What are the most common reasons why patients visit for Ultrasound?
Your doctor may order an ultrasound if you’re having pain, swelling, or other symptoms that require an internal view of your organs. An ultrasound can provide a view of the:
- brain (in infants)
- blood vessels
An ultrasound is also a helpful way to guide surgeons’ movements during certain medical procedures, such as biopsies.
How an Ultrasound is performed ?
Before the exam, you will change into a hospital gown. You will most likely be lying down on a table with a section of your body exposed for the test.
An ultrasound technician, called a sonographer, will apply a special lubricating jelly to your skin. This prevents friction so they can rub the ultrasound transducer on your skin. The transducer has a similar appearance to a microphone. The jelly also helps transmit the sound waves.
The transducer sends high-frequency sound waves through your body. The waves echo as they hit a dense object, such as an organ or bone. Those echoes are then reflected back into a computer. The sound waves are at too high of a pitch for the human ear to hear. They form a picture that can be interpreted by the doctor.
After the procedure, the gel will be cleaned off of your skin. The whole procedure typically lasts less than 30 minutes, depending on the area being examined. You will be free to go about your normal activities after the procedure has finished.
