- Biomedical Engineering
Background:
- Coronary heart disease (CHD) screening requires noninvasive methods.
- Magnetic resonance imaging (MRI) presents a potential risk-free approach.
- Challenges include cardiac/respiratory motion and coronary artery anatomy/flow.
Purpose of the Study:
- To review research efforts in overcoming MRI challenges for coronary artery imaging.
- To assess the progress and current state of noninvasive coronary artery visualization.
Main Methods:
- Utilizing 2D and 3D imaging techniques.
- Employing various MRI sequences like spin echo and gradient echo.
- Implementing saturation pulses and contrast agents to enhance image quality.
Main Results:
- Promising results have been reported by multiple research groups.
- Advancements in MRI techniques show potential for improved coronary artery visualization.
- No single optimal solution has been definitively established yet.
Conclusions:
- Coronary artery MRI is a developing field with significant potential.
- Continued research is necessary to refine techniques and establish optimal solutions.
- Noninvasive screening for CHD via MRI is a feasible future goal.
