A portrait in blood vessels.Magnetic resonance angiography (MRA) is a specialised medical imaging technique used to visualise blood vessels. Here, tangled white tubes represent the major blood vessels of the head, neck and upper thorax. Looking at the uppermost portion of the image, one can see the silhouette of the brain whilst the aortic arch takes the center bottom. All these vessels are hard at work beneath your skin, even as you read this post. -- source link
