Referred for an Ultrasound? What's Involved?
When you've been suffering from some unusual but persistent pains and the doctor has not been able to identify the cause quickly, they may recommend that you go for an ultrasound examination. If you've never done this before and do not know what's involved, you may be curious about the process or maybe a little nervous as well. So what exactly is an ultrasound, and how does it work?
Sound Wave Technology
In essence, ultrasound technology will use high-frequency sound waves that bounce back and forth between the device and your internal organs. Due to some very clever software, a program will then recreate an image of the inside of your body, and an expert can use this imagery to diagnose any issues.
Creating an Image
To conduct the examination, a technician will hold a probe (known as a transducer) on your skin's surface, which will transmit sound waves into the body. These waves will echo back when they encounter soft tissue and bones, and this will allow the program to build up layers and create the final image. The technology will be able to interpret the speed at which the sound waves travel as well as the direction and distance covered to create a remarkably accurate, two-dimensional image.
Abdominal Examination
Doctors may often recommend an ultrasound to check for problems within the abdomen. For example, they'll be on the lookout for liver issues, gallstones or kidney stones and can determine if there is any issue by looking at the texture of the organ and corresponding blood flow. This kind of examination will also show any tumours and will be able to differentiate between something that is benign and malignant.
The Procedure
In some circumstances, you may be asked to fast before you visit, but your doctor will confirm the arrangements in advance. When you get to the facility, the technician will typically spread a gel substance onto the skin's surface as this helps the sound waves pass through more efficiently. While the procedure may take some time to complete, it is totally painless and not uncomfortable at all. Then, when the examination is complete, the technician may send the results directly to your doctor or as otherwise arranged in advance.
Question Time
If you have any other questions, you can always ask your family doctor. Otherwise, don't be afraid to ask the technician to help explain the ultrasound procedure.
