目的提高对肝脏局灶性结节增生(FNH)CT表现的认识,探讨多层螺旋CT的诊断价值。方法对21例经手术病理证实的FNH的CT表现进行回顾性分析。结果18例为单发病灶,3例为2个病灶。CT平扫22个病灶呈低密度,2个为等密度。CT强化特点:病灶动脉期快速显著增强而门静脉期及延迟扫描为等密度,22个病灶检出瘢痕。结论多层螺旋CT多期增强扫描能显示FNH的增强特征性改变。
Objective To improve the understanding of the CT findings of focal nodular hyperplasia (FNH) in the liver and to explore the diagnostic value of multi-slice spiral CT. Methods The CT findings of 21 cases of FNH confirmed by surgery and pathology were retrospectively analyzed. Results 18 cases of single lesions, 3 cases of 2 lesions. Twenty-two lesions of CT scan showed low density and two of them were equal density. CT enhanced features: rapid significant increase in the arterial phase of the lesion and portal vein and delayed scan for the same density, 22 lesions were detected scar. Conclusion Multislice spiral CT multi-phase enhanced scan can show the enhanced characteristic changes of FNH.
