The CHOC Difference

We offer low-dose X-ray and fluoroscopy specially calibrated for our young patients. We are the only hospital in Orange County to provide pediatric 3D CT and MRI heart imaging for diagnosing complex heart problems and planning for surgery.

Our flash CT scan machine produces detailed images of the smallest vessels—even in infants—in a matter of seconds while using a very lose dose of radiation. This machine allows our technologists to customize the scan according to a child’s size and symptoms while protecting dose-sensitive organs. Learn more about our Radiology Department.
