Optimizing automated sleep stage scoring of 5-s mini-epochs: a transfer learning study

Louise Frøstrup Follin, Julie Anja Engelhard Christensen, Janita Vevelstad, Hilde T Juvodden et autres

STUDY OBJECTIVES: Conventional sleep staging relies on 30-s epochs, potentially concealing transient sleep stage intrusion and reducing precision. Building on our previous study of mini-epochs, we investigated whether U-Sleep, an existing automatic deep learning-based sleep staging model with high performance in epochs, …

Membrane curvature association of amphipathic helix 8 drives constitutive endocytosis of GPCRs

Jan Hendrik Schmidt, Rasmus Herlo, Joscha Rombach, Andreas Haahr Larsen et autres

Cellular signaling relies on the activity of transmembrane receptors and their presentation on the cellular surface. Their continuous insertion in the plasma membrane is balanced by constitutive and activity-dependent internalization, which is orchestrated by adaptor proteins recognizing semispecific motifs within the receptors' …

Artificial intelligence or sleep experts: comparing polysomnographic sleep staging in children and adolescents

Mathias Perslev, Cecilie Paulsrud, Steffen Ullitz Thorsen, Helle Leonthin et autres

STUDY OBJECTIVES: The manual annotation of polysomnography (PSG) hypnograms is difficult and time-consuming. U-Sleep is an alternative, fast, and publicly available, automated sleep staging system evaluated in adult PSGs. In this study, we compare the staging done by sleep experts and U-sleep …

Fully Automated Tumor Segmentation for Brain MRI data using Multiplanner UNet

Sumit Pandey, Satyasaran Changdar, Mathias Perslev, Erik B. Dam

Automated segmentation of distinct tumor regions is critical for accurate diagnosis and treatment planning in pediatric brain tumors. This study evaluates the efficacy of the Multi-Planner U-Net (MPUnet) approach in segmenting different tumor subregions across three challenging datasets: Pediatrics Tumor Challenge (PED), …

Local Gamma Augmentation for Ischemic Stroke Lesion Segmentation on MRI

Jon Middleton, Marko Bauer, Kaining Sheng, Mathias Perslev et autres

The identification and localisation of pathological tissues in medical images continues to command much attention among deep learning practitioners. When trained on abundant datasets, deep neural networks can match or exceed human performance. However, the scarcity of annotated data complicates the training …

Validation of the sleep EEG headband ZMax

Mahdad Jafarzadeh Esfahani, Frederik D. Weber, M. H. Boon, Simone Anthes et autres

Abstract Polysomnography (PSG) is the gold standard for recording sleep. However, the standard PSG systems are bulky, expensive, and often confined to lab environments. These systems are also time-consuming in electrode placement and sleep scoring. Such limitations render standard PSG systems less …

Towards automatic cartilage quantification in clinical trials – Continuing from the 2019 IWOAI knee segmentation challenge

Erik B. Dam, Arjun Desai, Cem M. Deniz, Haresh Rengaraj Rajamohan et autres

Objective: To evaluate whether the deep learning (DL) segmentation methods from the six teams that participated in the IWOAI 2019 Knee Cartilage Segmentation Challenge are appropriate for quantifying cartilage loss in longitudinal clinical trials. Design: We included 556 subjects from the Osteoarthritis …

Multi‐planar 3D knee MRI segmentation via UNet inspired architectures

Sandeep Singh Sengar, Christopher Meulengracht, Mikael Boesen, Henrik Gudbergsen et autres

Abstract The UNet has become the golden standard method for the segmentation of 2D medical images that any new method must be validated against. In recent years, a number of variations to the seminal UNet have been proposed with promising results in …
