• No Fasting Required: You may eat and drink normally before your appointment.
• Clothing: Wear loose, comfortable clothing. You will need to expose your arms from the shoulders to the wrists and your legs from the groin to the ankles. A clinical gown is often provided.
• Avoid Nicotine: Refrain from smoking or using nicotine products for at least 2 hours before the test. Nicotine constricts blood vessels and can lead to inaccurate flow readings.
• Temperature: Avoid extreme cold before the test, as it can cause peripheral vessels to shrink (vasoconstriction).
• Medication: Continue all regular medications unless your doctor specifically tells you otherwise.
• Comfort: The test is completely painless. A clear, water-based gel is applied to the skin to help the ultrasound transducer glide easily and transmit sound waves.

This comprehensive scan is essential for a systemic evaluation of the body’s peripheral circulation:

Key clinical uses include:

• Deep Vein Thrombosis (DVT) Screening: The venous portion of the scan is critical for identifying blood clots in the deep veins of the legs or arms, which can lead to a pulmonary embolism if left untreated.
• Peripheral Artery Disease (PAD) Detection: The arterial portion identifies plaque buildup (atherosclerosis) that can cause limb pain, cramping (claudication), or non-healing ulcers.
• Chronic Venous Insufficiency (CVI): The test evaluates the health of the valves in your veins to see if blood is pooling in the limbs, which causes varicose veins and swelling.
• Systemic Vascular Check: For patients with systemic diseases such as Diabetes or Hypertension, this 4-limb study ensures adequate circulation in all extremities.
• Pre-Surgical Clearance: Often used before major surgeries to ensure there are no hidden clots or significant arterial blockages that could complicate recovery.
