MRA is known as Magnetic Resonance Angiography. It is a technique in which it takes the image of blood vessels with help of Magnetic Resonance Imaging. Magnetic Resonance Angiography is used to generate pictures of the arteries in order to evaluate them for abnormal narrowing also called stenosis or aneurysms. Aneurysms in which the vessel wall dilate and at risk of rupture. MRA is frequently used to analyze and measure the arteries of the brain and neck, renal arteries, abdominal and thoracic aorta, and the legs. Different types of methods can be used to produce the images, such as gadolinium (management of paramagnetic contrast agent) or using a procedure known as flow-related enhancement (e.g. 2D and 3D time-of-flight series), where the majority of the signal on an image is because of the blood which has currently shifted into that plane.

MRV (Magnetic Resonance Venography) is a same kind of procedure that is used to image veins. In this technique the tissue is now energized inferior while signal is collected in the plane at once superior to the excitation plane, and therefore picturing the venous blood which has freshly moved from the excited plane.
