Diffusion-weighted magnetic resonance neurography for parapharyngeal schwannomas: preoperative determination of the originating nerves.
The aim of this study was to assess the feasibility of diffusion-weighted (DW) magnetic resonance neurography (MRN) for determining the originating nerve of parapharyngeal schwannomas preoperatively. ⋯ The DW-MRN is a feasible approach for determining an originating nerve.

A histogram-based similarity measure for quantitative magnetic resonance imaging: application in acute mild traumatic brain injury.
The most commonly used summary metric in neuroimaging is the mean value, but this pays little attention to the shape of the data distribution and can therefore be insensitive to subtle changes that alter the data distribution. ⋯ Our results show that HSM is more sensitive than the standard mean values in detecting brain tissue changes. Future studies on brain tissue properties using quantitative magnetic resonance imaging should consider the use of HSM to properly capture any tissue changes.
