Thomas Ptak

Thomas Ptak is a Professor in the Radiology department at the University of Massachusetts Chan Medical School (T.H. Chan School of Medicine). With dual expertise in clinical medicine and research, his work bridges emergency radiology, trauma imaging, and biomedical applications of CT technology.

• Medical Degree from Albany Medical College
• Primary Affiliation: UMass Chan Medical School

Research Focus: Ptak's research spans two distinct domains:

• Medical Imaging: Pioneering CT protocols for trauma patients, including dual-energy CT, intra-arterial contrast administration, and perfusion imaging. His work on ACR Appropriateness Criteria has standardized imaging practices for trauma cases.
• Environmental Science: Earlier contributions to groundwater contamination modeling and aquifer dynamics remain evident through MeSH term associations, though recent publications exclusively focus on clinical radiology.

Key Publications (2018-2025) emphasize:

• Optimizing trauma imaging workflows
• Advancing CT perfusion techniques for brain injury assessment
• Developing evidence-based imaging guidelines for the American College of Radiology
• Comparative studies of imaging modalities in emergency settings

Collaborative Networks include partnerships with:

• Jerry Rhea at UMass Chan
• Emergency medicine specialists like John Morrison
• Imaging researchers in the ACR Appropriateness Criteria committees
