| Abstract
|
| [Objective] To explore the magnetic resonance imaging (MRI) features of different diagnostic classification in patients with acute ischemic stroke under the new clinical diagnostic framework for stroke.[Methods] A retrospective observational study was conducted,case information of 274 hospitalized patients with acute ischemic stroke admitted to our hospital from January 2017 to October 2018 was collected. Patients were divided into typical stroke group (156 cases) and atypical stroke group (118 cases) according to construction of clinical diagnostic framework of stroke. Chi-square test and Mann-Whitney U test were used to compare diffusion-weighted imaging (DWI) classification,area of infarction responsible blood vessels,infarction diameter and the degree of white matter lesions (WMLs) between the two groups.[Results] The cortical and subcortical infarction,the big penetrating branch infarction were related with typical stroke (P<0.05;P<0.01),the small penetrating branch infarction was related with atypical stroke (P<0.01). Anterior circulation and severe WMLs were related with typical stroke (P<0.01;P<0.05). Posterior circulation and mild WMLs were related with atypical stroke (P<0.01;P<0.05). The average maximum diameter of single lesions,the average maximum diameter and minimum diameter of multiple lesions in typical stroke group were higher than those in atypical stroke group (P<0.05).[Conclusion] There are different characteristics of MRI between typical stroke and atypical stroke. Anterior circulation infarction,the big penetrating branch infarction,massive cerebral infarction and severe WMLs mostly manifest as typical stroke. Posterior circulation infarction,the small perforating branch,lacunar infarction and mild WMLs mostly manifest as atypical stroke. |
