Ultrasound imaging technique uses very high frequency inaudible sound waves to create a picture. The operator (Radiologist or Sonographer) use a probe and the ultrasound machine to capture patient’s internal organ images. Due to Ultrasound uses sound waves technology and NOT x-rays, it can be used on anybody, including pregnant women.

Its other advantages are:

Ultrasound imaging (also called ultrasound scanning or sonography) is a relatively inexpensive, fast and radiation-free imaging modality. Ultrasound is excellent for non-invasively imaging and diagnosing a number of organs and conditions, without x-ray radiation.

Ultrasound is extensively used for evaluating the kidneys, liver, pancreas, heart, and blood vessels of the neck and abdomen. Ultrasound can also be used to guide fine needle, tissue biopsy to facilitate sampling cells from an organ for lab testing (for example, to test for cancerous tissue).

Ultrasound imaging and ultrasound angiography are finding a greater role in the detection, diagnosis and treatment of heart disease, heart attack, acute stroke and vascular disease, which can lead to stroke. Ultrasound is also being used more and more to image the breasts and to guide biopsy of breast cancer.

What is Ultrasound Good at Imaging?

Because high-frequency sound waves cannot penetrate bone or air, they are especially useful in imaging soft tissues and fluid filled spaces. Ultrasound is good at non-invasively imaging of soft tissue organs without x-rays:
