Services and modalities

Our imaging and radiology staff uses the newest, most advanced technology to provide the highest-quality diagnosis and treatment options for children. 

To help prepare your child for the diagnostic tests, please visit Starlight's radiology video walking the child step-by-step through an x-ray, CT scan and MRI

The department offers a wide variety of services, including:

Computed tomography (CT)

With a CT scan, an X-ray beam moves in a circle around the body. This allows for many different views of the same organ or structure. The X-ray information is sent to a computer, which interprets the data and displays it in two-dimensional form on a monitor.


Fluoroscopy is a study of moving body structures — similar to an X-ray “movie.” A continuous X-ray beam is passed through an area of the body and transmitted to a TV-like monitor. This allows the body structure and its motion to be seen in detail.

Interventional radiology

Interventional radiology is a subspecialty of radiology that uses imaging techniques during minimally invasive surgical procedures.

Magnetic resonance imaging (MRI)

MRI is a diagnostic procedure that uses a large magnet, radio waves and a computer to produce detailed images of organs and body structures. Unlike X-rays and CT scans, MRI does not use radiation.

Nuclear medicine

Nuclear medicine is a specialized area of radiology that uses a very small amount of radioactive substance to examine organ function and structure. This substance, called a tracer, emits radiation that is detected by a special camera.


Many imaging tests require children to remain completely still. If it is hard for your child to remain still, he or she may need to be sedated (receive medicine that will make him or her sleepy).


An ultrasound uses high-frequency sound waves and a computer to create images of soft body structures, such as tissues, organs and blood vessels.


X-ray is the process of creating images of the body using radiation to look at images of internal tissues, organs and bones.

EOS low-dose radiation scanner

Children’s Hospital of Wisconsin was one of the first two pediatric hospitals in the nation with an EOS low-dose radiation scanner. Doctors mainly use the scanner to help treat children with scoliosis (a curved spine). Now, families travel across the country for this cutting-edge care.
