Multimodal Data Fusion and Cross-Disciplinary Analytics in Medical Imaging

About this Research Topic

Background

Multimodal data fusion is transforming the landscape of medical imaging by integrating information from diverse imaging modalities—such as MRI, CT, PET, ultrasound, and spectral imaging—along with non-image data sources like biosignals and clinical records. This integrative approach enables more comprehensive, accurate, and actionable insights for diagnostic, prognostic, and therapeutic applications. However, challenges remain in harmonizing heterogeneous data, developing robust and interpretable computational models, and translating fused analytics into clinically meaningful outcomes. Overlapping data distributions, discrepancies in spatial and temporal resolution, and the complexity of high-dimensional data all pose enduring obstacles. While deep learning and other AI methods have made headway, open problems persist, particularly in generalizing models across sites, populations, and modalities, and in achieving clinically validated impact.

This Research Topic aims to accelerate innovation in multimodal data fusion and cross-disciplinary analytics for medical imaging. It seeks to gather pioneering work addressing the theoretical, methodological, and translational challenges inherent in synthesizing information from a variety of medical imaging and data sources.

Key goals include:

- Developing new computational frameworks or algorithms for integrating heterogeneous imaging and non-imaging data.
- Showcasing machine learning and AI-driven fusion strategies spanning beyond traditional deep learning paradigms.
- Advancing methods that improve interpretability, generalizability, and clinical utility.
- Encouraging benchmarking studies, comparative validation, and open access to resources for reproducibility and wider adoption.

Interdisciplinary submissions from medical imaging, biomedical engineering, clinical informatics, computer vision, and related fields are welcome. Relevant themes and topics include (but are not limited to):

- Multimodal and cross-modal fusion techniques: Algorithms for integrating two or more imaging modalities and/or combining image and non-image data.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
