnormality is detected on the screening mammogram. Calcifications account for 20% of the women recalled to second sta...
Introduction: To avoid unnecessary mastectomies and reoperations a correct size assessment of malignant lesions in breast is required. Sometimes a supplementary MRI is therefore recommende...
This is a feasibility study to evaluate dual-energy (DE) contrast-enhanced (CE) digital mammography to detect breast cancer in patients with increased breast density (BI-RADS category c or...
This research study is evaluating whether contrast enhanced mammography can be used as an alternative to breast Magnetic Resonance Imaging (MRI) for cancer screening
This research study is studying whether contrast enhanced mammography can predict if atypical ductal hyperplasia will progress to cancer. The device involved in this study is: -Con...
Substances used to allow enhanced visualization of tissues.
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector.
