The purpose of this study was to propose a short-TE
computed diffusion imaging (cDWI) technique for
enhancing CNR for short T2 and low ADC tissues to
backgrounds. Here we assessed for simulation, phantom
and volunteer brain. The CNRs for the fiber
portions-to-background were enhanced and T2
shine-thorough effects in water or CSF were reduced in
short-TE cDWI images. In conclusion, the short-TE cDWI
technique is useful for suppressing tissues of high ADC
with longer T2 and enhancing tissues of low ADC with
short T2; and thus regarded as clinically useful for
enhancing neuronal fibers (neurography) or short T2
tumors.
