Quadruple Contrast Enhancement with MRA and MR Spectroscopic Imaging

This approach minimized the false tissue classifications by: (1) improving the lesion-to-tissue contrast on MR images by developing a fast imaging pulse sequence that incorporated both cerebrospinal fluid signal attenuation and magnetization transfer contrast (see Fig. 3.33); and (2) including information from MR flow images [24]. In pathologically defined abnormalities in the cortical gray matter (GM) and normal volunteers, high resolution MRI and short echo

Figure 3.33: An approach is represented to improve the multiple sclerosis lesion-to-tissue contrast using MRA images by a fast imaging pulse sequence incorporating both cerebrospinal fluid signal and flow attenuation with magnetization transfer contrast. The technique suppressed gray matter or white matter and highlighted the lesion-to-tissue contrast.
