Courtesy of Dr Pauline Hall Barrientos, this animated image demonstrates the 3D PC-MRI technique which visualises blood flow through vessels. This image illustrates 3D blood through a carotid with stenosis, showing high blood flow velocities (red colour = 100 cm/s) around the region of stenosis. It is hoped that 3D PC-MRI will improve the process of diagnosing and staging cardiovascular disease.
