When you hear the term “ultrasound,” you might immediately think of pregnancy scans, which use high-frequency sound waves, not radiation, to create images of the developing baby. However, ultrasounds have far broader applications in medicine.

For athletes and sports enthusiasts, they’ve become a pivotal tool in diagnosing and managing injuries, according to Michael Swartzon, M.D., primary care sports medicine physician with Baptist Health Orthopedic Care.

“Generally, when patients think about getting an ultrasound, it’s for obstetrics to look at babies,” said Dr. Swartzon, who illustrates the benefits of ultrasounds in a Baptist Health Instagram reel. “But in sports medicine, ultrasound has become my new stethoscope.”

What is an Ultrasound?

Ultrasound imaging, also known as sonography, is a diagnostic tool that uses high-frequency sound waves to create images of structures inside the body. Unlike X-rays, ultrasounds do not rely on radiation. Instead, a small device called a transducer sends sound waves into the body, which bounce back to form detailed images on a screen.

These images show variations in different types of tissues, including muscles, ligaments, tendons, and joints. Importantly, ultrasounds allow healthcare providers to assess injuries dynamically—meaning they can observe tissues as they move, which can provide insights into how the injury is affecting function.

“The ultrasound uses sound beams, so there’s no radiation,” said Dr. Swartzon. “We can see on the screen the difference between the subcutaneous skin and then the next layer.”

Ultrasounds provide real-time dynamic imaging where the tendons, muscles and joints move as the patient moves.  “If a patient points to an area, we can look at that specific spot directly under ultrasound,” explains Dr. Swartzon. “The patient can guide us to diagnosing the problem. This is something that MRIs and X-rays cannot do.”

Dr. Swartzon emphasizes that ultrasounds are safe for patients of all ages, and even for pregnant patients.

He adds that ultrasounds represent “faster and more accurate diagnoses leading to the best treatment decisions in one office visit.”  Patients avoid waiting for days for results or having to schedule an MRI, he adds.

How Ultrasounds Help Diagnose Sports Injuries

Sports injuries often involve soft tissues, including muscles, tendons, and ligaments. Ultrasound is particularly well-suited to detect issues in these structures because it provides real-time, high-resolution imaging. This makes it easier to pinpoint the exact location and extent of an injury—crucial information for creating an effective treatment plan.

“These ultrasounds are used to check for injuries, tears in the muscle, swellings. It’s a very easy tool we can use,” says Dr. Swartzon.

One of the standout benefits of ultrasound is its ability to visualize layers of tissue in extraordinary detail.

“You can see the quad tendon, you can see the patella and the bone right there on the right, and then you can go down and see if there’s any swelling or issues in the knee,” explains Dr. Swartzon in the Instagram reel. “Below that, you can see the femur. It’s a good way to evaluate the tissue.”

For an athlete dealing with knee pain, an ultrasound can quickly reveal whether the issue lies in the patellar tendon, the quadriceps tendon, or deeper structures like the ligaments or bone. This not only speeds up the diagnostic process but also reduces the need for more invasive tests or procedures.

The Benefits of Ultrasounds in Sports Medicine

Ultrasounds have earned their place in sports medicine for several reasons beyond diagnosis. Here’s a closer look at the key benefits:

1. Non-Invasive and Radiation-Free

Since ultrasounds do not use radiation, they are completely safe—even for repeated use. This is especially important for active patients who may require ongoing monitoring of a chronic condition or prolonged recovery from an injury.

2. Real-Time Imaging

Unlike an MRI or CT scan, which captures static images, ultrasounds allow for real-time movement evaluation. This is invaluable when assessing sports injuries, as a physician can ask the patient to move or contract a muscle while observing how the tissues respond. For example, this can help identify impingements, partial tears, or other functional issues that may not show up on a static image.

3. Guiding Treatment

Ultrasounds are not only diagnostic tools but can also enhance treatment. Dr. Swartzon offers an example of how this plays out in practice when treating joint injuries. He explains, “It’s also a great way to guide an injection into the knee, to make it safer, less painful, and more effective.” By visualizing the needle’s placement in real-time, physicians can ensure that medications like corticosteroids or platelet-rich plasma are delivered precisely where they’re needed, minimizing discomfort and maximizing the benefits.

4. Quick and Accessible

Ultrasounds can often be performed in a doctor’s office, eliminating the need for scheduling a separate imaging appointment. This convenience is especially appreciated by athletes eager to return to their sport as quickly as possible.

5. Cost-Effective

Compared to other imaging modalities like MRI or CT scans, ultrasounds tend to be more affordable. This makes them an excellent first-line diagnostic option, particularly for common sports injuries like strains, sprains, and tendonitis.

Common Sports Injuries Assessed with Ultrasound

Ultrasound imaging is versatile and can evaluate a range of sports-related injuries, including:

• Muscle Strains: Ultrasound can detect muscle tears, determine their severity, and monitor healing progress.
• Tendon Injuries: Tendonitis or small tears in tendons like the Achilles can be identified early to prevent more severe damage.
• Ligament Sprains: For example, ultrasound can help assess the extent of ligament injury in an ankle sprain.
• Joint Problems: Swelling, fluid buildup, or cartilage damage in joints like the shoulder, knee, or elbow can all be evaluated.

Why Athletes Should Consider Ultrasounds

Beyond its technical benefits, ultrasound imaging supports a proactive approach to healthcare. For athletes, early and accurate diagnosis of an injury can mean the difference between a short recovery and a prolonged absence from their sport. With ultrasound, physicians can detect subtle issues before they escalate into major problems, making it an essential tool for maintaining peak performance.

Dr. Swartzon sums it up best by calling ultrasound his “new stethoscope” in sports medicine. This small but powerful device is revolutionizing how injuries are diagnosed and treated, offering athletes a safer, faster, and more effective path to recovery.
