This method allows for the calculation of pixel-wise FID spectra based on a 3D spiral UTE imaging sequence. Images were acquired for 36/72 TE and extrapolated. The method is advantageous for rapidly decaying 1H signals such as those of collagen in tendons or fibrotic tissue. A phantom (6 collagen solutions) served for evaluation. Resulting spectra are comparable to a standard non-localized FID spectrum and show positive correlation between collagen concentration and signal. First in-vivo results recorded in the subcutaneous adipose tissue exhibit the typical fat resonances. The presented UTE-FID spectroscopy seems feasible for spatially resolved applications of rapidly decaying signals.
