Dynamic cardiac MRI offers comprehensive resting evaluations but cannot yet screen for coronary artery disease. Future advancements aim to enable stress testing and coronary artery disease detection with real-time imaging and perfusion agents.

Area of Science:

Cardiovascular Imaging
Magnetic Resonance Imaging

Background:

Current dynamic cardiac MRI provides effective resting cardiac structure and function assessment.
A key limitation is the inability to screen for coronary artery disease or assess ventricular function under stress.

Purpose of the Study:

To explore the future capabilities of dynamic cardiac MRI.
To identify advancements that will enable stress testing and coronary artery disease detection.

Main Methods:

Review of existing and developing technologies in cardiac MRI.
Discussion of potential applications of ultrafast imaging, real-time imaging, and perfusion markers.

Main Results:

Future MRI will likely offer routine quantification of vascular flow rates.
