Diffuse optical measurement of blood flow in breast tumors

Opt Lett. 2005 Nov 1;30(21):2915-7. doi: 10.1364/ol.30.002915.

Abstract

Blood flow contrast between tumor and normal tissues in patients with malignant and benign breast cancer was measured by diffuse optical correlation methods. The measurements were carried out with a hand-held optical probe that was manually scanned over the tumor-bearing breast. Increased blood flow was observed in tumor regions relative to healthy tissue, and control subjects did not exhibit significant blood flow heterogeneity. The measurements introduce a new optical contrast for diffuse optical mammography.
