摘　　要：目的:旨在研究用磁共振成像(MRI)T2*WI检测临床自发性脑出血患者脑内含铁病灶的演变过程。方法:收集临床自发性脑出血患者10例,于发病后第1、7和14天行头颅MRIT1WI、T2WI、DWI和T2*WI系列扫描,记录图像特征,由Image J软件进行图像分析。结果:患者脑出血后MRI T2*WI序列显示的含铁病灶图像与其他MRI序列比较明显清晰;发病后第7和14天含铁病灶范围测量显示T2*WI序列比T2WI序列所测得的体积更大(P<0.05)。结论:住自发性脑出血脑内含铁病灶的检测中,MRI T2*WI序列较其他MRI序列图像更为清晰,与MRI T2WI相比也更为敏感。Aim： To detect the iron-containing lesions using MRI T2^＊WI after spontaneous intracerebral hemorrhage（SICH） in clinical experiments. Methods： The patients with SICH were given brain MRI T IWI, T2WI, DWI and T2^＊WI scans 1, 7 and 14 days after the stroke. The MRI images were recorded and analyzed by Image J software. Results： MRI T2^＊WI images of iron lesion were significantly clearer than other MRI scans. The lesion volume in T2^＊WI images was larger than that of T2W1 images 7 and 14 days after SICH （P〈0.05）. Conclusion： T2^＊WI are more clearer than other MRI scans and more sensitive than T2WI in the detection of iron lesion after SICH.
