What Does Colour Doppler Detect?

Colour Doppler ultrasound is an advanced imaging technique that combines traditional ultrasound with Doppler technology to visualize blood flow through vessels in real-time.

What is Colour Doppler?

Colour Doppler is a special ultrasound mode that shows the direction and speed of blood flow using color coding. Red typically indicates flow toward the transducer, while blue shows flow away from it.

What Does It Detect?

Colour Doppler can detect blood clots in veins (DVT), narrowing of arteries (stenosis), aneurysms, varicose veins, blood flow abnormalities in organs, placental blood flow during pregnancy, and thyroid nodule vascularity.

Common Applications

Carotid Doppler for stroke risk assessment, leg Doppler for DVT and varicose veins, renal Doppler for kidney blood flow, obstetric Doppler for fetal well-being, and thyroid Doppler for nodule evaluation.
