Automated Estimation of Melanocytic Skin Tumor Thickness by Ultrasonic Radiofrequency Data

Abstract

The efficient automated tumor thickness measurement method developed could be used as a tool for preoperative assessment of melanocytic skin tumor thickness.

The significance of spectrophotometric image analysis for diagnosis of the melanocytic skin tumours in association with their thickness

“…High‐frequency ultrasonic examination usually is used for the thickness evaluation of skin tumours. Good agreement with histologically evaluated thicknesses was observed in most studies . In this study, all cases of histologically diagnosed melanomas in situ were estimated as MST with thicknesses 0.01‐1.00 mm by analysing ultrasound images.…”

“…[13][14][15][16] In our previous study we proposed to use analysis of raw ultrasonic signals for the evaluation of up to 1 mm thickness MST. 17 In this study, we hypothesized that the analysis of SIAgraphs can provide the information which correlate with MST penetration or thickness. So, the purpose of this study is to evaluate the diagnostic value of SIAscopic features for MST diagnosis at different thickness.…”

“…Good agreement with histologically evaluated thicknesses was observed in most studies. 12,16,17 In this study, all cases of histologically diagnosed melanomas in situ were estimated as MST with thicknesses 0.01-1.00 mm by analysing ultrasound images. This can be explained by the hypothesis that strong lymphocytic reaction is suspected in the early stage of malignancy.…”

“…Strong correlation has been observed between MST thicknesses evaluated, using high‐frequency US and histopathology . In our previous study we proposed to use analysis of raw ultrasonic signals for the evaluation of up to 1 mm thickness MST . However, ultrasonic examination has some limitations.…”

Verification of new method for automatic thickness measurement of melanocytic skin tumours by high frequency ultrasound

“…The review of Jasaitiene et al [7] and the recent studies [3,5,8,[9][10][11][12][13][14][15][16] showed a good correlation between pT and manually (mT) measured US thickness of MST using a 20-100 MHz transducer (Table 1). An overestimation of mT resulting from the impossibility of differentiating lymphocytic infiltrate or underlying melanocytic nevus cells from CM tissue has been reported in most studies [3,5,[9][10][11].…”
