Synopsis

Keywords: Contrast mechanisms: Diffusion, Neuro: White matter

Various methods, such as diffusion tensor imaging, diffusion kurtosis imaging, and Q-ball imaging (QBI), are used to evaluate the white matter using diffusion-weighted imaging (DWI). Generally, the more the motion-probing gradients (MPG), the more accurate the white matter evaluation. In contrast, the scan time becomes longer in proportion to the number of MPGs. Regarding these evaluation methods, focusing on the number of MPGs, I explained the relation between scan time (clinically acceptable scan time) and quantification (image quality). Furthermore, I introduced the technology to shorten the scan time and to increase the possibility of clinical application.
