Imaging is key in diagnosing heart conditions. At Union Square, our cardiac and vascular imaging group offers a range of services that focus on you, your heart and its vascular system (the blood vessels that support your heart). These services include:

  • Echocardiography—an ultrasound that can show the size of your heart, its structure, and activity
  • Cardiac stress testing—sometimes called the “exercise test” and can help determine how well your heart handles the stress of exercise
  • Nuclear cardiology—a noninvasive imaging technique that shows how well your heart pumps blood
  • Carotid ultrasound—an ultrasound that provides an inside view of your carotid arteries, revealing their overall health
  • Upper and lower extremity arterial and venous sonography—ultrasound tests that show how well blood flows through the arteries in both your arms and legs
  • Abdominal aorta and iliac sonography—ultrasound tests that show how well blood flows through the arteries of your lower abdomen
  • Transcranial Doppler—an ultrasound test that measures the speed of blood flow through your brain
  • Renal artery sonography—an ultrasound that shows how well blood flows through the arteries that connect to your kidneys
