Ultrasound Our medical clinic provides on-site (please call for availability) diagnostic ultrasound for many conditions, including thyroid nodules, kidney stones, cholecystitis or gallbladder stones, and many other conditions that require a more detailed evaluation using this safe and non-invasive method. This test involves an ultrasound technician gently moving a cellphone-sized probe on the surface of the skin, using special gel as a lubricant. This is completely painless and usually takes 20-30 minutes. Echocardiogram Ultrasound of the heart is called an echocardiogram, and it is done when a heart murmur present on a physical exam or another heart test (such as an EKG or chest X-ray) show a possible heart problem. Echocardiogram (or echo) gives much more information about the functioning of the heart than most tests, including the thickness of cardiac muscle, heart valves function, and pressures inside of the heart. Echo is a completely safe and painless test.
