Abstract
Objective To investigate the early diagnostic value of susceptibility weighted imaging (SWI) on hemorrhagic transformation (HT) after massive cerebral infarction.
<br> Methods Thirty nine cases with massive cerebral infarction diagnosed by magnetic resonance were enrolled and head computed tomography (CT) and magnetic resonance imaging (MRI) including SWI were performed within 72 hours after onset. The detection rate and the sensitivity of two methods for diagnosing HT were compared. The HT after cerebral infarction was graded based on European Cooperative Acute Stroke Study (ECASS), the difference in HT grade by two examination methods was compared, HT grading and the National Institutes of Health Stroke Scale (NIHSS) score correlation were analyzed.
<br> Results The positive rates of SWI or CT in the diagnosis of HT were 61.54% and 12.82%(P<0.001) respectively. Twenty four cases (61.54%) with HT after massive cerebral infarction were detected by SWI, grade 1 accounted for 12.82%, and grade 2, 3, 4 for 25.64%, 15.48%and 7.69%, respectively. SWI was signiifcantly superior to conventional CT in early detection of hemorrhagic transformation after massive cerebral infarction. HT grading by SWI was positively correlated with NIHSS scores (R=0.94, P<0.01).
<br> Conclusion The HT after massive cerebral infarction can be early, sensitively, objectively evaluated by SWI, which provides the basis for the adjusting treatment programs.关键词
