    Abstract
  •   Objective  To observe the characteristics of brain magnetic resonance imaging (MRI) in patients with vascular dementia after ischemic stroke and evaluate the value of MRI in the early diagnosis and monitoring of the disease.  Methods  A total of 200 patients with ischemic stroke who were treated in Taizhou Central Hospital from August 2016 to August 2020 were included in the study. Patients without vascular dementia after stroke were included in the control group, whereas patients with vascular cerebral infatuation after stroke were included in the study group. All patients underwent cranial MRI detection. Infarct size was observed, and the apparent diffusion coefficient (ADC) of the white texture region of interest was measured.  Results  In all 200 patients with acute ischemic stroke, the incidence of vascular cerebral infatuation was 26.50%. The proportions of patients with large and medium cerebral infarction in the study group (50.94% and 56.60%) were significantly higher than those in the control group (21.76% and 23.81%; χ2=15.943, 19.097; all P < 0.001). The volumes of the left and right hippocampi and the left and right cerebral diameters of the study group were significantly lower than those in the control group, and the distance between the uncinate gyrus of the temporal lobe in the study group was significantly higher than that in the control group (all P < 0.001). The ADC values of the white matter in the frontal area of the frontal lobe, posterior area of the frontal lobe, anterior horn of the lateral ventricle, posterior horn of the lateral ventricle, semioval centre and hippocampus were significantly lower in the study group than in the control group (all P < 0.001).  Conclusion  Patients with vascular dementia after ischemic stroke have the characteristics of cortical atrophy, widened sulcus, large infarct area and sparse white matter. MRI examination can effectively diagnose the clinical features of vascular dementia after ischemic stroke and has a clinical value for early treatment and prognosis evaluation.
