A kidney arterial ultrasound evaluates blood flow through the renal arteries. Narrowing of these arteries is a common and often missed cause of treatment-resistant high blood pressure and declining kidney function.
You don't need a doctor's referral. This scan is strongly recommended if any of the following apply to you:

Many people have never had this scan before. Here is exactly what happens — no surprises, no anxiety.
No radiation. No needles. No discomfort. An ultrasound uses sound waves — the same technology used in obstetric imaging. It is entirely safe and non-invasive.
We ask that you avoid eating for 4–6 hours before this scan for the clearest possible images of the kidney arteries.
Gel is applied to your upper abdomen. The sonographer uses a probe to locate and image both renal arteries.
Flow velocities are measured at the origin of each renal artery and along its length to detect any significant narrowing.
We also evaluate kidney size and appearance — chronic narrowing often causes one kidney to shrink over time.
Findings include flow velocity ratios, degree of stenosis if present, kidney size comparison, and clinical interpretation.
These conditions often develop without symptoms for years. Early detection changes the outcome dramatically.
Narrowing of the arteries supplying the kidneys — a correctable cause of difficult-to-control hypertension.
Decreased blood flow to one or both kidneys accelerating kidney function decline.
A smaller kidney on one side often indicates chronic reduced blood flow on that side.
A non-atherosclerotic arterial condition commonly affecting renal arteries — especially in younger women.
Rare but important finding — abnormal widening of the renal artery requiring monitoring or treatment.
For patients who have previously had renal artery stenting, this scan monitors for restenosis.
We built BlackPoint Diagnostics because quality cardiovascular imaging shouldn't require a hospital visit, a referral, or a weeks-long wait. Our sonographer performs cardiovascular imaging daily alongside physicians — this is clinical-grade diagnostics delivered with genuine convenience.
