Ultrasound Gel: Know Its Types and How To Use

Ultrasonography (USG) hand holding ultrasound probe and coupling gel prepare for diagnostic.
Ultrasound gel is an essential component of ultrasound imaging procedures. This specialized gel gets applied to the skin before an ultrasound scan to improve the ultrasound machine's image quality. The gel helps to eliminate air pockets between the skin and the ultrasound probe, allowing for better conduction of sound waves and improved visualization of internal structures. While it may seem like a simple product, the type and quality of ultrasound gel used can significantly impact the accuracy and effectiveness of ultrasound imaging. This blog post will teach us about ultrasound gel.

Ultrasound Gel:

It is a specialized gel used in ultrasound imaging procedures. It is a conductive medium applied to the skin before an ultrasound scan to help the ultrasound probe make better contact with the skin. The gel eliminates air pockets between the skin and the probe, which can interfere with the transmission of sound waves and reduce image quality. The composition varies, but it is typically water-based and contains various ingredients that help improve conductivity and reduce the risk of skin irritation. Different gels are available; the selection depends on the specific application and the patient's needs.

Ultrasound Imaging:

Ultrasound gel plays a critical role in ultrasound imaging, as it helps to improve the accuracy and clarity of the images produced by the ultrasound machine. Without gel, obtaining high-quality images of internal structures would be challenging, as air pockets between the skin and the probe can cause interference and reduce the effectiveness of the ultrasound waves.

During an ultrasound procedure, the ultrasound gel is applied to the patient's skin in the area to be examined. The ultrasound probe is then placed on the skin and moved over the area of interest, transmitting high-frequency sound waves through the gel and into the body. The gel helps to ensure that the ultrasound waves can penetrate the skin and reach the internal structures without being reflected or absorbed by air pockets.

It also helps to reduce friction between the skin and the probe, making it easier to move the probe around and obtain clear images. It is especially important in areas with a lot of hair or oil on the skin, as these can interfere with the transmission of ultrasound waves.

Ultrasound gel helps make the ultrasound procedure more comfortable for the patient. The gel is typically cool and soothing, which can help to reduce discomfort and make the procedure more tolerable.

Types Of Ultrasound Gel::

Various gels are available in the market, each with unique features and benefits. The appropriate selection depends on the specific application and the patient's needs.

Standard: This is the most common type of ultrasound gel suitable for most imaging applications. It is typically water-based, odorless, and non-staining. Standard ultrasound gel is also hypoallergenic and does not cause skin irritation or damage to the ultrasound probe.

Sterile: It gets used in sterile environments, such as during surgical procedures. It is free from bacteria and other contaminants and is packaged in a sterile container to prevent contamination.

Non-greasy: Non-greasy ultrasound gel provides better skin adhesion without leaving a greasy residue. It is ideal for use in areas with a lot of hair or oil on the skin, as it helps reduce friction and improve image quality.

Warm: Warm gel provides a comfortable patient experience, as it gets heated to body temperature before application. The warm gel helps to relax the muscles and reduce discomfort during the procedure.

Eco-Friendly: Eco-friendly ultrasound gel is more environmentally friendly than traditional ultrasound gel. It is typically made from natural ingredients and is free from harmful chemicals, making it safer for patients and the environment.

Conductive: Conductive ultrasound gel improves the conduction of ultrasound waves through the skin. It contains special conductive particles that help improve sound wave transmission and reduce interference.

Aquasonic: Aquasonic ultrasound gel is a popular brand of ultrasound gel known for its superior quality and effectiveness. It is suitable for various imaging applications and is available in various sizes and formulations.

Overall, selecting the appropriate type depends on the specific application and the patient's needs.

How To Use:

Using ultrasound gel is straightforward, and following the proper procedures to ensure optimal image quality and patient comfort is essential.

Prepare the patient: Before applying ultrasound gel, it is necessary to prepare the patient. The area should be clean and dry, and the patient should be positioned correctly for the procedure.

Apply the gel: Apply a generous amount to the skin in the area to be examined. Spread the gel evenly over the skin, and the thickness of the gel layer should be uniform.

Position the ultrasound probe: Once the gel is applied, position the probe over the area to be examined. The probe should be pressed firmly against the skin to ensure good contact with the gel.

Begin the examination: Begin the examination by moving the probe over the area of interest. The gel can be reapplied as needed to maintain good contact with the skin.

Clean up: Once the examination is complete, clean up any excess gel from the skin and the probe. Use a clean cloth or paper towel to remove the gel, and discard it according to local regulations.

Use the appropriate type of ultrasound gel for the specific application, and medical professionals should follow the manufacturer's instructions. Using too little gel can result in poor image quality, while using too much can cause the gel to pool and interfere with the ultrasound waves.


It is generally considered safe for use in medical imaging procedures. However, follow proper safety precautions to ensure patient and user safety.

The gel should be stored in a cool, dry place and not used past its expiration date. Use the appropriate gel type for the specific procedure and follow the manufacturer's instructions.

Medical professionals should be aware of any potential allergies or sensitivities that patients may have to the gel and should take appropriate measures to prevent adverse reactions.

Following proper safety procedures, medical professionals can safely use them to provide accurate and effective medical imaging services.


In conclusion, ultrasound gel is an essential component of ultrasound imaging, providing conductivity for ultrasound waves to pass through the body and produce high-quality images. Different types of ultrasound gel are available, each designed for specific applications, and it is important to use the appropriate gel for each procedure. It ensures patient comfort, safety, and image quality. Medical professionals should continue to follow proper safety procedures and techniques when using ultrasound gel to ensure the best possible outcomes for their patients.
