3.0T MRI磁敏感加权成像在老年人急性脑梗死伴出血的诊断价值
The application of 3.0T MRI susceptibility weighted imaging in evaluation of acute brain infarction with hemorrhage in elderly patients
摘要
Abstract
Objective To investigate the value of 3.0T MRI susceptibility weighted imaging (SWI) in the diagnosis of acute brain infarction with hemorrhage in elderly patients.Methods Patients with suspected acute brain infarction received MRI examination using routine sequences,diffusion-weighted imaging (DWI) and SWI sequences for imaging evaluation of infarction as well as detection of possible micro-hemorrhage.Results Among 128 suspected cases,acute infarction was diagnosed in 67,73 and 46 patients based on routine MRI imaging,DWI and SWI,respectively.Further analysis revealed 12,13 and 19 hemorrhagic lesions in routine MRI imaging,DWI and SWI,respectively.With regard to intracranial distribution,cererbral region predominated.Conclusions For assessment of acute brain infarction with hemorrhage,SWI is more sensitive than DWI and routine MRI.However,the value of SWI is limited in evaluating lesions located in cerebellum and brain stem due to imaging artifacts from skull base.关键词
