Do's

• No fasting is required for most vascular studies. Confirm with your doctor. Note: 4 hours fasting Required only for Renal Doppler • For carotid Doppler: avoid caffeine (tea, coffee, energy drinks) for two–three hours before the scan, as it can transiently affect blood flow measurements. • For lower limb venous Doppler (DVT scan): no specific preparation needed. Inform the sonographer if you have had a previous DVT or clot. • Continue all blood pressure, heart, and vascular medications as normal — do not skip them. • Bring any previous vascular reports, CT angiography, or Doppler studies. •Carotid / Neck vessels: Wear an open-collar or low-neck top. Remove necklaces.
• Upper limb vessels: Wear short sleeves. Remove watches and wrist jewellery.
• Lower limb vessels (leg arteries/veins): Wear or bring loose shorts. Be prepared to expose both legs from groin to ankle.

Don'ts

• No restrictions — resume normal activities immediately. ⚠ Note: If you have sudden leg swelling, redness, or pain and a DVT is suspected, please inform the reception staff on arrival so you can be prioritised. Note: 4 hours fasting Required in Renal Doppler
