目的探讨菲立磁增强磁共振在肝脏局灶性病变中的诊断价值。材料与方法对21例怀疑肝脏肿瘤的患者进行常规肝脏平扫和菲立磁增强扫描，分析增强前后T2WI检测病灶数目以及肝脏、病灶、脾脏信号强度的变化。结果菲立磁增强明显降低正常肝脏的信号强度，而病灶的信号强度无明显变化，病灶-肝脏的信号强度比增加；菲立磁增强可清晰地显示病变并可发现更多的病变。结论菲立磁增强在检测肝脏局灶性病变中敏感性高。“,”Objective To evaluate Feridex-enhanced MRI in the diagnosis of focal hepatic lesions. Materials and Methods Conventional plain and Feridex-enhanced MR scanning was performed in 21 cases with suspected hepatic neoplasm. The number of lesions on T2WI, and the signal intensity of liver, spleen and lesions demonstrated on plain and enhanced scans were observed and analyzed. Results After the injection of Feridex, the signal intensity of normal liver tissue reduced significantly, while the signal intensity of lesions showed no marked changes. Feidex-enhanced MRI clearly displayed more lesions on T2WI than plain scanning did. Conclusion Feridex-enhanced MRI is very sensitive in detecting focal hepatic lesions.
