In the medical field, 19F tracking is a hallmark application of multi-nuclei MRI. To evaluate the performance of this new system, we used perfluorocarbon (PFC) as an MRI contrast agent and injected it into the ex vivo porcine sample to obtain 1H/19F images. The 1H image details the structure of the porcine sample (muscle and fat), while the 19F image shows the location of the PFC. We found that combining these images allows precise tracking and analysis of specific chemical substances within the sample.
