Ever Wondered Why Gel Is Always Used During an Ultrasound? It Turns Out Its Function Is More Important Than Imagined
When undergoing an ultrasound examination, almost everyone has the same experience. The doctor or medical professional will apply a clear gel to the body area before placing the ultrasound device. Many people assume the gel only serves as a lubricant to make the device easier to move.
However, in reality, without ultrasonic gel, the results of an ultrasound examination can be less optimal and even difficult to produce clear images.
So, what exactly is the function of ultrasonic gel? And in what conditions is this gel needed?
What is Ultrasonic Gel?
Ultrasonic gel or USG gel is a water-based gel used as a medium to transmit ultrasonic waves from the transducer (ultrasound probe) to the patient's body.
This gel is designed with special properties to eliminate the air layer between the skin surface and the ultrasound probe.
Why is it necessary to eliminate air?
Because air is the main enemy of ultrasound examinations. Ultrasonic waves find it very difficult to penetrate air, so if the probe is placed directly on the skin without gel, most of the waves will be reflected back. As a result, the image produced will be less clear or even unreadable.
With ultrasonic gel, sound waves can be transmitted optimally, resulting in more accurate imaging.
Why is Ultrasonic Gel So Important?
Many people think that the quality of the ultrasound machine alone is sufficient to determine the examination results.
In fact, the quality of the transmission medium also plays a big role.
The use of ultrasonic gel helps to:
-
Reduce resistance between the probe and the skin.
-
Produce sharper and more detailed images.
-
Reduce noise or interference in the imaging results.
-
Help the probe move more smoothly during the examination.
-
Improve patient comfort during the ultrasound process.
That is why almost all hospitals, clinics, laboratories, and doctor's offices use ultrasonic gel as standard equipment in every ultrasound examination.
What Conditions Require Ultrasonic Gel?
Ultrasonic gel is not only used during pregnancy examinations. Its use is much wider in the medical world.
1. Pregnancy Examination (Obstetrics)
This is the most well-known use to the public.
The gel is used when doctors monitor fetal development, baby's position, amount of amniotic fluid, and fetal heart rate to ensure clearer images.
2. Gynecological Examination (Gynecology)
Gynecologists use ultrasonic gel to assist in examining female reproductive organs, such as the uterus and ovaries.
Clear imaging is very helpful in detecting various medical conditions early.
3. Heart Examination (Cardiology)
In echocardiography, ultrasonic gel helps sound waves penetrate body tissues so that doctors can see the heart's structure and function in more detail.
4. Blood Vessel Examination (Doppler)
Doppler ultrasound is used to view blood flow.
The gel helps produce a better signal so that the speed and direction of blood flow can be analyzed accurately.
5. Internal Organ Examination
Organs such as the liver, kidneys, pancreas, spleen, gallbladder, and bladder are also examined using ultrasound.
Without good gel, the quality of images of these organs can decrease.
6. Ultrasound Therapy
In addition to diagnosis, ultrasonic gel is also used in ultrasound therapy devices in medical rehabilitation clinics and physiotherapy.
The gel helps ultrasound energy be delivered optimally to body tissues, making therapy more effective.
7. Other Electromedical Examinations
Some specific electromedical devices, including some types of EEG examinations or other ultrasound-based devices, also require a conductive medium in the form of gel for optimal device readings.
Characteristics of Quality Ultrasonic Gel
Not all gels have the same quality. For medical use, it is best to choose a gel with the following characteristics:
-
Transparent so that the examination area remains easily visible.
-
Does not damage the surface of the ultrasound probe.
-
