If your doctor has recommended an ultrasound, you may have a lot of questions about what to expect. From how the procedure works to whether it’s safe and what it can detect, understanding the basics can help ease any worries. Ultrasounds are a commonly used imaging technique in medicine, providing a safe and painless method for examining the body’s internal structures. Let’s explore some of the common questions people have about ultrasounds, also known as sonography, and what you need to know before your appointment.
How Does an Ultrasound Work?
An ultrasound machine uses high-frequency sound waves to create images of your internal body structures. The technician places a device called a transducer on your skin, which sends sound waves into your body. These sound waves bounce off your organs, tissues, and other structures inside you.
The transducer picks up the returning sound waves and sends this information to a computer. The computer translates these sound waves into moving pictures that appear on a screen. This process occurs in real-time, allowing doctors to see your organs in motion as the scan takes place.
The sound waves used in ultrasounds are much higher in frequency than what humans can hear. They travel through your body safely and do not cause any known harmful effects. This makes sonography a safe medical imaging method.
Why Might I Need One?
Doctors recommend ultrasound scans for many different reasons. During pregnancy, sonography helps monitor your baby’s growth and development. Your doctor uses this medical imaging to check your baby’s position, measure growth, and look at the baby’s organs.
For gynecologic care, doctors use sonography to examine your reproductive organs. They might recommend a sonogram to find the cause of pelvic pain or unusual bleeding. Ultrasounds also help doctors look for conditions like ovarian cysts or uterine growths.
Doctors also use ultrasound imaging to examine other parts of your body. They may need to examine your gallbladder, liver, kidneys, or heart. Sonography helps doctors visualize blood flow through your vessels and detect blockages or other abnormalities.
What Should I Expect During the Procedure?
The ultrasound procedure is straightforward and comfortable for most patients. You will lie on an exam table while the technician performs the scan. The room is usually dimly lit so that the technician can see the images on the screen clearly.
Before starting, the technician applies a clear gel to your skin where the transducer will be placed. This gel helps the sound waves travel better between the transducer and your body. The technician then moves the transducer across your skin while watching the images on the monitor. You may feel gentle pressure as the technician presses the transducer against your skin to obtain clearer images.
Are There Different Types?
Medical facilities offer several types of sonography depending on what your doctor needs to examine. Transabdominal ultrasounds are a common type, where the technician places the transducer on your abdomen to get images of your internal organs.
Transvaginal ultrasounds provide clearer pictures of your reproductive organs. During this type of sonogram, the technician uses a special transducer that goes inside your vagina. This method often gives doctors better images of your uterus and ovaries than an abdominal ultrasound.
Some facilities also offer 3D ultrasounds, which create detailed images than regular sonography. These are often used during pregnancy to get clearer pictures of the baby. The 3D technology provides images that show more depth and detail than traditional 2D ultrasounds.
