- W2352267415 abstract "Objective To analyze the features of susceptibility-weighted imaging(SWI) of leptomeningeal collaterals in ischemia stroke and its clinical correlation. Methods Totally 66 patients with clinically or radiologically proved cerebral infarction,including 26 acute,29 subacute and 11 chronic cerebral infarction,were examined with MRI. All patients received conventional sequences including T1WI,T2WI,FLAIR,DWI and SWI. Twenty- seven patients underwent MRA,and 36 patients were followed by SWI. Features of routine MRI and SWI were studied. The presence of leptomeningeal collaterals around the infarction was observed. The correlation between the extent of the leptomeningeal collateral and the NIHSS score was analyzed. Results Leptomeningeal collateral was revealed by SWI in 45 out of 66(68%) cerebral infarctions,including 41cases in acute and subacute cerebral infarction,and 4 cases in stable and chronic stage. The visualization of collateral vessels around the infarction in different stages has significant difference(P 0. 05). Twenty cases showed degree 2 collaterals. There was a positive correlation between the degree of leptomeningeal collateral displayed in the SWI and the NIHSS scores(rs= 0. 673,P 0. 01). Conclusion Quantitative analysis of SWI features of leptomeningeal collaterals in ischemic stroke can help determine the establishment of collateral circulation of cerebral infarction,guide the clinical treatment and evaluate the prognosis." @default.
