Techniques and Principles of Magnetic Resonance Angiography

There are two main methods of acquiring angiographic images. We shall describe them from the point of view of intravascular flow imaging. Later, we shall describe recent refinements and modifications in the angiography methods. TOF MRA PC MRA

Each technique can be performed using 2D-FT. Thus, there are mainly four different methods:

Each of these techniques is advantageous to a different type of clinical application.

Before discussing these techniques, let us understand the basic physical principles of flow inside the vessel which is the fundamental principle of an-giography. This information is important for MR instrument physicists in day to day practice.
