About Dr. Nicolaus A. Wagner-Bartak
Dr. Nicolaus Wagner-Bartak joined MD Anderson Cancer Center in 2010 as Assistant Professor in the Department of Abdominal Imaging and was promoted to Professor in 2022.
Dr. Wagner-Bartak graduated from the University of Virginia followed by medical school at the University of Pennsylvania. He completed his diagnostic radiology residency at the University of Texas in Houston, and fellowship in Abdominal Imaging and Intervention at Massachusetts General Hospital/Harvard Medical School. He received his board certification in Diagnostic Radiology from the American Board of Radiology.
Dr. Wagner-Bartak serves as Director of Clinical Operations for the Department of Abdominal Imaging and previously served as Deputy Chair, ad interim.
Dr. Wagner-Bartak's clinical and research interests include CT technique optimization for abdominopelvic applications, including tailoring the examination to the patient's needs and oncologic history, improving exam sensitivity and specificity, CT radiation dose optimization, and lymphoma imaging. He is involved in multiple hypothesis-driven research projects, both as a PI and a collaborator and serves as a consultant in the Lymphoma treatment planning clinic. He is the radiologist lead on multiple ongoing clinical trials, the majority of which involve assessing tumor response to novel chemotherapeutic regimens and targeted cancer therapy.
Dr. Wagner-Bartak mentors and teaches medical students, radiology residents, and fellows from UT Health Science Center, Baylor College of Medicine, and MD Anderson.
