Dr. Warren is a UW associate professor of radiology with a subspecialty interest in body imaging, including CT, MRI and ultrasound.

Patient Care Philosophy

My philosophy is to ensure that patients receive the highest quality imaging evaluation at the lowest possible radiation dose and in the safest fashion, and that image interpretation is coordinated with all aspects of the patient's clinical situation.

Personal Interests

Bicycling, hiking, sailing, kayaking, photography, general fitness and being a grandparent.

Clinical Interests

Obstetrical/gynecological ultrasound, including high-risk obstetrical ultrasound, CT and MRI imaging; evaluation of hepatic transplant candidates, Doppler ultrasound evaluation of hepatic, renal and pancreatic transplants; cardiac CT for evaluation of coronary artery disease; and CT and MRI evaluation of the vascular system.

Research Interests

Evaluation of methodology to reduce radiation dose in CT while maintaining excellent image quality; contrast-enhanced ultrasound applications, particularly in hepatic imaging; and optimization of image-guided minimally invasive techniques.
