Robert Flavell


Chief, Molecular Imaging and Therapeutics

Dr. Robert Flavell is a radiologist who cares for both adults and children, and specializes in nuclear medicine, the use of small amounts of radioactive materials to evaluate organ systems. He is chief of molecular imaging and therapeutics for the UCSF Department of Radiology and Biomedical Imaging.

In research, Flavell focuses on developing new methods of diagnosing and treating cancer using molecular imaging technology, which shows what is taking place in the body at a cellular and molecular level.

After earning a doctorate in chemical biology at the Rockefeller University, Flavell earned his medical degree at Weill Cornell Medicine. At UCSF, he completed a residency in diagnostic radiology, followed by a fellowship in nuclear medicine.

    Imaging Study of [89Zr]DFO-YS5 for Detecting CD46 Positive Malignancy in Multiple Myeloma

    Defined as the rate of lesions with positive uptake when compared against 18F-fluorodeoxyglucose (FDG) PET/computed tomography (CT) positivity. Sensitivity estimated based on lesion level without considering the location of the le...

    Magnetic Resonance (MR) Imaging With Hyperpolarized Bicarbonate (13C) to Measure Tissue pH in P...

    The feasibility of a study will be determined by the ability to generate adequate signal to noise ratio to measure acidity (pH) in tumor or adjacent healthy tissue. This study will be considered successful if the 13C bicarbonate (...

    PET Imaging Study of 89Zr-DFO-YS5 in Men With Prostate Cancer

    For Cohort A, the optimal time point will be selected based on optimal maximun Standardized uptake value (SUVmax) of metastatic lesions, and ratio of SUVmax to blood pool. Due to the limited samples, the investigator will use all ...
