Summary
Cross-sectional imaging, including cardiac magnetic resonance imaging (MRI) and multislice spiral computed tomography (MSCT), is now clinically accepted for analyzing left ventricular (LV) function, impacting diagnosis and patient outcomes.
Area of Science:
- Radiology
- Cardiology
- Medical Imaging
Background:
- Cross-sectional imaging is increasingly vital for left ventricular (LV) function analysis.
- LV function parameters impact diagnosis, therapy, and mortality prediction.
- Cardiac MRI and MSCT are advanced radiologic techniques for LV function assessment.
Purpose of the Study:
- To review the theoretical and technical aspects of cardiac MRI and MSCT.
- To outline the opportunities and limitations of MRI and MSCT for cardiac functional imaging.
- To provide a comprehensive overview of advanced imaging modalities for LV function.
Main Methods:
- Cardiac MRI utilizes cine sequences, parallel imaging, fast imaging with steady state free precession, and real-time sequences.
- Stress examinations and MR-tagging enhance cardiac MRI capabilities.
- Cardiac MSCT with retrospective ECG-gating enables reliable LV volume determination and wall motion assessment.
Main Results:
- Cardiac MRI offers advanced techniques for comprehensive LV function analysis.
- Cardiac MSCT provides a viable alternative for patients with MRI contraindications.
- Both MRI and MSCT demonstrate significant clinical utility in assessing LV function.
Conclusions:
- MRI and MSCT are established tools for quantitative and qualitative analysis of LV function.
- These imaging modalities significantly influence clinical decisions in cardiology.
- Understanding the capabilities and constraints of MRI and MSCT is crucial for optimal patient care.
