UW Radiology

The Department of Radiology at the University of Washington is an academic department providing highly specialized care to patients through state-of-the-art diagnostic imaging and imaging-guided therapies.


Fred Hutch Cancer Center

Fred Hutch Cancer Center is a world-class cancer treatment center that unites doctors and researchers, serving as UW Medicine's cancer program.


Our imaging research addresses multiple clinical challenges related to breast cancer. We are utilizing new imaging approaches, such as advanced diffusion-weighted and contrast-enhanced MRI techniques, novel post-processing tools, and working to translate promising technologies to clinical practice through validation in clinical trials.

Active Studies

  • DW-MRI tailored for early detection of mammographically occult breast cancer in women with dense breasts

    In this study, we aim to implement novel technical optimizations to improve breast cancer detectability on DWI in women with dense breasts. Results of this study will provide valuable information as to the potential of using DWI as a screening tool that complements x-ray mammography and is faster, less expensive, and safer than DCE MRI for earlier detection of malignancy in women with dense breasts.

  • MRI Characterization of Biological Risk of Ductal Carcinoma in Situ (DCIS)

    The overall objective of this project is to develop robust advanced multiparametric breast MRI markers and radiomic signatures to characterize DCIS risk. Successful results of this study could lead to a decrease in unneccessary biopsies of calcifications and provide accurate assessments of DCIS risk of progression to invasive disease and recurrence after treatment.

  • Functional MRI Signatures of Treatment Response to Therapy for Breast Cancer

    The goal of this research is to improve breast cancer treatment by identifying novel imaging markers of response to therapy in different cancer types. Exciting advances in treatment approaches increase the need for new tools to quantify response and assess treatment efficacy in vivo.

  • Advanced Methods for Breast Cancer Screening

    CESM (contrast-enhanced spectral mammography) and ABMR (abbreviated breast MRI). The purpose of this study is to learn if two new breast cancer screening tests are effective in detecting breast cancer. If these tests are similar to standard breast MRI, they may offer additional screening options at lower cost for more women.

  • Deep Learning

    Despite improvements in treatment and screening, breast cancer remains the 2nd most common cause of cancer related death among U.S. women. Using deep learning approaches , we aim to develop models that can detect cancer with high specificity and sensitivity, and predict the future risk of developing breast cancer in screening populations.
