Comparative Study
Quantitative evaluation of diffusion-kurtosis imaging for grading endometrial carcinoma: a comparative study with diffusion-weighted imaging.
To evaluate the diagnostic performance of histogram analysis of diffusion kurtosis magnetic resonance imaging (DKI) and standard diffusion-weighted imaging (DWI) in discriminating tumour grades of endometrial carcinoma (EC). ⋯ Entire-tumour volume histogram analysis of DKI and standard DWI were feasible for discriminating histological tumour grades of EC. DKI was relatively better than DWI in distinguishing high-grade from low-grade tumour in EC.

To describe the pattern of cervical spine fractures in adult major trauma and identify computed tomography (CT) parameters that can predict significant ligament injury when fractures are absent; to define the normal range for parameters used; and identify common variations due to position of cervical immobilisation in a trauma patient. ⋯ When fractures are absent, signs of significant ligament injury on CT at the craniocervical junction were increased basion dens interval and widened facet joints. In the subaxial cervical spine, >50% subluxation of a facet joint and obscured posterior paraspinal fat pad are indicators of significant ligament injury.
