Echocardiography is the specialty within sonography that focuses specifically on the heart and its structures. This specialized imaging technique uses sound waves to create images of the heart, allowing for assessment of cardiac function, the presence of heart diseases, abnormalities in heart structure, and monitoring of existing conditions. Echocardiographers are trained to perform various types of echocardiograms, including transthoracic and transesophageal echocardiograms, which provide detailed images of the heart chambers, valves, and surrounding structures.

The other specialties mentioned, while crucial in the field of medical imaging, do not concentrate specifically on the heart. Obstetric sonography pertains to the imaging of the female reproductive system, particularly during pregnancy. Vascular sonography focuses on the blood vessels and circulation, assessing conditions related to the arteries and veins. Abdominal sonography involves imaging organs within the abdominal cavity, such as the liver, kidneys, and gallbladder, rather than the heart itself. Thus, echocardiography is the correct choice for a sonography specialty centered on cardiac care.
