Intracranial Vessel Wall MRI: Principles and Expert Consensus Recommendations of the American Society of Neuroradiology

Key points:

  • To review the principles of intracranial VW-MR imaging and provides consensus recommendations for clinical practice.

Conventional techniques for imaging the intracranial arteries can fail to fully characterize disease that resides within the vessel wall. For this reason, there is growing interest in direct visualization of the vessel wall with high-resolution intracranial vessel wall MR imaging (VW-MR imaging).

The principal technical requirements for intracranial VW-MR imaging are the following:

High spatial resolution

Multiplanar 2D or 3D acquisitions

Multiplanar 2D or 3D acquisitions

Suppression of signal in luminal blood and CSF

Clinical uses of VW-MR

SITUATIONS IN WHICH INTRACRANIAL VW-MR IMAGING IS LIKELY A USEFUL ADJUNCT TO CONVENTIONAL IMAGING
