摘　　要：目的探讨肝局灶性结节增生患者采用CT、磁共振成像(MRI)及超声造影诊断准确率及误诊率。方法回顾性选择本院于2017年4月至2019年4月期间收治的肝局灶性结节增生患者15例作为研究资料,均行CT、MRI检查,其中8例合并超声造影诊断,观察不同影像诊断技术的准确率、误诊率及影像特征。结果CT诊断病灶直径平均为(6.8±1.2)cm,准确率为40%(6/15)。MRI诊断直径平均为(6.8±1.3)cm,准确率为53%(8/15)。超声造影诊断直径平均为(6.8±1.2)cm,准确率为88%(7/8)。结论在肝局灶性结节增生患者诊断中加强对CT、MRI影像技术的应用虽然准确率较低,但可显示结节供血特征及病理特征,而配合超声造影诊断,则可提高准确率,为治疗提供可靠依据,值得推广。Objective To investigate the diagnostic accuracy and misdiagnosis rate of CT,MRI and contrast-enhanced ultrasound in patients with focal nodular hyperplasia of the liver.Methods 15 patients with focal nodular hyperplasia of the liver admitted to our hospital from April 2017 to April 2019 were retrospectively selected as the research data.All patients underwent CT and MRI examinations.Among them,8 patients were diagnosed by contrast-enhanced ultrasound.The accuracy,misdiagnosis rate and imaging characteristics of different imaging diagnostic techniques were observed.Results The average diameter of lesions diagnosed by CT was(6.8±1.2)cm,and the accuracy rate was 40%(6/15).The average diameter of MRI diagnosis was(6.8±1.3)cm,and the accuracy rate was 53%(8/15).The average diameter of contrast-enhanced ultrasound diagnosis was(6.8±1.2)cm,and the accuracy rate was 88%(7/8).Conclusion Although the accuracy of CT and MRI imaging is low,it can show the blood supply and pathological characteristics of nodules in the diagnosis of focal nodular hyperplasia of the liver.Combined with contrast-enhanced ultrasound diagnosis,it can improve the accuracy,provide reliable basis for treatment and is worth popularizing.
