MR angiography, also known as magnetic resonance angiography, is a specialized procedure that uses MRI imaging to visualize the cerebral vessels.
Limitations
MR angiography provides results of similar quality to digital subtraction angiography for visualizing the intracranial vessels; however, it is more susceptible to artifacts and, depending on the MRI scanner, may also be inferior in quality to digital subtraction angiography[^1] [^2] [^3]. Unlike conventional digital subtraction angiography, MRA generally acquires three-dimensional datasets rather than two-dimensional projection images, allowing the vessels to be assessed from all viewing angles. Another difference from conventional angiography is that MRA does not require a catheter to be inserted into the vascular system.
