Comparative Study
Comparing the value of DKI and DTI in detecting isocitrate dehydrogenase genotype of astrocytomas.
To compare the value of diffusion kurtosis imaging (DKI) and diffusion tensor imaging (DTI) in evaluating astrocytomas with an isocitrate dehydrogenase (IDH) genotype. ⋯ DKI may be a new imaging biomarker for evaluating the IDH genotype of astrocytomas, which is more accurate and stable than DTI.

Comparative Study
Diffusion-weighted imaging of the kidney: comparison between simultaneous multi-slice and integrated slice-by-slice shimming echo planar sequence.
To compare the simultaneous multi-slice (SMS) and integrated slice-by-slice shimming (iShim) single-shot echo planar imaging (ssEPI) for diffusion-weighted imaging (DWI) of the kidneys. ⋯ SMS can substantially reduce imaging time of kidney DWI with slightly improved image quality and comparable ADC values of renal parenchyma compared to iShim ss-EPI sequence.
