Diagnosis of Deep vein thrombosis

Suspected DVT or PE is based on the history and the symptoms and is confirmed by ultrasound scanning or by a special x-ray taken after injecting a dye (contrast medium) that is opaque to X-rays (a venogram).

A more refined form of ultrasound examination called Doppler ultrasound, which can show how fast the blood is flowing in a blood vessel, is often used.
