Welcome

Harry Marshall headshot

I'm an abdominal radiologist at Vanderbilt University Medical Center. I run clinical imaging trials to improve how we practice radiology, whether it's testing AI tools, refining MRI protocols, or rethinking how we teach diagnostic interpretation.

I've built this site to share my research and teaching material. Whether you're here to learn, collaborate, or just browse, I hope you find something that sparks your interest.

Research

MRI of liver with lesion

My research focuses on improving diagnostic imaging through clinical trials. I'm particularly interested in studies that evaluate both radiologists and machine learning tools in real-world settings — and how we can design them to be more rigorous, relevant, and scalable.

Click below to explore current projects, selected publications, and the tools we're building to support multi-reader studies and image-based evaluation. You can also view my full list of publications on Google Scholar or visit my ORCID profile.

Teaching

Fibrotic liver elastography

Teaching is one of the most rewarding parts of my work. I regularly teach medical students, radiology residents, and fellows, and have created a series of lectures spanning a wide range of topics in abdominopelvic imaging — from diffuse liver disease and prostate MRI to dual-energy CT and colorectal cancer staging.

This section features recorded presentations and downloadable PowerPoint decks. Whether you're reviewing foundational material or diving into more advanced topics, I hope you find these resources useful.
