Figure 6:

Depiction of a representative time-point, T₁ map, and T₂ map for [¹³C,¹⁵N₂]urea (A-C), [¹³C]urea (D-F), and [2-¹³C]pyruvate (G-I) from a dual module acquisition (T₁ mapping followed by T₂ mapping) (N = 1 for all compounds). The T₁ maps matched up well with the global T₁ as well as the HP001 T₁ maps in Figures 4-5, with the longest T₁’s seen in the kidneys. The T₂ maps of each compound matched up well with previously acquired maps, with the longest T₂ values seen in the kidneys due to renal filtration. Additionally, the [¹³C,¹⁵N₂]urea maps showed the capability of 1.25 x 1.25 mm² spatial resolution for T₁/T₂ mapping. For ¹H anatomical image, see Figure 7A.
