Doppler Ultrasound Hepatic
What is the exam?
This is a technique that uses ultrasound and therefore involves no exposure to any radiation or administration of contrast medium.
Guided by the principles of ultrasound and using Doppler technique, this exam visualises the arteries and veins, documents their permeability and describes the direction and speed of the blood flow inside the vessels.
This is a painless, non-invasive exam and no preparation is required, except for the abdominal Doppler ultrasound scan, for which a 5-hour fasting period is recommended.
This exam evaluates portal (portal hypertension, collateral veins and blood clots) and arterial circulation, the supra-hepatic veins and the inferior vena cava (IVC) in asymptomatic individuals, chronic hepatopathy patients or transplant recipients (it detects medical and surgical complications).
Preparation: 6-hour fasting period
