Clinical Application

Currently low for direct clinical implementation. The proposed strategies require substantial interdisciplinary collaboration, infrastructure investment, and empirical validation before they can be operationalised in clinical neuroimaging workflows. The AI-driven optimisation component in particular requires large, well-annotated training datasets and regulatory-grade validation. In the Australian context, this work is most relevant to research institutions with neuroimaging capabilities, such as those affiliated with the Australian Brain Alliance and the National Imaging Facility (NIF). The TGA would need to evaluate any novel chemical probes proposed for human use under the Therapeutic Goods Act 1989, including assessment of safety, efficacy, and manufacturing standards. PBS listing of novel imaging agents would require PBAC evaluation demonstrating clinical and cost-effectiveness — neither of which is addressed in this paper. RACGP and RANZCR guidelines for neuroimaging do not currently incorporate the probe-equipment integration frameworks proposed here. Australian researchers may find the conceptual framework useful for grant applications (e.g., NHMRC Ideas Grants) targeting translational neuroimaging innovation. Primarily relevant to neuroscience researchers, neuroimaging physicists, and biomedical engineers working on preclinical or translational brain imaging. Potential downstream relevance to clinical neurologists, neuroradiologists, and neurosurgeons as the proposed frameworks mature toward clinical translation.

Abstract

Recent years have seen significant progress in imaging technology, which has deepened our understanding of the brain. However, challenges remain in detecting nanoscale structures like the extracellular space and mapping complex neural networks. Various chemical probes have been developed to improve the imaging precision of microstructures and functional imaging. Yet, the integration of imaging technologies and probes stays underdeveloped. Differences in disciplinary paradigms, unclear quantitative and qualitative relationships, and a lack of optimized cross-functional orchestration are the main causes of this problem. In this paper, we propose potential strategies to achieve deep integration of probes and equipment for high-quality imaging. Specifically, we advocate for three main approaches: (1) designing imaging sequences driven by probe properties, (2) constructing quantitative dose-effect models, and (3) leveraging artificial intelligence for system optimization. Importantly, these strategies establish an adaptable framework that will facilitate the seamless integration of emerging probe and equipment technologies in future brain science research. Ultimately, this enhanced integration promises to advance our knowledge of brain function and structure.
