Seattle Children’s Hospital’s Department of Radiology has the largest concentration of board-certified specialists in pediatric radiology in the Northwest, serving the needs of hospital-based physicians and community providers.

Twenty-one full- and part-time radiologists provide the complete array of pediatric radiology and medical imaging services. Our dedicated technical and radiologist staff members are uniquely trained and skilled in the care of infants, children, adolescents and their families. Our team of technologists obtains the best-possible images in a child-friendly environment while always keeping radiation safety in mind. We performed and interpreted more than 100,000 examinations in 2009.

Our team’s complete range of diagnostic and therapeutic imaging services includes radiography, computed tomography, fluoroscopy, magnetic resonance imaging, nuclear medicine, positron emission tomography, ultrasound, bone densitometry and 3-D imaging data reconstruction and quantitative image analysis. Children’s provides a complete range of diagnostic and therapeutic vascular and interventional radiology procedures. Therapeutic procedures include embolization, chemoembolization, thrombolysis, aspiration, drainage (pleural, peritoneal, biliary; nephrostomy, abscess), radiofrequency ablation of malignant and benign lesions, enteric access (gastrostomy, cecostomy), venous access (central line placement, PICC), joint and tendon injections, sclerotherapy and dilatation (esophageal, biliary, urinary; angioplasty).

Faculty members are authorities in neuroradiology, thoracic and abdominal imaging, musculoskeletal imaging, neonatal radiology, oncologic imaging, and vascular and interventional procedures. We are continually enhancing our digital information capability in such areas as speech recognition software for rapid report turnaround, PACS systems for soft copy reading and teleradiology review for off-hours consultation.

Children’s provides radiation oncology services through our affiliations with the Seattle Cancer Care Alliance and the University of Washington Medical Center. The Department of Radiology, in association with the University of Washington School of Medicine, educates radiology residents from four regional programs and trains fellows in a nationally recognized ACGME-approved pediatric radiology fellowship. Faculty members are engaged in a variety of research projects in the areas of neuro-oncology, neuroradiology, behavioral disorders, craniofacial malformations, functional brain imaging, oncology, medical informatics, and 3-D and high-resolution image analysis.
