William D. Middleton, MD

Professor of Radiology

Clinical Expertise:

William D. Middleton, MD, is a professor of radiology in the abdominal imaging section for WashU Medicine’s Mallinckrodt Institute of Radiology (MIR). Middleton, who joined the MIR faculty in 1987, is renowned for his expertise in ultrasound and his commitment to education. He’s credited as the architect behind the expansion and subsequent international recognition of the ultrasound service at MIR and has passionately promoted the subspecialty nationally.

Middleton’s technical skills as an ultrasonographer also led to dramatic increases in the use of Doppler to study abdominal vasculature and the use of ultrasound to guide percutaneous needle biopsies throughout the body. His textbook, “Ultrasound: The Requisites,” is considered the core text for ultrasound training.

In 2022, Middleton was honored with the Laurence A. Mack Lifetime Achievement Award from the Society of Radiologists in Ultrasound, which recognized his career of outstanding achievement in ultrasound research. He also received the Honored Educator Award in 2021 from the Radiological Society of North America and has received numerous MIR teaching awards throughout the years.
