Advances in spinal cord MR angiography

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Spinal cord vascular imaging is crucial for diagnosing and treating neurological conditions.
• Non-invasive techniques are needed to complement or replace traditional catheter angiography.

Purpose of the Study:

• To review novel Magnetic Resonance (MR) angiography developments for spinal cord vascular imaging.
• To highlight the clinical utility of these advancements in diagnosing spinal cord vascular abnormalities.

Main Methods:

• Review of current fast contrast-enhanced MR angiography techniques.
• Focus on visualization of spinal cord arteries and veins.
• Assessment of techniques for localizing the Adamkiewicz artery.

Main Results:

• MR angiography can now visualize spinal cord arteries and veins.
• Reproducible localization of the Adamkiewicz artery is achievable.
• These techniques offer a non-invasive alternative to catheter angiography for vascular lesion detection.

Conclusions:

• Spinal cord MR angiography is a viable diagnostic tool.
• Pre-procedural imaging is essential for aortic aneurysm surgery to prevent ischemic injury.
• Clinical success depends on understanding spinal cord vasculature and post-processing skills.
