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.
