| 摘 要： | 目的探讨MR薄层多期增强扫描对肝脏局灶性结节增生(FNH)的诊断价值。方法回顾性分析13例经病理证实的肝脏FNH的MRI表现。结果 13例病灶平扫均呈T1WI稍低信号,T2WI稍高信号;增强扫描除中央瘢痕外,病灶动脉期明显强化,门脉期呈稍高信号,延迟期呈稍高或近等信号,11例病灶的中央瘢痕延迟强化。结论 MR薄层多期增强扫描对肝脏FNH的诊断具有特异性和准确性,结合临床检查能大大提高FNH的诊断率。

| Abstract: | Objective To assess the value of multiphasic contrast-enhanced MR in diagnosing focal nodular hyperplasia(FNH). Methods The MRI manifestations in 13 patients with pathologically confirmed FNH were reviewed retrospectively.Results On plain scan,the focus showed low signal on T1WI and slightly high signal on T2WI.On postconstrast MRI showed intense enhancement of the focus at arterial phase,except central scars.At portal vein phase,the lesion signal showed slightly higher,and at delayed phase,the lesion showe... |
