磁共振3D-T1WI及扩散张量成像在评估意识障碍中的研究进展
Research Progress of Magnetic Resonance 3D-T1WI and Diffusion Tensor Imaging in the Assessment of Disorders of Consciousness
摘要
Abstract
Disorders of consciousness(DOC)are a group of severe neurological disorders.Accurate assessment of the severity of DOC and related pathophysiological mechanisms is crucial for patients'treatment and prognosis.Traditional imaging examinations,such as conventional magnetic resonance imaging or computed tomography,have limitations in evaluating microstructural changes and brain functional connectivity in DOC patients.Magnetic resonance 3D-T1 weighted imaging(3D-T1WI)and diffusion tensor imaging(DTI)can objectively reflect abnormal brain structural and functional changes,provide detailed imaging evidence for exploring the pathophysiological mechanisms of DOC,and possess unique advantages in the field of DOC assessment.This paper reviewed the latest applications of 3D-T1WI and DTI in DOC assessment,summarized the changes in brain structure and function as well as their pathophysiological mechanisms in DOC patients,and aiming to provide a reference for the diagnosis,prognosis,and treatment of DOC.关键词
