Most people have heard of ultrasound and associate this common imaging procedure with pregnancy. What many people don’t realize is that ultrasounds can be used to detect a wide variety of medical issues - in fact, ultrasound is one of the most diverse imaging procedures available and can be used in a number of situations outside of pregnancy.
Today we’re taking some time to educate the public about this incredible technology by answering some of the most frequently asked questions about ultrasound that we’ve heard during our decades of practice.
How Do Ultrasounds Work?
One of the most common initial questions we get from patients is “What is an ultrasound?” Before we can really dive into the benefits of ultrasound technology, patients first have to understand how the procedure even works.
An ultrasound (also sometimes referred to as a sonogram) is an incredibly versatile imaging technique that uses high-frequency sound waves to produce images of the body’s internal organs. The procedure is designed to detect medical issues and check on the status of developing fetuses.
Ultrasounds are painless and do not expose the patient to any radiation, so there’s no risk associated with the procedure. During an ultrasound, the specialist smooths a wand (transducer) over the area to produce images on a computer screen. In some cases, a special wand must be inserted into the vagina, rectum, or esophagus to get pictures.
How Long Does An Ultrasound Take?
Most ultrasounds take approximately 30 minutes or less, depending on the areas examined. If detailed work is needed, the exam could take longer! Be sure to check with your doctor before the appointment to plan accordingly.
What Is An Ultrasound Used For?
Ultrasounds are useful for detecting kidney stones, fibroids and other uterine issues, breast cancer, and for determining the sex of an unborn fetus. Doctors use them to search soft tissue for hard masses (rather than liquid-filled cysts) to detect cancer, and ultrasound technology can also be used to guide the insertion of a needle or catheter placement.
What An Ultrasound Cannot Detect
Although ultrasounds are a great way to identify medical issues early before they become life-threatening, like any imaging procedure they do have some limitations. Ultrasounds can be used to detect small masses, but cannot show whether or not they are cancerous. Additionally, the technology isn’t the strongest imaging option available for patients who have potential issues within their lungs or related to their bones.
What Types Of Ultrasounds Are There?
There are a few different types of ultrasounds: 2-D, 3-D, 4-D, and Doppler. 2-D ultrasounds are used most often with pregnancy and are very effective. However, 3-D and 4-D ultrasounds provide much greater detail, which in some cases is needed. 4-D ultrasounds can also be used to produce video rather than just a still image, enabling physicians to see things they might otherwise miss. Doppler ultrasounds are less common, but unique in the sense that they can show the speed of a patient’s blood flow to help detect tumors.
