Department of Diagnostic Imaging

Departmental Focus

St. Jude Children’s Research Hospital’s Department of Diagnostic Imaging is responsible for providing St. Jude patients with state-of-the-art diagnostic and therapeutic imaging based assessments and therapies. The vision of the department is a commitment to world-class radiologic research and patient care in diagnostic radiology. Our mission is to advance the treatment of children with catastrophic diseases by providing excellence in the diagnosis and management of children with cancer and related disease. Diagnostic Imaging consists of the sections of Body Imaging and Neuroimaging and the Nuclear Medicine clinic.

The primary focus of our efforts in diagnostic imaging is to provide outstanding clinical radiology in all areas germane to children with catastrophic diseases (primarily cancer, sickle cell disease, and related infectious diseases) through optimal imaging procedures and the exploration of novel imaging applications and developmental research. As the only broad-based pediatric radiology program committed largely to childhood cancer, Diagnostic Imaging has had a fundamental role in improving the quality of patient care and outcomes at St. Jude while exploring new technologies to enhance diagnostic accuracy, document response to traditional and new molecular signaling agents, and study the effects of cancer and oncologic therapeutics acutely and in long-term survivors.

The Diagnostic Imaging Department is comprised of nine faculty radiologists, one faculty nuclear medicine physician and a medical physicist. Our faculty serve as principal investigators and coinvestigators on scientific protocols with primary and secondary imaging objectives. They participate in a variety of central reviews for protocol-based imaging studies initiated by St. Jude investigators, as well as cooperative groups such as the Children’s Oncology Group (COG), the Pediatric Brain Tumor Consortium (PBTC), and National Heart Lung and Blood Institute (NHLBI).

As of 2011, Diagnostic Imaging qualified for a Center of Quantitative Imaging Excellence (CQIE) designation awarded by the National Cancer Institutes and American College of Radiology Imaging Network. To receive this prestigious award, a cancer center must pass an initial assessment and then undergo annual requalification for the next three years.

Diagnostic Imaging provides a comprehensive array of qualitative and quantitative imaging assessment and techniques to St. Jude patients:

  • MRI (Magnetic Resonance Imaging)
  • Functional MRI
  • DEMRI (Dynamic Enhanced Magnetic Resonance Imaging)
  • CT (Computed Tomography)
  • PET/CT (Positron Emission Tomography)
  • X-Rays and Fluoroscopy
  • Ultrasound and Ultrasound Contrast Agents
  • Image-guided Therapies and Procedures
  • Scintigraphy and SPECT/CT
  • DEXA and Quantitative CT for Bone Density
  • Post-processing Vision Laboratory
