Interventional Radiology
CHOC has the most advanced imaging equipment available, calibrated just for kids. CHOC is proud to be the first in Orange County to offer pediatric interventional radiology (IR). From blood clots to tumors, IR treats the toughest medical problems no matter how big or small.
Since every child is different, every treatment is different. For this reason, procedures for specific targeted areas can be overwhelming and complicated. Yet, IR is comprehensive enough to access, diagnose and treat almost every part of the body with a needle.
CHOC’s radiology team includes a pediatric board-certified interventional radiologist who helps bridge diagnosis and treatment. CHOC has been designated a Diagnostic Imaging Center of Excellence® (DICOE) by the American College of Radiology (ACR) for best-quality imaging practices and diagnostic care. With a foundational knowledge of medical imaging and expertise, our interventional radiologist partners with other specialists like the Heart Institute and primary care to treat many of today’s toughest medical problems.

Palliative Care
Palliative care is specialized, additional medical care for people living with a serious illness. This type of care is centered around providing relief from the symptoms and stress of illness to enhance quality of life. The goal is to improve quality of life for both the patient and the family.
Palliative care is based on the needs of the patient, not on the patient’s prognosis. It is appropriate at any age and at any stage in a serious illness, and it can be provided along with curative treatment. Palliative care is adjacent to hospice and end-of-life care, but it is not actual end of life care.
CHOC’s Palliative Care program aims to enhance the level of support and reduce the amount of suffering experienced by patients with complex medical conditions, as well as for the people who love them and the healthcare team that cares for them.
The Palliative Care Team supports patients by:
- Providing initial consultations and follow up encounters in the hospital, OPI, and other clinics
- Easing pain and managing symptoms and side effects
- Fostering communication between families and health care providers
- Identifying goals of and aligning all involved with the medical care plan
- Delivering effective educational programs to healthcare staff
As the only children’s hospital in Orange County with a pediatric palliative care program, this team is available to provide care in the inpatient and outpatient setting, in partnership with other healthcare providers.
A palliative care consultation is appropriate for patients with serious illnesses who would benefit from enhanced symptom and, or pain management and an increased focus on improving quality of life and family support. During a consultation, families and members from our care team would discuss the goals of care, care preferences, advanced care planning and any spiritual and/or psycho-social distress.

Radiology
CHOC Children’s Specialists pediatric radiologists provide the only specialized pediatric imaging services in the region. CHOC Children’s uses cutting-edge technologies to obtain the highest quality image, while at the same time reducing the patient’s exposure to radiation. This is especially important for children whose conditions require repeated studies over the years.
Our expert physicians and staff are dedicated to using the lowest dose of radiation necessary, without sacrificing the quality of images required for quick and accurate diagnoses. Many children are imaged in adult facilities where radiation doses can be up to 50 percent higher than at CHOC.
We are accredited by the American College of Radiology and follow the guidelines of the Image Gently® campaign, so you can rest assured that your child will receive the safest radiology services available.
The CHOC Children’s Radiology Department is one of only a handful of hospital radiology departments in the country to offer a child life specialist. Child life specialists have been shown to decrease the amount of sedation necessary for children undergoing imaging tests. From the imaging suites to our family lobby, the Imaging Department has been designed to be a calm and inviting unit for children of all ages—from infants to teens and young adults. The unit features a number of private areas that allow child life specialists, caregivers and doctors the opportunity to interact with patients as need before or after an exam. CHOC Children’s offers patients special goggles to use during MRI scans. These video goggles allow the patient to watch their favorite movie or television show while undergoing their MRI scan and have been proven to reduce the number of patients needing sedation for MRI procedures.

Neurology
The CHOC Specialists Neurology Specialty Division at CHOC Children’s is available for consultation 24-hours-a-day, 7 days a week and provides diagnostic services, medical treatment, and follow-up care to infants, children, and adolescents who have suspected or confirmed neurological disorders. Our pediatric neurologists manage and treat a variety of patients including those with epilepsy disorders, neuromuscular disorders and spasticity.
A pediatric neurologist has completed a residency in pediatrics and had additional training in adult and child neurology. All our pediatric neurologists have certification or are eligible for the American Board of Psychiatry and Neurology (with special qualifications in child neurology). Our group also has pediatric neurologists with Board certification in Clinical Neurophysiology (Epilepsy and Neuromuscular diseases), Palliative Care, and Neurodevelopmental Disabilities.
Pediatric neurologists combine the expertise in diagnosing and treating disorders of the nervous system (brain, spinal cord, muscles, nerves) with an understanding of medical disorders in childhood and the special needs of the child and their family. In many cases, pediatric neurologists work as a team with pediatricians or other primary care doctors. In addition, pediatric neurologists may work with other pediatric specialists to care for children with more complex or serious medical issues, such as epilepsy, birth defects, or developmental delay.
CHOC Hospital Comprehensive Epilepsy Program is recognized by the NAEC as a Level 4 epilepsy center. Level 4 epilepsy centers have the professional expertise and facilities to provide the highest level medical and surgical evaluation and treatment for patients with complex epilepsy.
The following conditions may be best treated by a pediatric neurologist:
- Epilepsy and seizures — including intensive long term video EEG monitoring for epilepsy and related disorders
- Motor system disorders — including tics, Tourette’s Syndrome; neuromuscular diseases, including congenital myopathies, muscular dystrophy, hypotonia and other genetic muscular disorders; and cerebral palsy
- Headaches with neurological findings or patients who have failed first line medications
- Developmental and behavioral disorders — including learning disabilities, ADHD, developmental disorders and autism through the Thompson developmental center
- Neurogenetic and neurometabolic disorders — including neurodegenerative diseases such as mitochondrial disorders, neurofibromatosis, tuberous sclerosis complex, Rett Syndrome and Down Syndrome
- Neuroimmunological disorders — including dermatomyositis and post-infectious encephalopathy
- Neurological aspects of head injuries, brain tumors, brain malformations, and hydrocephalus
- Complications of central nervous system infection
Clinical services are complemented by the multidisciplinary care provided by other CHOC Specialists, nurses, pharmacists, EEG lab technicians, therapists, clinical dietitians, child psychologists and social workers at CHOC Children’s.
