Abstract
In this study, we compared the effectiveness of b0 echo-planar MR images (EPI) imaging
with gradient recalled echo (GRE) in detecting acute hemorrhage. Brain images in 69
patients who suffered from acute infarction were reviewed. Nine of them had suffered
from acute hemorrhage. Comparing b0EPI and GRE images side-by-side, we found no significant
different effectiveness in detecting hemorrhage (P = .522, ≥.05). We concluded that b0EPI imaging could detect hemorrhagic lesions as
effectively as GRE can without additional acquisition time.
