“…Thus, according to the data of Ref. [23], the sensitivity and specificity of the melanoma diagnostics based on the measurement of the AF intensity under the UV laser excitation reached 77.8% and 93.3%, respectively. Thus, the efficiency of the proposed method is comparable with that of the method of the melanoma AF analysis in the visible spectral range.…”

“…Four of the six studied nevi were classified as melanoma basing on the proposed criteria, which is caused by the fact that both melanomas and nevi contain a large amount melanin fluorescing in the spectral region of interest. Apparently, this problem may be solved by operating in the visible or UV range [22,23]. However, one cannot increase the accuracy of the melanoma diagnostics.…”

Abstract. We propose a method for the diagnostics of skin neoplasms, based on the analysis of the changes in the autofluorescence spectra in the near infrared range. The autofluorescence was excited by means of the laser radiation with the wavelength 785 nm for ex vivo and in vivo studies with subsequent exponential approximation of its spectrum. The quantitative and qualitative criteria for the neoplasm type differentiation by the change of the curvature and the rate of decrease of the approximating curve are found. It is shown that the proposed approach allows the diagnostics of malignant melanomas with the accuracy of 88.4% for ex vivo studies, and 86.2 % for in vivo ones.

“…And by means of image analysis, this kind of instrument was proved to diagnosis different kinds of skin lesions [17]. Hemoglobin and melanin in the skin absorb different fluorescent wavelengths, therefore malignant tumor could be confirmed [18]. The absorption spectrum between burned area and normal skin are different.…”

Dermatosis, a kind of common and frequent disease, is harmful to health and risk against the lives of human beings. The detection of dermatosis is of great significance, especially to the early diagnosis of skin disease. Nowadays, the studies of spectral imaging technology in the diagnosis of skin disease are attracting more and more attentions. In this paper, we firstly review some literary products related to dermatosis detection and then make a comparison among fluorescence spectrum method, filter wheel method, liquid crystal tunable filter (LCTF) method and mosaic multispectral imaging technology. Finally we propose that the smaller, lighter and more cost-effective equipment should be the trend.
