ABSTRACT
Objective To investigate the predictive value of Alberta stroke program early CT score on diffusion-w eighted imaging (DWI-ASPECTS) for predicting new cerebral microbleeds (CMBs) in patients w ith acute middle cerebral artery infarction. Methods The patients w ith acute middle cerebra artery infarction w ere enroled prospectively. MRI examinations w ere completed w ithin 48 h on admission and they w ere examined again at 10 to 14 d after onset. Susceptibility-w eighted imaging (SWI) w as use to detect CMBs. DWI-ASPECTS w as used to assess the infarction extent. Results A total of 82 patients w ith acute middle cerebra artery infarction w ere enroled, including 27 females and 55 females. Their ages w ere 71.7 ± 8.9 years. Eighteen patients (22.0%) had old CMBs, 25 (30.5%) had new CMBs, 57 (69.5%) did not have new CMBs. Compared w ith the non-new CMB group, DWI-SPECTS (3.20 ±1.73 vs.7.11 ±1.69;t = 9.573, P 5), the risk of new CMBs w ould decrease 86 % (odds ratio 0.14, 95%confidence interval 0.17 -0.48; P < 0.001). Receiver operating characteristic curve analysis show ed that the sensitivity of prediction of DWI-ASPECTS ≤5 for the new CMBs w as 87.7%, specificity w as 88.3%, and the area under the curve w as 0.940. Conclusions DWI-ASPECTS can effectively predict the new CMBs in patients w ith acute middle cerebra artery infarction.
