Functional Imaging Using Fluorine (¹⁹F) MR Methods: Basic Concepts.

Area of Science:

• Biomedical imaging
• Medical diagnostics

Background:

• Kidney pathologies require objective, noninvasive methods to assess renal function.
• Fluorine-19 MRI (¹⁹F MRI) is emerging as a valuable tool for in vivo biomedical research.
• ¹⁹F MRI enables quantification of exogenous substances, crucial for disease state monitoring.

Purpose of the Study:

• Introduce the concept and potential of ¹⁹F MRI for renal function assessment.
• Highlight challenges and preclinical applications of ¹⁹F MRI in nephrology.
• Illustrate the utility of ¹⁹F MRI for measuring renal function in animal models.

Main Methods:

• Utilizes exogenous ¹⁹F substances for imaging.
• Leverages the absence of endogenous fluorine in eukaryotic cells for background-free detection.
• Focuses on preclinical applications in animal models for renal function evaluation.

Main Results:

• ¹⁹F MRI provides highly selective and specific detection in vivo.
• Demonstrates the potential for background-free imaging crucial for sensitive measurements.
• Preclinical studies showcase the applicability for assessing renal function.

Conclusions:

• ¹⁹F MRI is a promising technique for noninvasive quantification of renal function.
• Overcoming signal sensitivity challenges will further enhance its clinical utility.
