Semi-Supervised Learning Allows for Improved Segmentation With Reduced Annotations of Brain Metastases Using Multicenter MRI Data.
J Magn Reson Imaging
January 2025
Department of Radiology, Ålesund Hospital, Møre og Romsdal Hospital Trust, Ålesund, Norway.
Background: Deep learning-based segmentation of brain metastases relies on large amounts of fully annotated data by domain experts. Semi-supervised learning offers potential efficient methods to improve model performance without excessive annotation burden.
Purpose: This work tests the viability of semi-supervision for brain metastases segmentation.

The dynamic susceptibility contrast (DSC) MRI measures of relative cerebral blood volume (rCBV) play a central role in monitoring therapeutic response and disease progression in patients with gliomas. Previous investigations have demonstrated promise of using rCBV in classifying tumor grade, elucidating tumor viability after therapy, and differentiating pseudoprogression and pseudoresponse. However, the quantification and reproducibility of rCBV measurements across patients, devices, and software remain a critical barrier to routine or clinical trial use of longitudinal DSC MRI in patients with gliomas.

The aim of this study was to explore parent-reported feeding difficulties in children with EA by applying Montreal Children's Hospital-Feeding Scale (MCH-FS), and to further explore associations between feeding difficulties and clinical factors, growth and nutritional intake.
Methods: Parents of EA children born between 2012 and 2017 were invited.

Background: There is limited research and conflicting results on the mental health and health-related quality of life of individuals surgically treated for hypospadias in childhood. Furthermore, the significance of patient-reported outcomes (PRO) in hypospadias is growing. More research is necessary on these topics, particularly in adolescents.
