Everything you need to know about Ultrasound

How Ultrasound scans work

Ultrasound uses soundwaves to produce images of structures inside the body. These images can detect a variety of diseases and conditions. It doesn’t use any radiation and is generally pain-free. Often associated with pregnancy scans, Ultrasound has many other uses.
An Ultrasound scan can be used to examine most parts of the body, including:

What to expect

Ultrasound is a safe procedure, requiring no radiation or needles.
You’ll sit or lie beside the machine which looks like a TV screen with leads. Water soluble gel is applied, then a handheld transducer is placed on your skin with mild pressure and moved around. Sometimes ultrasounds are done internally such as transvaginal pelvic scans – the sonographer will explain the procedure and obtain consent prior to the examination. Once the scan is complete, you’re free to leave.

Patient stories

Creating an ultrasound requires three processes: producing the sound wave, receiving echoes from it, and then interpreting those echoes.


Ultrasound uses sound waves, and no ionizing radiation, and has no known significant risks.
The ultrasound scan itself should not cause you much pain, if any, and is generally non-invasive, so you don’t need any recovery time. Most people can go about their normal business once they have finished the ultrasound examination.
A full bladder pushes the uterus in a position where we can see it better, and brightens up the entire pelvis so that we can adequately visualize the uterus and ovaries. It also moves the intestines and bowel out of the way.
Each modality images differently. Sometimes it is necessary to image with different modalities different ways for the best diagnosis. An ultrasound is what your doctor’s office has ordered at this time. Ultrasound is a very good, and very safe test. If additional imaging is needed, the radiologist will recommend it.
