Study on Improved Computed Tomography Scanning Parameters for Patients with Nasal Bone Fracture Based on ITK Three-dimensional Labelling.

Objective: To investigate the influence of improved exposure parameters on the image quality of multi-slice spiral computed tomography in nasal bone fracture imaging.

Methods: Fifty patients with optimised parameters combined with coronal scanning were allocated to the modified group and 50 patients with routine scanning parameters to the routine group. The image quality and nasal bone display of the two groups were assessed and statistically analysed, and the quality of scanned images before and after parameter optimisation was compared.

Diffusion kurtosis imaging: An efficient tool for evaluating age-related changes in rat brains.

Purpose: To evaluate and determine age-related changes in rat brains by studying the diffusion kurtosis imaging results among different age groups of rats.

Methods: Sprague-Dawley (SD) rats underwent conventional magnetic resonance imaging (MRI) and diffusion Kurtosis Imaging (DKI). Two diffusion values of mean kurtosis (MK) and kurtosis (K ) were measured and analyzed based on laterality, brain regions and age groups.
