Measurement of breast density with dual X-ray absorptiometry: feasibility

Radiology. 2002 May;223(2):554-7. doi: 10.1148/radiol.2232010482.


Dual x-ray absorptiometry (DXA) was used to quantify breast density with a phantom and with cadaveric breasts. With DXA, percentage of fat correlated with percentage of glandular density of the phantom (r > 0.998) and with density at mammography (r(adjusted) = 0.83). DXA precision (SD) was 0.5% without and 1.1% with breast repositioning. DXA devices can be used to accurately and precisely estimate breast tissue density.
