目的 :探讨菲立磁增强MRI对肝肿瘤的检出和定性方面的应用价值。方法 :对 12例临床诊断为肝肿瘤的患者行MRI平扫及菲立磁增强扫描 (均包含T1WI及T2 WI) ,分析其MRI平扫、菲立磁增强MRI图像对病灶的显示情况 (包括病灶数目、大小、病灶边界显示的清晰度等 )及病灶定性的准确性。结果 :MRI平扫共检出病灶 6 3个 ,而菲立磁增强MRI共检出病灶 118个 ,对病灶的显示较平扫MRI更为清晰 ,发现病灶的最小直径仅 3mm左右 ;菲立磁增强MRI结合平扫MRI均作出了准确的定性诊断 ,其中包括原发性肝癌 5例 ,转移性肝癌 3例 ,肝血管瘤 2例 ,肝囊肿 2例。结论 :菲立磁增强MRI在肝肿瘤 (尤其是直径 1cm以下的小病灶 )的检出和定性方面具有较大的临床应用价值。
Objective: To investigate the application of Feridex enhanced MRI in detection and characterization of liver tumors. Methods: Twenty-two patients with clinically diagnosed liver tumor underwent plain MRI and enhanced MRI (all included T1WI and T2WI). The MRI findings of the lesion were analyzed by MRI (including The number of lesions, the size, the clarity of the lesion boundaries, etc.) and the qualitative accuracy of the lesions. Results: Sixty-three lesions were detected by plain MRI, while 118 lesions were detected by Feridex enhanced MRI. The lesion showed more clearly than the plain MRI, and the smallest diameter of lesion was only about 3 mm. Enhanced MRI combined with plain MRI have made accurate qualitative diagnosis, including 5 cases of primary liver cancer, 3 cases of metastatic liver cancer, 2 cases of hepatic hemangioma and 2 cases of hepatic cyst. Conclusion: Feridex enhanced MRI has great clinical value in the detection and characterization of liver tumors (especially small lesions less than 1 cm in diameter).
