摘要
目的:评价菲立磁在增强磁共振T2WI在肝脏疑难病例中的应用价值。方法:选择15例经MRI平扫及普通增强检查有肝脏病变,但仍不能定性,需行菲立磁增强MR检查的患者,观测增强前后肝脏、病变及背景躁声的T2WI信号强度,计算增强前后肝脏、病变的信噪比(SNR)、对比噪音比(CNR)。观察菲立磁增强后病灶数目有无增加。结果:菲立磁增强后肝脏的SNR明显降低;恶性病灶的SNR变化不明显;病灶-肝脏CNR明显增高。菲立磁增强后病灶数目有明显增加。结论:菲立磁能够显著提高工作效率肝脏恶性肿瘤的确诊率及检出率,并且对小肝癌及肝硬化小结节的鉴别诊断提供有利的依据。
Objective： To evaluate feridex （superparamagnetic iron oxide, SPIO） enhanced MRI in the diagnosis of liver difficulty application in the case value. Methods： 15 examples were tested through the MRI, even scan and common enhanced check, there were liver pathological changes, but term background noise for T2WI signal for patient was not stable, still the feridex enhanced MRI check was needed, prognosticating signal strength of liver pathological changes and background noise before and after, calculating pathological changes ratio （SNR） and contrast noise ratio （CNR）. Before and after liver enhanced, after the feridex enhanced, the disease cooking storing number which increased or not was observed. Results： after the feridex enhanced, the SNR of liver was obviously lower, the SNR change of the malignant disease cooking stove was not significant, disease cooking stove-liver the CNR obviously increased. The disease cooking stove number after feridex enhanced increased greatly. Conclusion： The feridex enhanced MRI can really prove the work efficiency, the diagnostic rate and finding outs rate of liver malignant tumor, it is beneficial for diagnosis of small cancer of the liver and cirrhosis the authenticate of stanza sub-footing.
