![]() The names of the bright blood techniques TOF and PCA reflect the physical properties of flowing blood that were exploited to make the vessels appear bright. Technical parameters of the MRA sequence greatly affect the sensitivity of the images to flow with different velocities or directions, turbulent flow and vessel size.Ĭontrast enhanced magnetic resonance angiography (CE-MRA)Īll angiographic techniques differentially enhance vascular MR signal. MRA takes advantage of these artifacts to create predictable image contrast due to the nature of flow. Flow effects in MRI can produce a range of artifacts. With this different MRA techniques both, the blood flow and the condition of the blood vessel walls can be seen. There are bright blood and black blood MRA techniques, named according to the appearance of the blood vessels. This MRI technique creates soft tissue contrast between blood vessels and surrounding tissues primarily created by flow, rather than displaying the vessel lumen. ( MRA) Magnetic resonance angiography is a medical imaging technique to visualize blood filled structures, including arteries, veins and the heart chambers.
