who needs an echocardiogram
Home > Cancer Resources > Tests and Procedures > Imaging Tests > Echocardiogram. An echocardiogram (echo) is a test that helps doctors evaluate the strength and function of a childâs heart. The test uses sound waves to create a picture of the heart. The above video demonstrates a echocardiogram in two children undergoing cancer treatment.
