We proposed a new computed DWI technique allowing
to provide quantitative maps of ADC, T2, T1 and DWI images with arbitrary contrast of PDW, T2W, and T1W. We clarified that our techniques enabled to provide
FLAIR-DWI images with higher SNR than actually measured FLAIR-DWI, and furthermore enhanced
by using SE-based ADC map and SE- or IR-based T1 map with optimal TI for brain
tissue. Although further optimization is required, it is expected to be especially
useful for clinical brain diagnosis.
