Breast ultrasound is another technology employed in diagnosis and screening that can help differentiate between fluid filled and solid lesions, an important factor to determine if a lesion may be cancerous. [2] Breast MRI is a technology typically reserved for high-risk patients and patients recently diagnosed with breast cancer. [3]

Stratification for breast cancer risk on a mammogram is based on a reporting system known as Breast Imaging-Reporting and Data System , developed by the American College of Radiology in 1993. It has five general categories of findings: mass, asymmetry, architectural distortion, calcifications, and associated features.
Diffuse optical mammography, or simply optical mammography, is an emerging imaging technique that enables the investigation of the breast composition through spectral analysis. It combines in a single non-invasive tool the capability to implement breast cancer risk assessment, [ 2 ] lesion characterization, [ 3 ] therapy monitoring [ 4 ] and ...
Automated whole-breast ultrasound (AWBU) is a technique that produces volumetric images of the breast and is largely independent of operator skill. It utilizes high-frequency ultrasound to help perform a diagnostic evaluation of the lactiferous ducts ( duct sonography ) [ 5 ] and make dilated ducts and intraductal masses visible.
MRI breasts has the highest sensitivity to detect breast cancer when compared with other imaging modalities such as breast ultrasound or mammography. In the screening for breast cancer for high-risk women, sensitivity of MRI range from 83 to 94% while specificity (the confidence that a lesion is cancerous and not a false positive ) range from ...
Photon-counting breast tomosynthesis has been developed to a prototype state. [ 19 ] [ 20 ] [ 21 ] Tomosynthesis relies on a number of low-dose projections, which makes the influence of electronic noise higher than for conventional mammography, and photon-counting detectors with rejection of electronic noise are therefore beneficial with ...
The 808 nm laser beam can penetrate breast tissue of any density, and thus can work equally well in the examination and imaging of extremely dense and heterogeneous breast tissue. CTLM looks for the areas of high absorption, where there is a high hemoglobin concentration indicating rich network of blood vessels, or angiogenesis.
