Figure 5. Multi-TE Images of a Representative C57BL/6J Mouse.

Axial slice of mouse lung acquired at TE = (a) 0.08 ms, (b) 0.25 ms, (c) 0.50 ms, (d) 1.25 ms, and (e) 2.50 ms. Windowing and leveling were identical for all images. Lung regions include the airways (blue arrows), parenchyma (white arrow), and vasculature tissue (red arrows). (f) Resulting $\text{a}{\mathrm{T}}_2\mathrm{*}$ map of the lung parenchyma fit from multi-TE images to an exponential decay function (Eq. 2).
