An ultrasound is a safe, painless, non-invasive diagnostic exam that uses high-frequency sound waves — not radiation — to produce real-time images of soft tissues, blood vessels, and organs inside the body. Sound waves are reflected by tissue and converted into images by a sophisticated computer system, allowing your physician to evaluate your health without any incisions or injections.
Because ultrasound uses sound rather than radiation, it is considered one of the safest imaging modalities available — appropriate for patients of all ages, including pregnant women.
Your ultrasound is straightforward, comfortable, and typically completed in 30 minutes or less.
You’ll be positioned on an exam table — typically on your back or side, depending on the study.
A warm, water-soluble gel is applied to the area being scanned to help the sound waves travel.
The sonographer moves a transducer (handheld probe) across your skin, capturing real-time images.
You may be asked to hold your breath briefly or remain very still to capture clear images.
The gel is wiped off, you can resume normal activities immediately. No recovery needed.

Your study is performed and interpreted entirely by credentialed professionals.
Every Viason sonographer is nationally credentialed by ARDMS or CCI in cardiac, vascular, general, or OB/GYN sonography — the highest professional standard in the field.
Your images are interpreted by a board-certified radiologist or specialty physician who issues the final report sent directly to your referring provider.
Your physician will review the final report with you and discuss next steps. Sonographers are not permitted to share findings — that comes from your doctor.
Same-day preliminary findings are provided to your referring physician so urgent concerns can be acted on immediately.
Final radiologist report is delivered to your physician within 24–48 hours of your exam.
Please note: ultrasound sonographers are not permitted to interpret or discuss findings during your exam. All results must come directly from your physician after they have reviewed the final report.
All Viason ultrasound exams are performed inside your physician’s office. There’s no need to travel to a separate imaging center, hospital, or specialty facility — we bring everything to your doctor.
A few simple steps help us deliver the most accurate exam possible.
Continue taking all prescribed medications unless your physician tells you otherwise.
Allow time to check in and complete any necessary paperwork before your scheduled time.
Loose-fitting clothing is best. You may be asked to change into a gown for some exams.
Coordinate with your physician about meal and insulin timing if your exam requires fasting.
Have your insurance card and photo ID ready at check-in.
Some exams require fasting or a full bladder — see the table below for your specific exam.
