Ultrasound

An ultrasound exam uses high-frequency sound waves to look at internal organs. As the sound waves are bounced off the body, they produce images that identify the size, location and shape of internal structures.

An ultrasound is done to examine the thyroid gland or the abdominal and pelvic regions. It can detect cysts and masses. In obstetrics, ultrasounds assess the growth and well-being of the foetus. A nuchal translucency ultrasound is part of the Integrated Prenatal Screening (IPS) test to assess a baby’s risk of having Down Syndrome.

The HGH Diagnostic Imaging Department provides specialized ultrasound exams such as carotid Doppler, small part, thyroid, breast, shoulder and echocardiogram.
