Combining digital breast tomosynthesis and a laser-based
technique called diffuse optical tomography, radiologists may be
better able to distinguish malignant from benign lesions in the
breast, according to a
new study published in Radiology.
Diffuse optical tomography measures levels of hemoglobin
concentration, oxygen saturation, and other cellular
characteristics based on how light from a near-infrared laser is
absorbed and scattered within tissue.
