What is an ultrasound?
An ultrasound scan may image the inside of the body using sound waves to produce a real-time picture. Usually, ultrasound is painless and non-invasive. Ultrasound works differently from X-rays because it does not use radiation.
An ultrasound scan involves a transducer directing high-frequency sound waves at the region of the body under investigation. The transducer senses the reflected sound waves (echoes) and creates a picture on a monitor.
What are the types of ultrasound scans?
Common types of ultrasound scan include:
- Abdominal ultrasound: This test looks at the liver, gallbladder, pancreas, and spleen, among other internal organs.
- Obstetric/pregnancy ultrasound: This is a routinely used tool to monitor the growth and health of unborn babies during pregnancy.
- Female pelvis ultrasound: Female pelvic ultrasonography is used to examine the female pelvis, uterus, cervix, fallopian tubes, and ovaries.
- Ultrasound of the breasts: To examining breast symptoms like lumps, breast ultrasonography is used to screen for breast cancer in women with dense breast tissue. Renal ultrasonography, which examines the kidneys and bladder as well as the urinary tract.
- Transrectal ultrasound: Transrectal ultrasound, which examines the prostate gland.
Why an ultrasound is performed?
Other forms of ultrasounds include:
- Doppler ultrasound: this evaluates blood flow in main arteries and veins
- Echocardiogram, a test that examines the heart
- 3D ultrasound-that which produces a three-dimensional picture of the inside of the body
- 4D ultrasound, which produces a 3 dimensional picture in motion
How do I prepare for an ultrasound?
Preparations depend on the type of ultrasound you’re having. Some types require no preparation at all.
Some ultrasound scans of the pelvis, like pregnancy ultrasound, female reproductive system ultrasound, and urinary system ultrasound, may ask you to drink water ahead of time and fill your bladder.
To prepare for some abdominal ultrasounds, you may need to modify your diet or fast, not eat or drink for several hours beforehand.
In any case, your healthcare provider will advise you if there is anything special you need to do in preparation for your ultrasound. They may brief you during a visit or when they schedule your ultrasound. Your instructions might be there if you have an electronic medical record system.
How does an ultrasound work?
You will be asked to undress and wear a gown before the test. Then, you will likely lie on a table with part of your body uncovered.
A sonographer or ultrasound technician will rub your skin with a special lubricating jelly to prevent friction so they can rub the ultrasound transducer on your skin. The transducer is small and hard-looking, somewhat like a microphone. The jelly also helps to conduct sound waves.
The transducer emits high-frequency sound waves through your body. The waves echo when they hit an object of substance, such as an organ or bone. Those echoes reflect into a computer. The sound waves occur at a pitch that is too high for the human ear to hear. They create an image that the doctor can understand.
You may be required to change positions during the exam for the technician to get better access to the area being tested.
After the test is completed, the gel will be cleaned off your skin. Depending on the area being tested, the entire procedure usually takes less than 30 minutes. You can resume normal activities once the test has been completed.
What happens during an ultrasound?
Preparation for an ultrasound varies depending on which part of your body you will be having scanned. Your clinician may ask you to take off some clothing and wear an examination gown.
Ultrasounds in which the transducer (probe) is placed over your skin and not inserted into your body, as with an endoscopic ultrasound, typically proceed as follows:
- You will be positioned on your side or back on a comfortable table.
- With the use of a small amount of water-soluble gel on your skin over the area being examined, the ultrasound technician will begin the procedure. The gel does not harm your skin and will not discolor your clothes.
- Images are acquired when the technician moves a handheld transducer, or probe, over the gel inside your body.
- They may ask you to remain perfectly still or to hold your breath for a few seconds when taking better images.
- Once the technician feels that enough images have been taken, they will remove the remaining gel from your skin and you will be done.
An ultrasound typically takes 30 minutes to an hour. If you have any questions about your type of ultrasound, you should ask your healthcare provider.
What are the limitations of ultrasound?
Ultrasound is limited in its use for imaging bones and air-filled tissues, such as the lungs. Individuals with overweight and obesity may receive less clear images using ultrasound, as the sound waves have to travel through more tissue.
Are there any risks with ultrasound?
As it does not utilize radiation, ultrasound is extremely safe and can be used routinely in pregnancy.
However, These sounds, which the ultrasound probe gives out, are beyond the threshold of human hearing; hence, you will not hear them.
Is an ultrasound painful?
Ultrasounds over your skin (outside of your body) do not typically hurt. You will not feel the sound waves that ultrasound uses. You may feel discomfort if you drink a lot of water to fill your bladder before the test. Or you may feel some discomfort while lying on the exam table if you are pregnant.
Ultrasounds that enter the body cavities, such as your vagina or rectum, may be somewhat uncomfortable, but it should not hurt.
What do the results mean?
Results of an ultrasound depend on the type of ultrasound you had. Your provider can tell you what your results mean for your health.
If you had a pregnancy ultrasound, normal results mean your baby appears to be developing normally. But an ultrasound can’t guarantee that you’ll have a normal, healthy baby. You may need further tests, including another ultrasound exam, if your test results are abnormal.
