Item type:Publication, New Dermoscopy Pattern in Nevus‐Associated Melanomas(Wiley, 2025-04-19) ;Nelson Lobos‐Guede ;Dan Hartmann ;Valentina Darlic ;Cristina CarreraLlucia AlosMelanomas can appear de novo or in association with a pre‐existing nevus. The association of melanomas with pre‐existing nevi and its role as a melanoma precursor is a controversial issue. Dermoscopy can increase melanoma's diagnostic accuracy and help us suspect nevus‐associated melanomas (NAM). Differentiating NAMs clinically and dermoscopically can be challenging. There are few published studies so far describing dermoscopic features of NAM that have differentiated from <jats:italic>de novo</jats:italic> melanomas, such as multi‐component pattern, multifocal pigmentation, atypical pigment network, regression structures, negative pigment network, irregular globules, and streaks. Here, we report four acquired compound NAMs showing a starburst pattern (SP) within the lesion. No publications have reported NAMs with melanoma components in the form of SP arising within the center of the lesion. Therefore, when faced with a compound or intradermal nevus with incipient central reticulated pigmentation, especially if there is no history of trauma or previous surgery, we must pay alert to the possibility of an early development of melanoma.2 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Interpretable multimodal classification for age-related macular degeneration diagnosis(2024) ;Carla Vairetti ;Sebastián Maldonado ;Loreto Cuitino; Xu Yanwu<jats:p>Explainable Artificial Intelligence (XAI) is an emerging machine learning field that has been successful in medical image analysis. Interpretable approaches are able to “unbox” the black-box decisions made by AI systems, aiding medical doctors to justify their diagnostics better. In this paper, we analyze the performance of three different XAI strategies for medical image analysis in ophthalmology. We consider a multimodal deep learning model that combines optical coherence tomography (OCT) and infrared reflectance (IR) imaging for the diagnosis of age-related macular degeneration (AMD). The classification model is able to achieve an accuracy of 0.94, performing better than other unimodal alternatives. We analyze the XAI methods in terms of their ability to identify retinal damage and ease of interpretation, concluding that grad-CAM and guided grad-CAM can be combined to have both a coarse visual justification and a fine-grained analysis of the retinal layers. We provide important insights and recommendations for practitioners on how to design automated and explainable screening tests based on the combination of two image sources.</jats:p>Scopus© Citations 1 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, The BrainLat project, a multimodal neuroimaging dataset of neurodegeneration from underrepresented backgrounds(2023) ;Pavel Prado ;Vicente Medel ;Raul Gonzalez-Gomez ;Agustín Sainz-BallesterosVictor VidalThe Latin American Brain Health Institute (BrainLat) has released a unique multimodal neuroimaging dataset of 780 participants from Latin American. The dataset includes 530 patients with neurodegenerative diseases such as Alzheimer’s disease (AD), behavioral variant frontotemporal dementia (bvFTD), multiple sclerosis (MS), Parkinson’s disease (PD), and 250 healthy controls (HCs). This dataset (62.7 ± 9.5 years, age range 21–89 years) was collected through a multicentric effort across five Latin American countries to address the need for affordable, scalable, and available biomarkers in regions with larger inequities. The BrainLat is the first regional collection of clinical and cognitive assessments, anatomical magnetic resonance imaging (MRI), resting-state functional MRI (fMRI), diffusion-weighted MRI (DWI), and high density resting-state electroencephalography (EEG) in dementia patients. In addition, it includes demographic information about harmonized recruitment and assessment protocols. The dataset is publicly available to encourage further research and development of tools and health applications for neurodegeneration based on multimodal neuroimaging, promoting the assessment of regional variability and inclusion of underrepresented participants in research.30Scopus© Citations 22 - Some of the metrics are blocked by yourconsent settings
