Area of Science:

Biomedical Imaging
Medical Physics
Cell Biology

Background:

In vivo cell tracking relies on noninvasive imaging techniques.
Fluorine-19 (19F) MRI offers unique capabilities for visualizing and quantifying cells labeled with perfluorocarbon compounds.

Purpose of the Study:

To investigate 3D compressed sensing (CS) for accelerating 19F MRI data acquisition in cell tracking.
To evaluate the impact of CS acceleration on 19F signal quantification and image quality.

Main Methods:

Development and application of 3D CS methods for 19F MRI.
Phantom studies to assess image reconstruction, signal-to-noise ratio (SNR), and quantification accuracy.
In vivo studies using a mouse model of wounding-inflammation to quantify macrophage burden.

Main Results:

Achieved >8-fold reduction in 19F MRI imaging time with minimal image degradation.
Demonstrated preserved feature topology and no false positives in phantom studies with CS reconstruction.
Accurately reproduced 19F signal distribution in vivo with 8-fold acceleration, maintaining SNR.

Conclusions:

3D CS significantly accelerates 19F MRI for cell tracking.
This accelerated approach maintains quantification accuracy and image quality.
CS-enhanced 19F MRI holds promise for preclinical and translational cell tracking applications.
