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.
What to expect
Ultrasound is a safe procedure which uses no radiation
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 trans-vaginal 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.
The day of the Ultrasound
Creating an ultrasound requires three processes: producing the sound wave, receiving echoes from it, and then interpreting those echoes.
Each modality images differently. Sometimes it is necessary to image with different modalities for the best diagnosis. An ultrasound is what your doctor has referred you for at this time. If additional imaging is needed, the radiologist will recommend it.
