Coronary artery wall imaging.

Area of Science:

• Cardiovascular Imaging
• Medical Physics
• Radiology

Background:

• Current MR coronary angiography visualizes only vessel lumens, not the vessel wall.
• Outward remodeling, an early sign of subclinical coronary disease, is missed by lumen-only imaging.
• Existing gold standards like intravascular ultrasound and optical coherence tomography are invasive and use ionizing radiation.

Purpose of the Study:

• To review the current state of Magnetic Resonance (MR) coronary vessel wall imaging.
• To discuss validation studies and recent advancements in this noninvasive imaging technique.
• To highlight the potential of MR vessel wall imaging for early detection and monitoring of preclinical coronary artery disease.

Main Methods:

• Review of existing literature on MR coronary vessel wall imaging techniques.
• Discussion of validation studies comparing MR imaging with invasive methods.
• Analysis of recent technological developments and their impact on image quality and diagnostic capabilities.

Main Results:

• MR coronary vessel wall imaging provides insights into the vessel wall beyond lumen visualization.
• Studies demonstrate the feasibility and accuracy of MR imaging in detecting vessel wall changes.
• Recent developments have improved spatial resolution and reduced scan times for MR coronary vessel wall imaging.

Conclusions:

• Noninvasive MR coronary vessel wall imaging is a promising tool for assessing preclinical coronary artery disease.
• This technique overcomes limitations of traditional angiography and invasive methods.
• MR vessel wall imaging facilitates early disease detection and safe longitudinal monitoring of disease progression or regression.
