Dr. Stuart S. Sagel, 71, professor of radiology and former director of the chest radiology section at the Mallinckrodt Institute of Radiology in St. Louis, Mo., died Nov. 11.
Sagel was instrumental in shaping the Mallinckrodt Institute's leading role in the early days of body-computed tomography. He became known all over the world for his contributions to the field of chest radiology.
Born in Philadelphia, Sagel earned undergraduate and medical degrees at Temple University.
Sagel served as a medical intern at Maimonides Medical Center in Brooklyn, N.Y., and had additional postgraduate appointments at Yale University and the University of California, San Francisco.
From 1970-72, he was a staff radiologist at Wilford Hall U.S. Air Force Hospital in San Antonio, Texas.
Sagel joined Washington University in St. Louis in 1972 as an assistant radiologist.
In the late 1970s, the Mallinckrodt Institute became one of the first medical facilities to acquire a CT scanner. Sagel soon began publishing a series of influential scientific papers on using CT in the clinic. His work catapulted the scan into becoming a state-of-the-art diagnostic tool.
Sagel wrote and edited a textbook, Computed Body Tomography With MRI Correlation, that many radiologists regarded as the best in its field for decades.
Sagel is survived by his wife, Beverlee Sagel; sons Scott Sagel, Darryl Sagel and Brett Sagel; sister Nancy Florin; brother Bruce Sagel; and five grandchildren.
