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.
