Joint webinars with EATRIS

In February and March this year, HYBRID organised joint webinars with EATRIS in their EATx series. The webinars covered the following topics: ‘Combining AI with clinical modalities’, ‘Advances in molecular imaging’, and ‘Imaging techniques and clinical applications’.

The webinars were presented by HYBRID fellows and PI’s. We hope you enjoy them!


Combining AI with clinical modalities

This webinar features 3 speakers:

Irène Buvat will briefly explain how AI can and actually already does enhance hybrid imaging and what to expect from AI in that domain in the coming years. Beyond the huge opportunities offered by AI, she will also mention the challenges to be overcome for AI to be a game changer in medical imaging, for the benefit of research and patients.

Nicolò Capobianco will present how artificial intelligence techniques, with their unprecedented ability to capture high-level patterns in natural data, can be used to obtain image-derived biomarkers in oncology rapidly and reproducibly.

Esteban Lucas Solari will talk about how simple machine learning tools can help predict cancer aggressiveness. He will also present a deep learning approach to automate cumbersome steps in the reading of prostate cancer images.

Advances in molecular imaging

This webinar features 4 speakers:

Bert Windhorst will provide an introduction on how EATRIS facilitates multi-site collaborations, showcasing a few examples from industry collaboration and infrastructure development.

Claude Comtat will talk about fully quantitative PET/MR imaging in oncology, based on the work of Florent Besson for lung tumours. Hybrid PET/MR systems will reveal their full clinical potential only if we revisit the acquisition paradigm toward fully quantitative multi-parametric imaging and do not replicate what is currently performed on separate PET/CT and MR systems. Admittedly, fully quantitative MR imaging requires more time than in usual clinical practice, but it also offers the opportunity to perform in parallel dynamic PET imaging for parametric PET imaging. This hybridity result in rich and dense information, requiring advanced processing tools to select relevant parameters for a given clinical question; machine learning techniques are ideally suited to address this challenge. The presentation will be illustrated with PET/MR data for lung tumour imaging.

Georg Schramm will talk about recent advances in the application of AI in molecular image reconstruction. Due to the outstanding performance of AI in the field of image processing (e.g. classification, segmentation), application of AI also emerged in the field of image reconstruction and restoration. This talk is a brief overview of recent research focusing on the use of AI in the process of image reconstruction in molecular imaging.

Guilherme Domingues Kolinger will talk about:

  • Spatial registration between brain PET and MRI when they are not acquired simultaneously (i.e. images not coming from a PET/MR scanner)
  • Voxel-wise brain image comparison: spatial normalisation of images into a common space
  • Use of pre-defined regions of interest (from an atlas) into the original brain PET image

Imaging techniques and clinical applications

This webinar featerus 3 speakers:

Vicky Goh will cover current practice; and discuss potential synergisms with integrated PET/MRI in disease detection and response assessment. The talk is entitled: “Assessing multiple myeloma: Potential synergisms with integrated PET/MRI”.

Stephan Nekolla will give a brief overview of multimodal applications in non-invasive cardiac imaging. While mono-modal imaging is clearly the dominating approach in cardiac imaging, synergistic use of integrated modalities offer advantages. However, the increased complexity is an important factor and needs to be carefully evaluated.

Malene Fischer will talk about how hybrid imaging can improve radiotherapy planning by improving our knowledge on tumour biology, decreasing uncertainties related to segmentation and pave the way for dose painting and adaptive treatment.
