摘要
目的：探讨原发性肝癌在低场ＭＲ不同序列上的表现并进行比较。方法：原发性肝癌３６例，以ＳＥ。（普通ＳＥ）、ＳＥ２（快速ＳＥ）序列成像，部分加作ＩＲ序列及ＦＥ序列。结果：在Ｔ１－ＷＩ上肝癌主要表现为均匀的等或略低信号，以等信号居多。在Ｔ２－ＷＩ上则表现为不均匀的高信号，且其强度随ＴＥ延长而衰减。在ＩＲ序列上肝癌则主要表现为均匀的高信号，其强度低于Ｔ２－ＷＩ，并有随ＴＩ延长而增强的趋势。结论：ＳＥ２Ｔ２－ＷＩ与ＩＲ序列的联合使用是肝癌检查和诊断的最佳序列组合。
—玂bjective:To study and compare the signal character of primary hepatic carcinoma (PHC) on different sequences of low field MR.Methods:36 cases of PHC were studied, one part was imaged with SE0,SE2,IR,FE sequences,another with SE0,SE2 sequences.Results:PHC was homogeneous isointense or slightly hypointense on SE T1-WI,and the diagnosis was based on the change of vascular structure and hepatic form.On SE T2-WI,most of tumors were unhomogeneous hyperintense,and the signal intensity decreased when the TE prolonged.On IR sequence,the lesions were homogeneous hyperintense,the signal intensity was lower than that on T2-WI,and the longer the TI,the higher the signal intensity.Conclusion:The combined use of SE2 T2-WI and IR sequence is the best sequence combination in diagnosis of PHC.
