A complete guide to your abdominal aortic aneurysm (AAA) screening — a simple, painless scan that checks the body's largest artery for dangerous widening.
Many patients have never had this type of scan before. Here is exactly what will happen — no surprises.
Completely painless and non-invasive. Ultrasound uses sound waves — no radiation, no needles, no discomfort. Most patients find the experience relaxing.
You will lie flat on an exam table with your abdomen exposed from the lower chest to the navel.
Ultrasound gel is applied to your upper abdomen. The gel ensures good contact between the probe and your skin.
The sonographer locates the aorta just below the xiphoid process (the tip of the breastbone) and traces it downward through the abdomen.
The aorta is measured at multiple levels in both the anteroposterior (front to back) and transverse (side to side) dimensions.
The iliac arteries — where the aorta divides at the pelvis — may also be evaluated as aneurysms can extend into these vessels.
Your cardiologist report will include precise measurements, classification (normal, ectatic, or aneurysmal), and recommended monitoring or follow-up intervals.
Your cardiologist report is written in plain language, but here are the specific measurements and terms you may encounter — and exactly what they mean.
The key measurement. Normal adult aorta: under 3.0 cm. Ectatic: 3.0–2.9 cm. Aneurysm: 3.0 cm or greater. Surgical threshold: typically 5.5 cm.
Small (3.0–4.4 cm): surveillance every 2–3 years. Medium (4.5–5.4 cm): surveillance every 6–12 months. Large (5.5 cm+): vascular surgery referral.
Clot material inside the aneurysm sac. Present in many AAAs. Does not change the diameter measurement but is documented for clinical context.
Whether the aneurysm is fusiform (uniform widening — most common) or saccular (localized outpouching — higher rupture risk).
Whether the aneurysm extends into the iliac arteries. Important for surgical planning and classification.
If bowel gas limited visualization, a repeat scan with additional fasting may be recommended to ensure complete assessment.
Your report will clearly state whether follow-up is needed and how urgently. Here is what each outcome typically means.
No significant abnormalities. Share your report with your primary care physician. Consider repeat screening in 1–3 years based on your risk profile.
Minor findings that warrant monitoring. Your report will specify follow-up timing and any lifestyle recommendations.
Clinically significant findings requiring physician review. Your report will indicate appropriate urgency.
Findings requiring prompt evaluation. We will contact you directly in addition to delivering your report.

You should fast for 8–12 hours before your AAA ultrasound to reduce bowel gas that can obstruct visualization. Wear loose, comfortable clothing with easy access to your abdomen. Continue taking all prescribed medications with small sips of water. The scan itself takes approximately 20–30 minutes and is completely painless.
At BlackPoint Diagnostics, a board-certified cardiologist reviews your images and delivers a written clinical report within 24–48 hours via secure email. The report includes precise diameter measurements, classification, and any recommended follow-up.
BlackPoint Diagnostics is a direct-pay service at $397 per scan, all-inclusive. No insurance pre-authorization is needed. HSA and FSA payments are accepted. Medicare covers a one-time AAA screening for eligible patients — check with your provider for details.
Yes. An AAA ultrasound is completely non-invasive — no sedation, no needles, no contrast dye. You can drive, return to work, and resume all normal activities immediately after the scan.
Your cardiologist report will clearly classify any findings and recommend appropriate follow-up intervals. Small aneurysms (3.0–4.4 cm) typically require surveillance every 2–3 years. Larger findings may require more frequent monitoring or vascular surgery referral. For significant findings, our team contacts you directly.
No referral needed. $397 all-inclusive. Results from a board-certified cardiologist within 24–48 hours.
