An ultrasound is an imaging scan that can help diagnose specific types of cancer. Ultrasounds use high-frequency sound waves to create sonograms, or two-dimensional images of the inside of the body. A licensed technologist will use a transducer wand to send out the sound waves, and as they reflect off organs and tissues, a computer translates the echoes into images.

Ultrasounds only take a few minutes and are very safe. However, the images produced by an ultrasound are less detailed than those produced by an MRI or CT scan. On a sonogram, unusually dense tissues (such as tumors) will show up as darker patches on a lighter background of healthy tissue, but the extent of a cancer may be hard to determine.

Although they produce less detailed images than certain other methods, ultrasounds may be recommended if:

  • There is a possibility that a lesion might be a fluid-filled cyst instead of a tumor (ultrasounds can distinguish the two based on echo patterns, whereas other imaging scans cannot tell the difference)
  • A physician suspects a soft tissue abnormality that traditionally doesn’t show up well on X-rays
  • A physician needs to see if cancer has spread into the blood vessels, especially in the liver or pancreas (this can be done with a special ultrasound machine called a Doppler Flow machine)
  • Radiation exposure is a concern (ultrasounds do not use radioactive waves, the way that CT scans, MRIs and X-rays do)

An ultrasound may also be done to guide a biopsy, which is a different kind of test in which a small sample of tissue is taken from a tumor. A real-time ultrasound image can help a patient’s physician more accurately guide the biopsy needle into the lesion.
