Radiomics: success stories, negative results, challenges ahead and hands-on sessions
Time
9:00 – 12:30.
Room
9B-0-913
Abstract
Almost fifteen years after the first papers coined the word “radiomics”, the first part of this tutorial will review the most notable achievements to date, FDA and CE approved products addressing image-based personalized medicine, clinical adoption, as well as notable negative results and areas where initial promises have not been fulfilled. We will then summarize best practices, study quality assessment and identify paradigms that are most appropriate for building successful radiomics models. We will then present our experience as the main organisers of the HEad and neCK TumOR segmentation and outcome prediction (HECKTOR) challenge for three consecutive years, our coordination efforts in the context of the second chapter of the Image Biomarker Standardisation Initiative (IBSI), our experience in the design and use of anthropomorphic phantoms to assess the reproducibility and harmonisation of radiomics. We will conclude this first part with perspectives in the context of approaches able to aggregate longitudinal patterns from multiple lesions for assessing prognosis and response to treatment. In the second part, we will organise hands-on sessions using our QuantImage v2 web platform, where participants will have the opportunity to develop, validate and interpret radiomics models, starting from pre-extracted features from a dataset of more than 100 patients. We will conclude the tutorial with a participatory discussion of the hands-on experience and general concluding remarks.

Abstract
This tutorial introduces modern performance and energy-aware video coding and content delivery solutions and tools, focusing on popular video streaming applications, i.e., VoD and live streaming. In this regard, after introducing fundamentals of modern video encoding and networking paradigms, we introduce modern solutions systems, using per-title encoding, per-scene encoding, virtualized and software networks, edge computing, overlay networks such as Content Delivery Networks (CDNs) and/or Peer-to-Peer (P2P) paradigms to provide latency and energy-efficient VoD and live HAS streaming. Furthermore, the tutorial also presents our tools, software, datasets, and testbeds to demonstrate our latest achievements and share practical insights for researchers, engineers, and students who want to improve conversational streaming or even test such techniques for immersive video sequences (e.g., tile-based 360-degree VR) with a focus on latency, economic cost, and energy.

Distributions Shifts, Generalizability and Reproducibility in Brain MRI Analysis
Time
13:30 – 17:00.
Room
9B-0-912
Abstract
The application of computer vision and deep learning to brain MRI analysis is hindered by key challenges: 1. Small Dataset Sizes and Data Scarcity: Brain imaging datasets are very small, often containing only hundreds or thousands of samples, compared to large natural image datasets. This data scarcity limits the training of accurate, generalizable models. Data sharing across studies is critical but remains limited due to privacy constraints and lack of standardization. 2. Data Bias and Distribution Shifts: MRI acquisition protocols vary significantly, leading to systematic biases and distribution shifts in the data. Models trained on one distribution fail to generalize well to others. 3. Lack of Reproducibility: Due to the challenges above and several image acquisition artefacts such as subject movement, hardware failures, technician experience, etc. This tutorial will cover cutting-edge techniques to address these challenges, including: – Efficient image quality control and artifact detection – Uncertainty quantification for model predictions – Causal reasoning to understand bias sources and debiasing techniques – Data augmentation using synthetic data and simulating distribution shifts – Quantitative MRI harmonization across scanners and protocols – Federated learning for collaborative model training while preserving privacy
