目的:分析肝脏局灶性结节增生的MSCT表现。方法:对9例患者10个病灶行MSCT平扫及动态增强扫描。结果:平扫病灶大多呈低密度灶,1例为等密度。增强动脉期病灶明显强化,部分病灶内可见星芒状瘢痕区及粗大供血动脉;门脉期及平衡期病灶密度降低,平衡期及延时期除一个病灶星芒征无明显变化外,其余均有强化。结论:典型的FNH诊断较容易,MSCT多期增强扫描在FNH的诊断中起重要作用,不典型病例需与肝癌、肝腺瘤、血管瘤等病变进行鉴别。
Objective: To analyze the MSCT manifestations of hepatic focal nodular hyperplasia. Methods: Ten lesions of 9 patients underwent MSCT scan and dynamic contrast-enhanced scan. Results: Most lesions showed low-density lesions, one case of equal density. Enhance the arterial phase lesions were significantly enhanced, part of the lesion visible stellate scar area and coarse feeding artery; portal phase and the balance of lesion density decreased, balance and delay except for a lesion Star sign was no significant change, the rest were Has strengthened. Conclusion: The typical diagnosis of FNH is relatively easy. MSCT multi-phase enhanced scan plays an important role in the diagnosis of FNH. Atypical cases need to be differentiated from liver cancer, hepatic adenoma and hemangioma.
