Roland Krug, PhD, has been at UCSF since 2003. Dr. Krug’s research interests include applying novel Magnetic Resonance Imaging and Spectroscopy tools to advance diagnosis of several musculoskeletal conditions with the ultimate goal to improve the quality of life of patients. He has a strong focus on identifying mechanisms that are responsible for low back pain as well as using novel tools such as MR guided high intensity focused ultrasound to treat this condition.

As a principal investigator, Dr. Krug has received substantial support from NIH including two R01, and a UH2/UH3. He is also a director of an U19 grant from the HEAL initiative to fight opioid addiction with a volume of 30 Million USD. Dr. Krug has more than 70 peer-reviewed articles published in the highest ranking journals in the field and serves as a reviewer for more than 15 scientific journals. He reviews grants for NIH as well as the German, Austrian, Dutch, and British National Institutes. He also teaches a class on MR pulse programming in the departmental master program.

Interests: Quantitative Bone and Marrow Imaging at the Hip, Muscle Imaging, Metal MRI, MR guided High Intensity Focused Ultrasound (MRgHIFU)
