Researchers have measured breast tissue in transmission and reflectance geometries by using continuous-wave spectroscopy, frequency-domain, or time-domain techniques [ 20, 21].
were computed from each mammogram and the absolute difference between both breasts was obtained to measure breast tissue asymmetry and was used to predict the likelihood of developing cancer [ 19].
As it is currently recommended that high-risk women also undergo annual MRI screening [ 2], there is an opportunity to use novel imaging approaches to measure breast tissue properties related to an individual woman's response to risk reduction interventions.
DOSI measures breast tissue physiological properties and composition (for example, tissue concentration of oxy- and deoxyhemoglobin, water and lipid).
Our cross-sectional study measured breast adipose tissue, breast buds, and testicular volume; observed breast and genital development; and collected vaginal wall cells and information on vaginal discharge.
The values we used for the microvessel density were measured in breast tissue so they are both physiologically realistic.
BORIS and CTCF mRNA levels were measured in breast tissue specimens and cell lines using the Platinum® Quantitative PCR Supermix (Invitrogen).
As they embarked on testing this clinical hypothesis, they discovered, much to their surprise, that existing technology for measuring estrogen in breast tissue was onerous and impractical, requiring patients to submit to biopsies under sedation and requiring the collection of a rather large amount of tissue.
The risk factors that were found on univariate analysis (adjusted for age) to be associated with percent density were in general also associated, in the same direction, with measures of breast tissue (see Li et al, 2005).
The laser fluence profiles were experimentally measured through chicken breast tissue and calibrated intralipid solution at various imaging depths.
