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, > or =.05). We concluded that b0EPI imaging could detect hemorrhagic lesions as effectively as GRE can without additional acquisition time.
在本研究中，我们比较了b0回波平面磁共振成像（EPI）与梯度回波（GRE）在检测急性出血方面的有效性。回顾了69例急性梗死患者的脑部图像。其中9例发生了急性出血。将b0EPI和GRE图像并排比较，我们发现在检测出血方面两者的有效性无显著差异（P = 0.522，>或= 0.05）。我们得出结论，b0EPI成像在不增加采集时间的情况下，检测出血性病变的效果与GRE相同。
