Susan Back, MD
Attending Radiologist
Assistant Professor of Radiology

Dr. Back is an Attending Radiologist within the Division of Body Imaging, the Director of the Center for Pediatric Contrast-Enhanced Ultrasound (CPCU) and of the Section of Genitourinary Imaging, and an Assistant Professor of Radiology at the University of Pennsylvania. She joined the Department of Radiology in 2013 following completion of a Pediatric Radiology Fellowship at CHOP. She received her Medical Degree from Temple University School of Medicine in Philadelphia and completed residencies in Pediatrics and Radiology at CHOP and Virginia Commonwealth University, respectively. She holds dual board certification in Diagnostic Radiology and Pediatrics and a Certificate of Added Qualification in Pediatric Radiology.

Dr. Back is a member of the Society of Radiologist in Ultrasound, Society of Abdominal Radiology, American Institute of Ultrasound in Medicine, Society for Pediatric Radiology, American Roentgen Ray Society, Radiology Society of North America, and American College of Radiology. She serves as the Contrast-Enhanced Ultrasound Task Force Vice Chair for the Society of Pediatric Radiology and a Pediatric Ultrasound Community Leader for the American Institute of Ultrasound in Medicine.

In 2016, Dr. Back received the Certificate of Merit Award Education Exhibit from the Radiology Society for North America and the Thomas L. Slovis Award from the Society for Pediatric Radiology.

Through the CPCU she conducts monthly small group hands-on workshops on pediatric contrast enhanced ultrasound (CEUS) and provides support and education for clinical and research applications of CEUS within and outside of the department. Her research focuses on ultrasound and advanced ultrasound applications as well as genitourinary imaging. For example, she is engaged in prospective research of 3-D ultrasound in urinary tract dilation as well as contrast-enhanced ultrasound in pediatric trauma. Her clinical work supports the urology service in part through the development of protocols surrounding 3-D modeling and printing for surgical planning and innovations.

Dr. Back’s current work focuses on CEUS in the pediatric clinical setting for blunt abdominal trauma, renal and hepatic imaging, and developmental dysplasia of the hip; industry-sponsored evaluation of 3D renal US in urinary tract dilation; and the role of 3D modeling in complex genitourinary anatomy.
