A: Multiple in vivo axial ¹H MR images from one of the studied mice (eight out of ten acquired slices are shown, slice thickness = 1 mm). The ¹H images correspond to the same volume as the ¹⁹F MRI. A cylindrical sodium fluoride (NaF) phantom is also visible within the field‐of‐view. B,C: Corresponding ¹⁹F images of the two ISO peaks (slice thickness = 10 mm. D,E: Merged ¹H‐¹⁹F MRI of the reconstructed ¹⁹F images. For merging, a typical ¹H scan was chosen within the acquired stack. ¹⁹F localizes in the skeletal muscle and fat areas of the thorax.
