摘　　要：目的 研究菲立磁增强磁共振在肝脏局灶性病灶中的灵敏性和特异性。方法 对54例临床或其他检查怀疑肝脏占位病变的病人进行平扫、菲立磁增强扫描,分析增强前后图像上病灶和肝脏的信号强度的变化。结果 平扫T2W像上,原发性肝癌和肝转移瘤信号稍高于肝脏或为中等信号。肝硬化再生结节为等信号或稍低信号。菲立磁增强后原发性肝癌和转移瘤显示为中等或明显高信号;肝硬化再生结节仍显示为等或低信号。结论 菲立磁增强磁共振对肝脏局灶性病变有较高的特异性和敏感性。To study the sensitivity and specificity of MRI enhanced by feridex in the diagnosis of focal hepatic lesions. Methods The MR plain scan and feridex enhanced scan were performed in 54 patients who was suspected hepatic occupying lesions by clinical and other laboratory examination.The change of imaging focus and intensity of hepatic signal were analized in all cases before and after enhancement.Results On imag-ing with plain scans T2W,the lesions of primary hepatic cellular carcinoma and metastatic lesions showed a high or middle intensity,while the regenerative nodules in cirrhosis appeared iso- or slight hypo-intensity. On en-hanced imaging with feridex, primary hepatic cellular carcioma and metastatic lesions showed moderate or obvi-ous high intensity, while the regenerative nodules still showed iso- or hypo-intensity.Conclusion The MRI en-hanced by feridex have a higher sensitivity and specificity in the diagnosis of focal hepatic lesions.
