Conversational AI Is Cracking the Neuroimaging Bottleneck
October 21, 2026
Summary:
A multi-institutional team led by Lehigh University has received a four-year, $2.8 million NIH grant to develop UniBrain, an all-in-one artificial intelligence platform designed to consolidate fragmented neuroimaging pipelines. By unifying preprocessing, segmentation, multi-modal integration, and disease prediction into a single deep learning architecture, paired with a conversational agentic interface, UniBrain aims to turn raw MRI scans into interpretable diagnostic biomarkers in minutes rather than months.
Key Facts:
- $2.8M NIH Initiative: Funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB), the four-year project is spearheaded by Lehigh University in collaboration with Massachusetts General Hospital/Harvard Medical School, Emory University, and the University of Pittsburgh.
- Unified Pipeline Architecture: UniBrain eliminates the need to shuffle brain imaging data across disparate, specialized software packages by combining image registration, tissue segmentation, feature extraction, and network-level disease prediction into one cohesive system.
- Agentic AI Interface: The system incorporates a conversational, ChatGPT-like interface that allows clinicians and researchers without computational backgrounds to upload raw MRI files, ask diagnostic questions in plain language, and receive automated, interpretable biomarker reports.

Extracting clinically actionable biomarkers and neuroscientific insights from brain scans remains one of the most computationally tedious bottlenecks in medicine. Currently, translating raw neuroimaging data into diagnostic predictions requires researchers to shepherd massive datasets through a fragmented sequence of specialized, single-purpose software packages, one for motion correction, another for anatomical registration, a third for tissue segmentation, and separate tools for network modeling.
For extensive clinical cohorts, this manual pipeline can take weeks or even months to execute, creating a substantial barrier for clinicians and neuroscientists who lack advanced coding and computational infrastructure.
To solve this fragmentation, an interdisciplinary consortium led by Lifang He, PhD, associate professor of computer science and engineering at Lehigh University, has been awarded a four-year, $2.8 million grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) to develop UniBrain, an artificial intelligence platform engineered to consolidate the entire neuroimaging workflow into a single, automated architecture.
Consolidating Fragmented Neuroimaging Workflows
The initiative brings together computer scientists, radiologists, bioengineers, and neuroscientists across four leading research centers: Lehigh University, Massachusetts General Hospital/Harvard Medical School (led by Xiang Li), Emory University (led by Carl Yang), and the University of Pittsburgh (led by Liang Zhan).
Traditional pipelines handle key computational stages, such as spatial normalization, skull stripping, volumetric segmentation, structural/functional connectome mapping, and pathology classification, as isolated, disconnected tasks. This modular approach compounds error propagation, requires extensive file format conversions, and demands manual quality assurance at every transition.
UniBrain re-engineers this pipeline from the ground up by deploying end-to-end deep learning models capable of simultaneous preprocessing and downstream neural network analysis. Crucially, the platform harmonizes complementary data across multiple imaging modalities, including structural MRI, functional MRI (fMRI), and diffusion tensor imaging (DTI), within a unified latent space.
Preliminary tests demonstrate that UniBrain’s integrated framework matches or exceeds the precision of conventional multi-tool pipelines while reducing computational overhead from weeks to minutes.
“This is a very ambitious project,” said Dr. He. “We’re developing and deploying new AI tools to do the analysis while rethinking the entire neuroimaging analysis process from start to finish within a unified platform. We need experts in many fields working together to solve problems of this scale.”
An Agentic, Conversational Interface for Medicine
Beyond building the computational backend, the consortium is developing an agentic AI framework designed to democratize advanced neuroimaging for frontline medical professionals.
Operating through an intuitive, conversational interface modeled after large language model assistants, the agentic system allows physicians and neuroscientists to upload raw DICOM or NIfTI imaging files and interact with the data using natural language prompts. Clinicians can query specific anatomical anomalies, request automated regional volume comparisons, or track functional connectivity changes over time.
In response, UniBrain autonomously selects the optimal preprocessing parameters, runs the underlying deep learning classifiers, and generates transparent, interpretable clinical reports complete with visual saliency maps highlighting subtle disease biomarkers that human visual inspection might overlook.
Security, Privacy, and Broad Clinical Reach
Because clinical neuroimaging involves sensitive patient health information, the platform incorporates advanced AI security and privacy-preserving protocols overseen by Lehigh computer scientist Lichao Sun, PhD, ensuring compliance with medical data governance.
Additional key collaborators on the initiative include Quanzheng Li, PhD, Randy Hirschtick, MD, Daniel Barron, MD, PhD, Boadie Dunlop, MD, and Ying Ding, PhD, providing clinical validation across psychiatric and neurodegenerative patient cohorts, including Alzheimer’s disease, major depression, and related neurological disorders.
“This represents the next generation of AI for scientific discovery,” He noted, “and it could help scientists make discoveries that weren’t possible with earlier tools.”
By bridging the gap between raw medical imaging and rapid, interpretable diagnostic discovery, UniBrain aims to provide an accessible, standardized foundation for precision neurology and translational neuroscience.
