Investigation of Brain Impairment Using Diffusion-Weighted and Diffusion Tensor Magnetic Resonance Imaging in Experienced Healthy Divers.

摘要: BACKGROUND The aim of this study was to understand the changes decompression illness in healthy divers by comparing diffusion-weighted (DWI) and diffusion tensor MRI findings among professional non-divers with no history diving. MATERIAL AND METHODS A total 26 people were recruited prospective study: 11 experienced neurological disease (cohort) 15 (control). In all subjects, we evaluated apparent coefficient (ADC) type metric fractional anisotropy (FA) values different brain locations (e.g., frontal parieto-occipital white matter, hippocampus, globus pallidus, putamen, internal capsule, thalamus, cerebral peduncle, pons, cerebellum, corpus callosum). RESULTS ADC hippocampus high but low control group; FA pallidus putamen lower compared group. DWI depicted possible due hypoxia regions brain. Statistically significant differences found hypoxia, particularly (p=0.0002), while statistically (p=0.015 p=0.031, respectively). We detected forgetfulness 6 deterioration fine-motor skills 2 (p=0.002 p=0.17, All them examined using neuro-psychometric tests. CONCLUSIONS Repeated hyperbaric exposure increases risk matter damage without illness. are areas responsible for memory, learning, navigation, sensitive repeated exposure.
