Sonography, also called diagnostic medical ultrasound, is one of the most widely used tools in modern healthcare. It’s non-invasive, safe, and provides real-time imaging that helps providers evaluate internal organs, tissues, and blood flow. But what exactly is sonography, and how does it work?
At TrueView Ultrasound in Roseville, we specialize in advanced sonographic imaging across a wide range of applications—from fetal imaging to abdominal, thyroid, vascular, and soft tissue evaluations. Whether you’re pregnant, managing a health condition, or just exploring options for preventive care, understanding this powerful tool can help you feel more confident during your next visit.
What Is Sonography?
A Definition of the Technology
Sonography uses high-frequency sound waves to create images of structures inside the body. These sound waves are emitted through a handheld device called a transducer. The waves travel into the body and bounce back when they hit internal organs or tissues. The echoes are then converted into images that appear in real time on a monitor.
Unlike X-rays or CT scans, ultrasound imaging does not involve radiation. This makes it a preferred option for prenatal exams and repeated scans. The ultrasound screenings available at TrueView include both diagnostic and preventative procedures to help you stay on top of your health.
What Can Sonography Detect?
Key Medical Uses
Sonography is extremely versatile. It’s commonly used to:
- Monitor pregnancy and fetal development
- Evaluate abdominal pain and organ function
- Check for gallstones, kidney stones, or liver disease
- Assess thyroid nodules or gland enlargement
- Detect vascular blockages or blood clots
- Guide minimally invasive procedures like biopsies
Because sonography shows movement and flow, it’s also valuable in measuring heartbeat, assessing blood flow, and detecting internal fluid buildup.
How Does the Procedure Work?
Step-by-Step Breakdown
During your sonogram, you’ll lie comfortably while a technician applies a special gel to the area being scanned. The gel removes air between the skin and transducer, allowing sound waves to travel more efficiently. The technician then glides the transducer across the skin, capturing images for the physician to review.
Most scans take 20 to 45 minutes, depending on the area of the body. At TrueView, our certified sonographers ensure every image is captured with precision and care. To help prepare, patients can follow our ultrasound preparation guide based on the type of exam.
Why Is Sonography So Widely Used?
Safety, Speed, and Accuracy
Sonography offers several advantages. It’s non-invasive, requires no incisions, and involves no radiation exposure. The results are available quickly, and the images are often used to diagnose or rule out conditions without needing more invasive procedures.
Additionally, sonography is safe for all ages, including unborn babies. It’s a key reason why expecting families often choose TrueView for their prenatal and diagnostic needs. Patients can reach out through our contact page to schedule a scan or ask questions about eligibility.
