She has been very active in the Radiologic Society of Normal America, the American Roentgen Ray Society, and the Society of Computed Tomography. Dr. Siegel’s teaching accomplishments have been recognized by the Teacher of the Year award at the Mallinckrodt Institute of Radiology and the Master Teacher Award in Radiology from the State University of New York.

Dr. Siegel has written a comprehensive textbook on pediatric body computed tomography, (Pediatric Body CT) now in its 2nd edition. She also has written the definitive textbook on pediatric ultrasonography (Pediatric Sonography), which is now into its 4th edition. In addition, she has been the editor of a larger general book on the practice of ultrasonography (The Practice Of Ultrasonography) in children and adults and several Magnetic Resonance Clinics of North America that were devoted to pediatric MRI. Dr. Siegel has been active in pediatric radiology research throughout her career and has made contributions related to the assessment of radiation doses from diagnostic imaging and oncologic applications of CT and MRI. One current area of research focuses on use of new technologies for dose reduction in CT. Another area addresses the use of whole body MR for staging of common pediatric tumors and she is conducting a multicenter trial in this area.

In addition, she is a member of the Response Assessment Core (IRAC) at Washington University, which is funded by the National Institutes of Health. In this role she is responsible for response assessment measurements on NIH and drug sponsored studies in children and adults with cancer. Over the last decade Dr. Siegel has dedicated time to developing accreditation standards for CT body imaging and most recently for cardiac imaging for the American College of Radiology. For the last four years, Dr. Siegel has also devoted time to being chair of the diagnostic imaging committee for the Children’s Oncology group and is initiating new standards for oncologic imaging in children. She is a well recognized lecturer and has participated in numerous national and international conferences.
