Our guest today is Dr. Vesa Kiviniemi, a radiologist and researcher at Oulu University in Finland.

Dr. Kiviniemi’s recent focus has been on using an extremely high-speed MRI technique called MREG. This technique allows for the collection of an entire volume of data with a TR of just 100 milliseconds, using a stack-of-spirals approach. The reason he values this technique so much is that it enables him to examine various types of brain pulsations, including cardiac and respiratory pulsations, as well as what he refers to as glymphatic or CSF pulsations.

In this episode, Dr. Kiviniemi explores how he has applied this technique in his research. He also discusses the history of our understanding of the glymphatic system, its potential functions, the many unknowns surrounding it, and the opportunities it presents for future research. Among other topics, he explains why using this high-speed technique might complement—or in some cases even be better than—slower approaches in certain ways.

We hope you enjoy the conversation!

Today our guest is Dr. Angie Laird, who trained as an imaging physicist, but has evolved into a cognitive neuroscientist and a true pioneer in meta-analysis of fMRI data. Dr. Laird has spent the bulk of her career developing novel data analysis algorithms, neuroscience informatics tools, and neuroimaging ontologies to yield analytic strategies for improving investigations into functional brain networks of healthy individuals as well as in populations with psychiatric and neurologic diseases and disorders. Early on she has seen the untapped value in meta-analysis, and has fostered growth in this fundamentally important area in functional brain imaging. Dr. Laird received her B.S. in Physics from Florida State University in 1998, and her Ph.D. in Medical Physics from the University of Wisconsin-Madison in 2002. She was a faculty member at the Research Imaging Institute of the University of Texas Health Science Center in San Antonio from 2004-2012, and currently she is Professor and Director for Imaging Science at Florida International University in Miami. Along with her development of meta-analysis tools and her own research, she plays a central role in the Adolescent Brain Cognitive Development (ABCD) consortium which is the largest long-term study of brain development and child health in the United States. This was a great conversation that spanned the early culture of fMRI research, early efforts towards data sharing, to the current practices today where data sharing and analyzing data across studies and from large shared datasets is becoming the norm. We also spent time talking about the origin, logistics, and impact of the ABCD project. We hope you enjoy it! Episode producers: Omer Faruk Gulban Xuqian Michelle Li…

Dr. Vince Calhoun is the founding director of the tri-institutional center for translational research in Neuroimaging and Data Science (TReNDS) which is a consortium formed by Georgia State University, Georgia Tech, and Emory University. In this part 2 of Peter and Vince’s discussion, they dive further into addressing the challenges that fMRI and other modalities face in finding useful information about psychiatric disorders that can be used clinically. They talk about what neuroimaging has taught us about schizophrenia, as well as the goals and challenges of establishing clinical relevance. They also talk a bit about the importance of a data driven approach to development of processing methods, as well as variability in fMRI data, and the challenges and opportunities that big data sets offer, the promise of data fusion, and multivariate modeling. Lastly, they also discuss his latest work in deep learning and what it offers, and spend quite a bit of time discussing data driven approaches vs model driven approaches. This discussion was an outstanding perspective builder. We hope that you enjoy it! Episode producers: Omer Faruk Gulban Xuqian Michelle Li…
