Dermatological feasibility of multimodal facial color imaging modality for cross‐evaluation of facial actinic keratosis

Abstract

Background/Purpose Digital color image analysis is currently considered as a routine procedure in dermatology. In our previous study, a multimodal facial color imaging modality (MFCIM), which provides a conventional, parallel- and cross-polarization, and fluorescent color image, was introduced for objective evaluation of various facial skin lesions. This study introduces a commercial version of MFCIM, DermaVision-PRO, for routine clinical use in dermatology and demonstrates its dermatological feasibility for cross-evaluation of skin lesions. Methods/Results Sample images of subjects with actinic keratosis or non-melanoma skin cancers were obtained at four different imaging modes. Various image analysis methods were applied to cross-evaluate the skin lesion and, finally, extract valuable diagnostic information. DermaVision-PRO is potentially a useful tool as an objective macroscopic imaging modality for quick prescreening and cross-evaluation of facial skin lesions. Conclusion DermaVision-PRO may be utilized as a useful tool for cross-evaluation of widely distributed facial skin lesions and an efficient database management of patient information.

A Multicenter Pilot Evaluation of the National Institutes of Health Chronic Graft-versus-Host Disease (cGVHD) Therapeutic Response Measures: Feasibility, Interrater Reliability, and Minimum Detectable Change

“…If this finding is replicated in larger samples, clearer definitions to help distinguish between movable and nonmovable sclerosis should be considered to achieve greater reliability between raters. Future research to develop digitized, computer analyzed methods for estimating percent of BSA involved with specific cutaneous manifestations 18, 19 may also contribute to improvements in making such distinctions.…”

Effects of Jae-Seng Acupuncture Treatment on the Improvement of Nasolabial Folds and Eye Wrinkles

“…To relieve pain, the anesthetic cream was applied on the face for 30 min. DermaVision (OptoBioMed, Wonju, Korea) was used to analyze images of wrinkles, as reported previously [ 5 , 6 ]. For EW treatment, the needle was injected repeatedly to the dermis at a depth of 1-2 mm in the same direction as the wrinkles to stimulate the orbicularis oculi muscle, and the temporalis muscle was stimulated by injecting the needle in a parallel direction with the skin layer at a 2 cm depth.…”

Analysis of the number of enlarged pores according to site, age, and sex

“…2 We used the DermaVision™, which non‐invasively analyzes various lesions of the facial skin. The machine takes cross‐polarization, parallel polarization, and UV light images . It can simultaneously evaluate the number of enlarged pores, the amount of water, and the degree of wrinkles at the same time by selecting a certain area in the photographed image.…”
