Ultrasound uses high-frequency sound waves to produce real-time tomographic images of the body. It does not use ionizing radiation, making it especially attractive to image children and pregnant women.

We use ultrasound as the imaging of choice for parts such as the gallbladder, thyroid, uterus, ovaries and scrotum. Ultrasound is frequently the first line imaging modality for imaging solid organs of the abdomen (liver, spleen, pancreas and kidneys) and vascular structures. Ultrasound is used for imaging deep pelvic structures, such as the bladder and prostate.

Our ultrasound equipment is state of the art, and our technologists and radiologists use the latest techniques. In addition to the gray-scale routine US, we also perform more specialized procedures:

  • Doppler ultrasound, a non-invasive method of evaluating blood vessels
    • Blockages to blood flow (eg, clot)
    • Narrowing of vessels
    • Tumors and congenital malformation
  • US-guided procedures
    • Needle biopsies – eg, lymph nodes, liver, kidneys, thyroid gland, prostate gland
    • Aspirations/drainage – eg, thoracentesis, paracentesis
  • Contrast-enhanced US – research activities
  • Sonohysterography
  • 3D/4D US imaging
