The real MR images were used for performance evaluation. They were acquired from ten patients with normal physiology. One example is shown in Fig. 2(a)-(e) with the same parameter values in Table 1. Band 1 is the PD-weighted spectral image acquired by the pulse sequence TR/TE = 2500ms/25ms. Bands 2, 3 and 4 are T2-weighted spectral images were acquired by the pulse sequences TR/TE = 2500ms/50ms, TR/TE = 2500ms/75ms and TR/TE =2500ms/100ms respectively. Band 5 is the T1-weighted spectral image acquired by the pulse sequence TR/TE = 500ms/. The tissues surrounding the brain such as bone, fat and skin, were.
