At ECR 2010 , the session will stress the numerous advantages of US and show how it could become a complement to other techniques in Austria Centre, Vienna, from March 4 - 8, 2010.

Ultrasound (US) has transformed vascular imaging at every step from diagnosis to treatment and follow-up. If properly used, it can provide both morphological and physiological information with very high accuracy. Its cheap cost, wide availability and non-invasiveness should make it one of the radiologists' favourite tools, but it is underused in comparison with CTA or MRA. The session presented at ECR 10 will stress the numerous advantages of US and show how it could become a complement to other techniques.

In the diagnosis of arterial diseases, US provides a measure of the geometrical severity of a lesion, and indicates pressure changes through the stenosis and its effects on the local circulation. In the early evaluation of disease, US provides inexpensive screening of aortic aneurysm and enables measurement of intimal thickening in carotid arteries, a predictor of increased cardiovascular disease. It can also be used in the measurement of arterial stiffness, which has shown to be an early indication of arterial disease.

Carotid US (CUS) enables identification of carotid stenosis and differentiation of stenosis from occlusion. This differentiation may enable the appropriate selection of candidates for endarterectomy or stent implantation. CUS is increasingly becoming the first and often the sole imaging study before treatment, where costly and invasive procedures are reserved for special cases. US is effective in determining the presence and extent of aneurysms, pseudo aneurysms, fistulas and dissections, and it has an important role in the follow‐up of surgical procedures and endovascular interventions. Careful manipulation of colour flow and Doppler controls and other parameters is necessary to successfully image and measure disease in large arteries. Renal arteries, for instance, require more skill and high specification equipment.

US is the major modality used in the detection and prevention of complications in deep venous thrombosis (DVT), a common condition that can potentially lead to pulmonary embolism. It is an excellent modality to diagnose various alternative conditions that clinically mimic DVT, thus preventing unnecessary anticoagulation treatment.
