MR Imaging for Intracranial Vessel Wall Imaging: Pearls and Pitfalls

Area of Science:

• Radiology
• Medical Imaging
• Neurology

Background:

• Conventional vascular imaging focuses on the lumen, missing vessel wall abnormalities.
• Cerebrovascular pathologies often involve the vessel wall, necessitating advanced imaging.
• High-resolution vessel wall imaging (VWI) is emerging for detailed vessel wall assessment.

Purpose of the Study:

• To highlight the growing importance and applications of VWI.
• To emphasize the need for understanding VWI protocols and imaging characteristics.
• To support radiologists in interpreting VWI for vasculopathies.

Main Methods:

• Review of VWI advancements over the past two decades.
• Analysis of increasing publication trends in VWI.
• Discussion of clinical applications and imaging characteristics.

Main Results:

• Significant increase in VWI publications indicates growing interest and utility.
• Improvements in imaging techniques have enhanced VWI capabilities.
• Expansion of clinical applications demonstrates VWI's broader relevance.

Conclusions:

• VWI is increasingly vital for studying vessel wall abnormalities in cerebrovascular diseases.
• Proper VWI protocols and understanding imaging features are essential for radiologists.
• VWI represents a significant advancement in vascular imaging beyond lumen assessment.
