The blood vessels are part of the Circulatory system and function to transport Blood throughout the body Bruit (ˈbruːt or as French bʁɥi is the term for the unusual sound that blood makes when it rushes past an obstruction (called Turbulent flow) in an Artery This bruit can be made audible by a stethoscope. The stethoscope (from Greek στηθοσκόπιο, of στήθος stéthos - chest and σκοπή skopé - examination) is an acoustic Other, more reliable methods of diagnosing a stenosis are imaging methods including ultrasound, Magnetic Resonance Imaging/Magnetic Resonance Angiography, Computed Tomography/CT-Angiography which combine anatomic imaging (i.
