Dual-energy contrast-enhanced spectral mammography (CESM)

Archives of Gynecology and Obstetrics, 2015
Dual-energy contrast-enhanced mammography is one of the latest developments in breast care. Imaging with contrast agents in breast cancer was already known from previous magnetic resonance imaging and computed tomography studies. However, high costs, limited availability-or high radiation dose-led to the development of contrast-enhanced spectral ...

The feasibility of contrast-enhanced spectral mammography immediately after contrast-enhanced CT

Radiological Physics and Technology, 2019
Contrast-enhanced spectral mammography (CESM) is a digital mammography method that requires an intravenous injection of iodinated contrast material to detect hypervascular lesions. In patients undergoing evaluation for metastases before breast tumor surgery, a contrast material must be injected for computed tomography (CT) and CESM studies. The purpose

Single-exposure contrast enhanced spectral mammography

Medical Imaging 2019: Physics of Medical Imaging, 2019
Contrast-enhanced spectral mammography (CESM) is being implemented to overcome the limitations of conventional mammography where tumor visualization is obstructed by overlapping glandular tissue. CESM exploits the spectral properties of a contrast agent by subtracting two images one obtained above and other below the K-edge energy.

Association between lesion enhancement and breast cancer in contrast-enhanced spectral mammography

Acta Radiologica, 2021
Background Contrast-enhanced spectral mammography (CESM) may help to determine the malignancy potential of lesions according to the degree of enhancement. Purpose To investigate the correlation between the degree of contrast ...

Contrast Enhanced Spectral Mammography (CESM)

The Bangkok Medical Journal, 2014
CESM is a technique to detect abnormal contrast enhancement by dynamic iodinated contrast medium study via intravenous injection using digital mammographic unit on the basis of subtraction of low and high energies. The dynamic images are displayed to evaluate the depletion. The breast cancer will depict the contrast.

Contrast Enhanced Spectral Mammography

Seminars in Ultrasound Ct and Mri, 2018
Contrast-enhanced spectral mammography (CESM) provides low-energy 2D mammographic images comparable to standard digital mammography and a post-contrast recombined image to assess tumor neovascularity similar to magnetic resonance imaging (MRI). The utilization of CESM in the United States is currently low but could increase rapidly given many potential

Computer-aided diagnosis of contrast-enhanced spectral mammography: A feasibility study

European Journal of Radiology, 2018
To evaluate whether the use of a computer-aided diagnosis-contrast-enhanced spectral mammography (CAD-CESM) tool can further increase the diagnostic performance of CESM compared with that of experienced radiologists.This IRB-approved retrospective study analyzed 50 lesions described on CESM from August 2014 to December 2015.

Contrast enhanced spectral mammography. Customer satisfaction.

2022
Purpose: The contrast enhanced spectral mammography is a natural evolution of the common mammography. This procedure can demonstrate the enhancement of a lesion not only by the increment of its density, but also recognizing the iodine as itself, thanks to a...

Challenges in contrast-enhanced spectral mammography interpretation: artefacts lexicon

Clinical Radiology, 2016
To review and describe commonly encountered artefacts in contrast-enhanced spectral mammography (CESM).This retrospective study included 200 women who underwent CESM examinations for screening and diagnostic purposes. Analysis was performed on the image data sets of these women, comprising of a total of 774 subtracted images.

Contrast enhanced spectral mammography: better than MRI?

European Journal of Radiology, 2012
The initial method developed for contrast enhanced mammography used temporal acquisitions of high-energy images before and after intravenous injection of iodinated contrast medium [1–4]. The patient had to be primarily positioned for breast compression, using minimal pressure not to alter diffusion of contrast agent.
