Computerized Tomography (CT)​

A CT scan, also called a CAT scan, gives your doctor a closer look at your child's internal organs, bony anatomy, blood vessels and soft tissues, with more detail than a general x-ray.


An echocardiogram, echo or heart ultrasound, is a non-invasive, pain-free procedure using sound waves reflected off the surfaces of the heart to providing moving images of your child's heart.


An electrocardiogram is one of the simplest procedures used to evaluate the heart, taking only five to 10 minutes. The tracings allow the physician to see abnormal heartbeats that may indicate a heart problem.

Fetal Echocardiogram

Hepatobiliary Scan

Before a Hepatobiliary Scan, read this guide to help you explain to your child what will happen during the test.

Magnetic Resonance Imaging (MRI)

MRI is an imaging technique that uses a large magnet, radio frequencies and a computer to produce two- or three-dimensional images of the body.

Nuclear Medicine

Nuclear medicine scans u​se tiny amounts of radioactive materials (isotopes), a special camera and a computer to create images from various parts of the body.


A imaging test to detect cancer and neurological diseases, using special pictures taken after a tiny amount of a radioactive liquid is injected into a vein.

Proton Therapy

Proton Therapy is offered through the Northwestern Medicine Chicago Proton Center.


An imaging technology using high-frequency sound waves to see structures within the human body. It is noninvasive, there is no radiation and the exam is painless.


X-rays give Lurie Children's radiologists a completely noninvasive way to diagnose or assess problems occurring in various areas of your child's body.
