摘　　要：目的：探讨MRI检查在急性期脑出血诊断中的临床价值。方法回顾性分析2009～2011年收治的急性期脑出血患者54例患者影像学资料，所有患者均分别进行CT与MRI检查，对两种检查的诊断敏感性与对脑血肿量进行统计并做对比分析。结果 T2＊WI和CT的敏感性明显好于T1WI与T2WI的敏感性，差异具有统计学意义（P＜0.05）。CT、T1WI、T2WI、T2＊WI测量脑血肿量分别为（31.28±3.34）mL、（32.03±3.96）mL、（27.12±4.83）mL、（29.17±5.43）mL。CT与T2＊WI检测结果相接近，无明显差异（P＞0.05），T1WI与T2WI对脑血肿量的测量值较CT 和T2＊WI略小,但无明显统计学差异（P＞0.05）。CT与T2＊WI检查成像中较清晰，显示血肿部位有明显的边界和高信号。结论 MRI检查可有效检查出急性脑出血。MRI检查在急性期脑出血诊断中的临床价值不亚于CT检查，其可为急性脑出血诊断提供了重要的依据。Objective To investigate the clinical value of MRI in diagnosis of cerebral hemorrhage in acute phase. Methods The imaging data of 54 patients with the acute phase cerebral hemorrhage in our hospital from May 2011 to April 2012 were retrospectively analyzed. All patients were respectively examined by CT and MRI. The diagnostic sensitivity and hematoma volume of two check methods were statistically analyzed. Results The sensitivity of T2＊WI and CT were better than that of T1WI and T2WI, the differences were statistically significant（P〈0.05）. The brain hematoma volume of CT, T1WI, T2WI, T2＊WI was（31.28 ± 3.34） mL,（32.03 ±3 96） mL,（27.12 ± 4.83） mL,（29.17±5.43） mL. Measurement of cerebral hematoma volume of T1WI and T2WI value were slightly lower than the CT and T2＊WI, but no significant difference（P 〉 0.05）.The display of CT and T2＊WI were clear,with clear boundaries and high signal. Conclusion MRI can effectively detect cerebral hemorrhage in acute phase. MRI examination is not less than CT examination in the diagnosis of cerebral hemorrhage in acute phase. It can provide an important basis for diagnosis for the acute cerebral hemorrhage.
