    1. Non-invasive scoring of cellular atypia in keratinocyte cancers in 3D LC-OCT images using Deep Learning

      Non-invasive scoring of cellular atypia in keratinocyte cancers in 3D LC-OCT images using Deep Learning

      Diagnosis based on histopathology for skin cancer detection is today's gold standard and relies on the presence or absence of biomarkers and cellular atypia. However it suffers drawbacks: it requires a strong expertise and is time-consuming. Moreover the notion of atypia or dysplasia of the visible cells used for diagnosis is very subjective, with poor inter-rater agreement reported in the literature. Lastly, histology requires a biopsy which is an invasive procedure and only captures a small sample of the lesion, which is insufficient in the context of large fields of cancerization. Here we demonstrate that the notion of cellular ...

    2. Line-field confocal optical coherence tomography as a tool for three-dimensional in vivo quantification of healthy epidermis: a pilot study

      Line-field confocal optical coherence tomography as a tool for three-dimensional in vivo quantification of healthy epidermis: a pilot study

      Epidermal three-dimensional (3D) topography/quantification have not been completely characterized yet. The recently developed line-field confocal optical coherence tomography (LC-OCT) provides real-time, high-resolution, in-vivo 3D imaging of the skin. This pilot study aimed at quantifying epidermal metrics [epidermal thicknesses, dermal-epidermal junction (DEJ) undulation and keratinocyte number/shape/size] using 3D LC-OCT. For each study participant (8 female, skin-type-II, younger/older volunteers), seven body sites were imaged with LC-OCT. Epidermal metrics were calculated by segmentations and measurements assisted by artificial intelligence (AI) when appropriate. Thicknesses of epidermis/SC, DEJ undulation and keratinocyte nuclei volume varied across body sites. Evidence of keratinocyte ...

    3. Line-field confocal optical coherence tomography of actinic keratosis: a case series

      Line-field confocal optical coherence tomography of actinic keratosis: a case series

      Line-field confocal optical coherence tomography (LC-OCT) is a non-invasive imaging technique that was recently developed, combining high penetration depth (up to 500-µm, approaching that of conventional OCT) with high isotropic resolution [lateral: 1.3 µm; axial: 1.1 µm - similar to that of reflectance confocal microscopy (RCM)]. 1 .

    4. Line-field confocal optical coherence tomography of sebaceous hyperplasia: a case series

      Line-field confocal optical coherence tomography of sebaceous hyperplasia: a case series

      Line-field confocal optical coherence tomography (LC-OCT) is a newly developed non-invasive imaging technique that combines high penetration depth (500 µm, similar to conventional OCT) with high isotropic resolution (lateral 1.3 µm, axial 1.1 µm, similar to reflectance confocal microscopy [RCM]). 1 Moreover, with its ability to produce images in both vertical and horizontal planes, it enables a tridimensional (3D) analysis of the skin, which can prove very useful for assessing physiological 2 as well as pathological skin.

    5. Methods of Melanoma Detection

      Methods of Melanoma Detection

      Detection and removal of melanoma, before it has metastasized, dramatically improves prognosis and survival. The purpose of this chapter is to (1) summarize current methods of melanoma detection and (2) review state-of-the-art detection methods and technologies that have the potential to reduce melanoma mortality. Current strategies for the detection of melanoma range from population-based educational campaigns and screening to the use of algorithm-driven imaging technologies and performance of assays that identify markers of transformation. This chapter will begin by describing state-of-the-art methods for educating and increasing awareness of at-risk individuals and for performing comprehensive screening examinations. Standard and advanced photographic ...
