摘　　要：目的:分析肝硬化再生结节与小肝癌结节的影像学特征。方法:回顾性分析2020年6月—2023年6月贺州市人民医院收治的66例肝硬化患者的影像学资料,探讨肝硬化再生结节与小肝癌结节的影像学特征。结果:磁共振成像-弥散加权成像(MRI-DWI)扫描发现,肝硬化再生结节组患者平均病灶大小、表观弥散系数(ADC)均高于小肝癌结节组,差异均具有统计学意义(t=6.903、5.593,P<0.05);肝硬化再生结节组T_(1)WI稍高信号及等信号呈现率高于小肝癌结节组(χ^(2)=12.158、10.627,P<0.05),等信号或低信号呈现率则低于小肝癌结节组(χ^(2)=31.611,P<0.05);肝硬化再生结节组T_(2)WI低信号呈现率高于小肝癌结节组,等信号、高信号或稍高信号呈现率低于小肝癌结节组,差异具有统计学意义(χ^(2)=54.393,P<0.05)。结论:磁共振成像能够更好地鉴别出肝硬化再生结节与小肝癌结节,提高早期肝癌的诊断率。Objective The imaging features of cirrhotic regenerative nodules and small hepatic carcinoma nodules were analyzed.Methods The imaging data of 66 patients with liver cirrhosis admitted to Hezhou People's Hospital from June 2020 to June 2023were selected to explore the imaging features of regenerative nodules and small hepatic carcinoma nodules in liver cirrhosis.Results Magnetic resonance imaging-diffusion-weighted imaging(MRI-DWI) scan showed that the average lesion size and the apparent diffusion coefficient(ADC)of the cirrhotic regenerative nodule group were higher than those of the small hepatic carcinoma nodule group,and the differences were statisticallu significant(t=6.903,5.593,P<0.05);the rate of the slightly high signal and equal signal of T_(1)WI in cirrhosis regenerative nodule group was higher than that in small hepatic carcinoma nodule group(χ^(2)=12.158,10.627,P<0.05),and the presentation rate of equal signal or low signal was lower than that of small hepatic carcinoma nodule group(χ^(2)=31.611,P<0.05).The low signal presenntation rate of T_(2)WI in the cirrhosis regenerative nodule group was higher than that in the small hepatic carcinoma nodule group,and the equal signal,high signal,or slightly high signal presentation rate was lower than that in the small hepatic carcinoma nodule group,and the differences were statistically significant(χ^(2)=54.393,P<0.05).Conclusion Magnetic resonance imaging can better identify cirrhotic regenerative nodules and small hepatic carcinoma nodules.and improve the diagnosis rate of early hepatic carcinoma.
