About the department
The Department of Radiology, a recipient of the Quantitative Imaging Excellence (CQIE) designation, is the only broad-based pediatric radiology program committed largely to childhood cancer. Radiology has a fundamental role in improving the quality of patient care and outcomes for children with catastrophic diseases. We function in four sections: Body Imaging, Neuro Imaging, Interventional Radiology, and Nuclear Medicine. Our focus on exceptional and specialized imaging via multiple modalities to guide diagnosis and therapy monitoring is balanced with a drive to explore research technologies that enhance diagnostic accuracy. Our research endeavors span multiple facets of imaging: functional MRI (fMRI), spectroscopy, metabolic imaging, a growing Interventional Radiology section, as well as preclinical development of new imaging techniques. The department also offers a variety of education opportunities to support both new and experienced physicians.
Clinical operations: St. Jude Children’s Research Hospital provides clinical diagnostics in multiple imaging modalities including MRI, Nuclear Medicine, Ultrasound, CT, X-Ray, and Interventional Radiology. Our investments in advanced imaging technologies support new diagnostic procedures and low-dose radiation solutions. We are committed to reducing patient radiation exposure through routine evaluation of imaging protocols and dose. The Department of Radiology’s equipment and software are customized to support treatment protocols St. Jude’s patient population.

International Accreditation System for Interventional Oncology Services
The Department of Radiology is pleased to announce that we are now part of the Interventional Accreditation System for Interventional Oncology Services (IASIOS), the only program in the world that is exclusively certifying interventional oncology. By participating in the IASIOS Accreditation program, we are joining a global community of centers dedicated to the highest quality standards in IO.
We are proud to be leaders in this field, demonstrating a commitment to patient safety and providing high-quality cancer care.
Information about IASIOS accreditation can be found at www.iasios.org
Radiology research labs
The Department of Radiology has created focused labs in the areas of metabolic, functional, and structural imaging research. Each of these labs is actively pursuing cutting edge research for different aspects of childhood cancer including, but not limited to, observing metabolic changes that precede morphological changes as an early readout for treatment efficacy, strengthen the Cancer Center’s neuroscience initiatives with epidemiology, Psychology, and Radiation Oncology, and perform quantitative structural analyses of the CNS to guide interventions and assess response to cancer treatment to minimize impact on the developing brain. The department is currently recruiting faculty to lead two additional labs focused on molecular imaging and body imaging respectively.

Research Interests
- Evaluating the safety and effectiveness of interventional radiology therapies for children with cancer
Short Biography
Dr. Allison Aguado is a prominent pediatric interventional radiologist and leading expert in developing minimally invasive cancer treatments for children. She is known for her pioneering work in applying advanced therapies, such as Yttrium-90 radioembolization (TARE-Y90), to treat liver cancer in young patients.
Career and Expertise
Dr. Aguado earned her medical degree from Northwestern University and completed her residency in diagnostic radiology at St. Barnabas Medical Center in New Jersey. She then pursued three subspecialty fellowships, two at the Children's Hospital of Philadelphia (CHOP) in diagnostic and interventional pediatric radiology, and one in adult interventional radiology at Memorial Sloan Kettering Cancer Center (MSKCC). This unique training has provided her with the specialized expertise to deliver targeted, image-guided treatments to both children and adults with cancer. She has held faculty positions at institutions including Cincinnati Children's Hospital Medical Center and St. Jude Children's Research Hospital.
Key Achievements
- Pioneering Treatments: Dr. Aguado was an early adopter and tireless advocate for Yttrium-90 radioembolization (TARE-Y90) for pediatric liver cancer patients, a procedure she has performed since 2011.
- Research: Her research focuses on evaluating the safety and effectiveness of interventional radiology therapies for children with cancer, including targeted drug delivery and tumor ablation techniques.
- Recognition: She was honored with St. Jude's "Living Our Values" award for her significant contribution to advancing new therapies for children with catastrophic diseases.
- Publications: She has co-authored research articles on the successful use of TARE-Y90 in children with hepatoblastoma.
Dr. Aguado's work has had a profound impact on the delivery of pediatric oncology care, offering less invasive options and improving outcomes for young cancer patients.
