Measurements of breast density: no ratio for a ratio.
Breast density, as visible on mammograms, is generally assessed as the occupied percentage of the breast and is a risk factor for breast cancer. Various studies have looked into the causation and alteration of relative density but the relation of a determinant with a relative measure does not allow a direct etiologic interpretation. It was our goal to compare the effects of known determinants o...
متن کاملA prospective study of breast cancer risk using routine mammographic breast density measurements.
Mammographic breast density is a major risk factor for breast cancer but estimates of the relative risk associated with differing density patterns have varied widely. It is also unclear how menopausal status influences this association and to what extent the effects of density are due to its correlation with other risk factors. Most recent investigations of breast density have been case-control...
متن کاملLogistic discriminant analysis of breast cancer using ultrasound measurements
Background: Logistic discriminant method was applied to differentiate malignant from benign in a group of patients with proved breast lesions on the basis of ultrasonic parameters. Materials and Methods: Our database include 273 patients' ultrasonographic pictures consisting of 14 quantitative variables. The measured variables were ultrasound propagation velocity, acoustic impedence and attenua...
متن کاملViscosity and Density Measurements
2. Working Equations of the Vibrating-Wire Instrument Our implementation [1] of the steady-state vibrating-wire technique is similar to that described by Audonnet and Pádua [2] in which the wire is driven at frequency f by a constant sinusoidal current I, and the emf V(f) generated across the vibrating wire is measured with a two-phase lock-in amplifier. This measured emf generally comprises tw...
متن کاملObtaining Calibrated Marine Aerosol Extinction Measurements Using Horizontal Lidar Measurements, Differential Lidar-Target Measurements and A Polar Nephelometer
Lidars are ideal for mapping the spatial distribution of aerosol concentrations, however efforts to convert the lidar measurements into estimates of the aerosol extinction or scattering coefficient are usually complicated. The difficulties arise from the uncertainty in the aerosol backscatter-to-extinction ratio and the lidar calibration. In marine conditions with little absorption, the aerosol...
