- Abstract
Purpose. Evaluation of wavelength-associated characteristics by transilluminating normal and pathological breast tissue. Method. 80 in vivo and 52 in vitro measurements were carried out with a Mamma-spectrograph (Siemens AG, ZFE München). 31 patients had a carcinoma and 59 patients a benign breast lesion. Measurements were performed with an increment of 10 nm, wavelengths between 550–1100 nm. Results. Normal and pathological breast tissue could be characterised in the area of absorption maxima of fat, water and haemoglobin. Atrophic breast tissue has a remarkable transmission minimum at 930 nm. Tumors with a high number of cells and neovascularisation showed a strong absorption over the entire “diagnostic window” and a transmission minimum at 970 nm. Below 700 nm the high concentration of haemoglobin resulted in an increase of transmission. Less wavelength-associated characteristics were seen in tumors with mastopatically-transformed surrounding tissue. Conclusion. To differentiate breast tissue, transillumination has to be performed in the area of absorption maxima of fat, water and haemoglobin.
