Absorption component shape spectra

Figure 4.5 The initial convergence regions (panels (i), (iv)), absorption total shape spectra (panels (ii), (v)), and absorption component shape spectra (panels (iii), (vi)) in the FPT+) (left column) and FPT-) (right column). The middle panels display the usual abbreviations for the main MR-detectable metabolites in the healthy human brain, whereas the bottom panels give the corresponding numbers of these metabolites (see Table 4.1).

Figure 4.8 Absorption component shape spectra (left) and absorption total shape spectra (right) from the FPTf 1 near full convergence for signal lengths Np = 180,220,260. On panel (iv) for Np = 180, the total shape spectrum reached full convergence, despite the fact that on panel (i) for the corresponding component shape spectra, the 11th peak is missing and the 12th peak is overestimated.

We present the absorption component shape spectra and the total shape spectra as reconstructed by the FPT for the normal breast data in Figure 6.10 at three partial signal lengths Np = 1000,1500, and 2000. The top right panel (iv) indicates that at Np = 1000, the absorption total shape spectrum has converged. In contrast, for the component shape spectrum (top left panel (i)), there is only one peak (phosphoethanolamine. A = 5) at 3.22 ppm that has been overestimated, whereas phosphocholine, (A = 4) has not been detected.

The Pad6-reconstructed absorption component shape spectra for the normal glandular prostate are shown in Figure 6.18 at Np = 54 and Np = 800. The upper panel reveals that at Np = 54, only 12 of fhe 27 resonances were resolved. These correctly resolved peaks were mainly at the two extremes of the spectrum (lactate and alanine at 1.33 and 1.49 ppm and myoinositol...
