A lower extremity venous ultrasound screens for deep vein thrombosis and venous insufficiency — conditions that are common, often silent, and potentially life-threatening if a clot travels to the lungs.[1]
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.
No preparation required. You may be asked to lie in slightly different positions to get the best views of each vessel.
From the groin down to the calf, the sonographer compresses the vein at intervals to check for clots blocking normal flow.
Color Doppler shows the direction and speed of blood moving through each vein — identifying abnormalities in real time.
We check for venous insufficiency — leaking valves that cause blood to pool and flow backward, leading to swelling and discomfort.
Your report details any clots found, venous reflux findings, and recommended next steps.
These conditions often develop without symptoms for years. Early detection changes the outcome dramatically.
Blood clots in the deep veins of the leg. Can be life-threatening if they travel to the lungs as a pulmonary embolism.[2]
Leaking vein valves that cause blood to pool in the legs — a common cause of chronic swelling and aching.
Clotting in the superficial veins — less dangerous than DVT but requiring monitoring and management.
Detailed mapping of incompetent vein segments that are candidates for treatment.
Chronic vein damage from previous clots — identified by scarring and abnormal flow patterns.
Precisely locating where venous reflux is occurring — essential for any treatment planning.
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.

Asymmetric leg swelling — one leg noticeably larger than the other — is one of the most important warning signs of deep vein thrombosis (DVT). A blood clot forming in the deep veins of the leg obstructs venous return, causing swelling on that side only. This symptom warrants urgent evaluation with a venous duplex ultrasound.
Common signs of a DVT include swelling, warmth, redness, and aching in one leg — but up to half of all DVTs cause no symptoms at all.[3] The only reliable way to confirm or rule out a blood clot is with a venous duplex ultrasound. If you have any concern, do not wait — undetected DVT can progress to a pulmonary embolism.
Yes. Prolonged immobility during long-distance travel — flights over four hours or extended car rides — slows venous blood flow in the legs, increasing the risk of DVT. If you develop leg swelling or pain within days of travel, a venous duplex ultrasound can confirm or rule out a clot.
Yes. BlackPoint Diagnostics does not require a physician referral. Book directly online — evenings after 7pm and weekends. Results reviewed by a board-certified cardiologist and delivered within 24–48 hours.
