      Collapse Overview
      Peder Larson, PhD, is an Assistant Professor in Residence and a Principal Investigator in the Department of Radiology and Biomedical Imaging at the University of California, San Francisco. Dr. Larson's research program is primarily centered around developing new MRI scanning and reconstruction technology for improved clinical outcomes. These developments in his group are aimed at several applications:

      Metabolic imaging methods using hyperpolarized carbon-13 MRI
      This exciting new imaging modality in currently in Phase I and Phase II clinical trials for oncologic applications, and Dr. Larson's group is responsible for the scanning methods used in these trials. His group is also developing new methods, aimed to provide faster, more accurate and higher-resolution imaging as well as generate new types of information and image contrast.

      Semi-solid tissue MRI
      Conventional MRI does not detect semi-solid tissues, such as tendons and cortical bone, as well as components of myelin, ligaments, menisci, other connective tissues, and lung parenchyma. Dr. Larson’s groups is actively developing advanced semi-solid tissue MRI methods, and pursuing clinical applications in tendon, bone, myelin, and lung imaging.

      Recently introduced hybrid PET/MRI systems combine the exceptional soft-tissue contrast of MRI with the functional contrast of PET. Dr. Larson's group is developing MRI methods for these systems to provide improved quantification, image quality and SNR in a clinical setting.

      Dr. Larson is an active member of International Society for Magnetic Resonance in Medicine, the Institute for Electrical and Electronics Engineering, the UC Berkeley and UCSF Graduate Group in Bioengineering, and the California Institute for Quantitative Biosciences.
