Multi-targeted ¹H/¹⁹F MRI unmasks specific danger patterns for emerging cardiovascular disorders

Area of Science:

• Biomedical imaging
• Nanotechnology
• Cardiovascular research

Background:

• Predicting acute coronary syndromes (ACS) remains challenging.
• Vascular inflammation and atherothrombosis precede myocardial infarction.
• Current methods lack predictive capability for imminent cardiac events.

Purpose of the Study:

• To develop a multi-targeted nanotracer platform for early visualization of coronary inflammation and atherothrombosis.
• To identify high-risk areas predictive of myocardial infarction in mice.
• To establish a technology with disease-predictive potential for various conditions.

Main Methods:

• Utilized multi-color nanotracer platform with ligand-equipped perfluorocarbon nanoemulsions.
• Employed multi-chemical shift selective 19F MRI for simultaneous visualization.
• Differentiated nanoemulsions by spectral signatures for targeted imaging.

Main Results:

• Successfully visualized evolving danger patterns in progressive coronary inflammation and atherothrombosis.
• Identified high-risk areas predictive of spontaneous myocardial infarction in mice.
• Demonstrated early detection prior to conventional parameter indication of danger.

Conclusions:

• The developed nanotracer platform enables simultaneous visualization of atherothrombosis progression.
• This technology can predict myocardial infarction risk at an early, pre-symptomatic stage.
• The multi-targeted approach is adaptable for monitoring diverse disease entities.
