3D Contrast Enhanced Microvascular Ultrasound of Carotid Atherosclerosis for the Detection of Carotid Plaque Neo-Revascularisation.

Atherosclerotic plaques, the build-up of fatty materials within our arteries, can develop over a long period of time without causing any symptoms. These plaques may continue to grow and rupture causing narrowing and blockages of the blood vessels. This can lead to serious cardiovascular disease such as a heart attack or stroke causing over 160,000 deaths each year. Lots of research has been done on why particular groups of people may develop atherosclerosis and controlling risk factors such as diabetes and high blood pressure go a long way to reduce people's risks. However, despite the treatments we have available and controlling these risk factors, some people unfortunately still go on to develop a potentially serious disease. Further research has shown us that certain plaques in the blood vessels may be more vulnerable to rupturing compared to others. So far we know that plaques with thin caps, soft centres or those that are able to grow their own tiny blood vessels are more likely to rupture. We have now started to develop new imaging methods to try and help us detect these vulnerabilities. The hope is by being able to detect more vulnerable plaques we may be able to treat these earlier and therefore more effectively. There are different scans available to try and visualise the tiny vessels within these plaques in the neck arteries. These include, MRI (a Magnetic Resonance Imaging scan, taking pictures using a small tunnel), CT (Computed Tomography, uses a ring-shaped …
