From routine echocardiograms to innovative cardiac MRI techniques, Joe DiMaggio Children's Hospital Heart Institute uses heart imaging to heal hearts and save lives.
Our heart imaging program uses new, noninvasive techniques that offer a more accurate diagnosis. Having a clear picture of what’s going on inside your child’s heart helps us diagnose and treat your child.
What Is Cardiac Imaging?
Cardiac imaging helps us diagnose heart conditions. Imaging also guides cardiac surgeons and cardiologists during treatment. Finally, imaging is vital for your child’s recovery and follow-up, because it helps us see how the heart and blood vessels have responded to treatment.
We use a variety of techniques and high-tech imaging equipment to see inside the heart’s structures. Many imaging tests are noninvasive, meaning there are no needles involved. For the imaging tests that do involve a needle or sedation, we will make sure your infant or child is comfortable and doesn’t feel pain.
Why Choose Joe DiMaggio Children’s Hospital Heart Institute for Cardiac Imaging?
We combine compassionate care with advanced technology to help diagnose and treat children of all ages. We are known for:
- Leading the way in stress perfusion cardiac MRI:
We are one of the first pediatric hospitals, and still one of the few, to offer stress perfusion cardiac magnetic resonance imaging (MRI) in children. This noninvasive test uses a drug to mimic the stress of exercise on a child’s heart while having a cardiac MRI. An MRI uses a magnet, radio waves and a computer to take pictures of the heart. This test:
- Helps children avoid cardiac catheterization or any other invasive diagnostic tests
- Allows us to see how blood flows into/to the heart muscle while at rest and during stressful conditions
- Has helped us to assess/evaluate patients and diagnose cases of hypertrophic cardiomyopathy
- Using advanced echocardiography: We use 3-D echocardiography to assess ventricular function (how well the heart pumps blood) during treatment and diagnosis. An echocardiogram (echo) is a noninvasive test that uses ultrasound waves to create images of the heart. A 3-D echo is superior to standard 2-D because it allows us to see the entire heart, so we can better prepare for a child’s heart surgery or cardiac ablation.
- Working as a team to care for children: Our team of imaging specialists works with every subspecialty within cardiology. Imaging provides the window to see what’s going on inside a child’s heart. Together, we help diagnose, treat and heal children – keeping families in the center at all times. Meet our team.
Noninvasive Imaging Tests
Noninvasive means the imaging device is outside the body. The most common noninvasive tests include:
- Echocardiography (echo): This diagnostic procedure uses ultrasound waves to create images of the heart. An echo can help us identify congenital heart problems and monitor children after a heart transplant. For children under age 3, we offer a sedated echo, because it may be difficult for the child to stay still. Sedated means that we give your child medicine to fall asleep.
- Cardiac magnetic resonance imaging (MRI):
Cardiac MRI takes images of a patient's body using a magnet, radio waves and a computer. The MRI machine does not touch the child's body and does not use X-rays or radiation. To avoid exposing patients to radiation whenever possible, we use a cardiac MRI:
- When the echocardiogram is unclear or cannot give us enough diagnostic information
- To make a diagnosis and determine correct treatment
- For adult patients with congenital heart disease
- As part of surgical follow-up
- Stress perfusion MRI: We use a drug to mimic the stress of exercise on a child’s heart while taking an MRI. This new alternative to other, more invasive tests helps us see how blood flows to the heart during exercise.
- Computed tomography (CT) scans: A CT scan helps us evaluate structures outside the heart, including the veins, coronary arteries, aorta and aortic arch (the part of the aorta that bends). The CT scanner at Joe DiMaggio Children's Hospital Heart Institute uses very minimal radiation.
Minimally Invasive Imaging Tests
Minimally invasive means we introduce an imaging device inside the body. These tests include:
- Intravascular ultrasound: We use intravascular (inside the blood vessels) ultrasound during cardiac catheterization, a procedure that uses a needle stick in the leg to thread a tiny tube to the heart. The high-frequency sound waves of the ultrasound let us see inside the arteries.
- Transesophageal echocardiography (TEE): With TEE, we insert an ultrasound probe into the mouth and thread it into the esophagus so we can see the heart from behind, without the lungs in the way. A TEE gives us more detailed information about a child’s heart than a traditional echo. TEE is used before and after the majority of heart surgeries.
- Intracardiac echocardiography (ICE): ICE is an emerging imaging technique that helps us get a clearer image of the inside of the heart. We use it during cardiac catheterization, often along with treatment for a congenital heart defect.
