摘要 目的探讨多序列MRI在诊断急性脑出血中的价值。方法对临床36例急性期脑出血患者分别进行CT及MR检查,通过脑内血肿量及有经验医生的分析诊断,比较两项检查诊断的敏感性。结果T1WI、T2WI显示脑出血边界欠清,但空间分辨率较高。T2*WI显示血肿呈低信号,中心稍高信号,边界清楚。测量所得MR各序列和CT血肿量,T2*WI与CT两组间差异有显著性(P<0.05)。诊断敏感性比较T2*WI和CT组无显著性差异(P>0.05)。T1WI和T2*WI序列的敏感性相对较差,与CT组比较有显著性差异(P<0.01)。结论MR梯度回波T2*WI对诊断急性脑内血肿的敏感性和CT检查相当,结合常规扫描序列在急性期脑内血肿的诊断和鉴别诊断中具有实际应用价值。
