What Is an Ultrasound?
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.
What to Expect During Your Exam
Your ultrasound is straightforward, comfortable, and typically completed in 30 minutes or less.
1
Get Comfortable
You’ll be positioned on an exam table — typically on your back or side, depending on the study.
2
Gel Applied
A warm, water-soluble gel is applied to the area being scanned to help the sound waves travel.
3
Imaging Begins
The sonographer moves a transducer (handheld probe) across your skin, capturing real-time images.
4
Stay Still or Hold Breath
You may be asked to hold your breath briefly or remain very still to capture clear images.
5
All Done
The gel is wiped off, you can resume normal activities immediately. No recovery needed.

- Splenic Enlargement
- Abdominal Aortic Aneurysm
- Hydronephrosis
- Organ Cysts or Tumors
Arterial Ultrasound
Peripheral arterial disease affects millions of adults, particularly those over 50 with risk factors like diabetes or tobacco use. Our arterial ultrasound evaluates blood flow through the upper and lower extremities to detect plaque buildup, narrowing, or blockages before they progress to serious complications. The exam is completely noninvasive and typically completed within 30 minutes.

Carotid Ultrasound
Carotid ultrasound is the primary screening tool for evaluating the arteries that supply blood to the brain. Given that cardiovascular disease and stroke remain among the top causes of death in the U.S., early detection of arterial narrowing is critical. This quick, in-office exam takes roughly 30 minutes and is recommended for patients with key risk factors such as high blood pressure, elevated cholesterol, or a family history of vascular disease.
Common Indications
- Episodes of Slurred Speech
- Temporary Vision Loss
- Unexplained Dizziness or Vertigo
- Loss of Coordination
- Fainting or Near-Fainting

- Arterial Wall Thickening
- Risk of Transient Ischemic Attack
- Stroke Risk Assessment
- Compromised Cerebral Blood Flow
- Subclavian Artery Stenosis
Echocardiogram Ultrasound
An echocardiogram uses ultrasound technology to produce a moving picture of the heart, allowing physicians to evaluate how effectively it beats, pumps blood, and manages flow through its chambers and valves. This examination is essential for diagnosing structural and functional cardiac conditions and plays a vital role in ongoing cardiovascular care.
Common Indications
- Chest Pain or Discomfort
- Persistent Shortness of Breath
- Severe or Resistant Hypertension
- Heart Murmur Detection

- Overall Cardiac Function
Pelvic Ultrasound
Pelvic ultrasound offers a safe and reliable method for evaluating the reproductive and urinary organs, including the uterus, ovaries, fallopian tubes, cervix, and bladder. Using Doppler technology to assess blood flow patterns, this 30-minute exam provides critical diagnostic information. A full bladder is typically recommended for optimal imaging.
Common Indications
- Pelvic Pain or Pressure
- Suspected Fibroids
- Abnormal or Irregular Bleeding
- Missed or Absent Menstrual Periods
- Pelvic Inflammatory Concerns
- Endometrial Thickening
- Urinary Tract Obstruction
- Post-Menopausal Bleeding

Renal Ultrasound
A renal ultrasound provides a thorough, noninvasive assessment of the kidneys, ureters, and bladder. Using real-time imaging enhanced by color Doppler, this exam identifies structural abnormalities, fluid blockages, stones, and masses within the urinary system. No special preparation is needed, and results are typically available in under 30 minutes.
Common Indications
- Flank or Lower Back Pain
- Blood in the Urine
- Suspected Kidney Stones
- Elevated Protein in Urine
- Swelling of the Kidneys
- Recurrent Bladder Infections
- Kidney Infection Symptoms
Diagnostic Findings

Scrotal Ultrasound
Scrotal ultrasound is widely regarded as the definitive imaging method for evaluating testicular health. This 30-minute examination provides high-resolution, real-time images of the testicles, epididymis, spermatic cord, and surrounding structures while simultaneously monitoring arterial and venous blood flow to detect a broad range of conditions.
Common Indications
- Testicular Pain or Swelling
- Palpable Scrotal Mass

Billing & Insurance
Common questions about how your ultrasound is billed.
Will my insurance cover this exam?
Viason bills Medicare, Medicaid, and most major commercial insurance plans. Coverage and out-of-pocket costs vary by plan and exam type. Our billing team can verify your benefits before your appointment — call 800-536-0077 with questions.
Will I receive a separate bill from Viason?
Yes. You may receive a bill from Viason for the technical component of your ultrasound, and a separate bill from the radiologist who interpreted your study. Both are submitted to your insurance.
Why is on-site ultrasound more affordable?
