[摘要] 目的 探討超聲造影在肝硬化基礎(chǔ)上低度和高度不典型增生結(jié)節(jié)的表現(xiàn)。 方法 對(duì)本院2009年6月～2011年6月經(jīng)病理確診的17個(gè)低度和20個(gè)高度不典型增生結(jié)節(jié)患者的二維超聲和超聲造影檢查資料進(jìn)行回顧性分析，觀測指標(biāo)為病灶的大小、回聲、邊界、聲暈及血供。 結(jié)果 超聲造影顯示低度不典型增生結(jié)節(jié)(LGDN)和高度不典型增生結(jié)節(jié)(HGDN)在動(dòng)脈期、門脈期、延遲期表現(xiàn)無明顯差異，差異無統(tǒng)計(jì)學(xué)意義(P > 0.05)。 結(jié)論 超聲造影在肝硬化基礎(chǔ)上低度和高度不典型增生結(jié)節(jié)的表現(xiàn)相似；對(duì)LGDN與HGDN只有通過穿刺病理檢查確診，但通過超聲造影的三期表現(xiàn)及各期增強(qiáng)水平表現(xiàn)，可以反映出肝臟不同的血供變化，對(duì)肝細(xì)胞癌的早期診斷提供幫助。

[Abstract] Objective To investigate the features of enhanced contrast ultrasound imaging results of low-grade dysplastic nodules (LGDN) and high-grade dysplastic nodules(HGDN) in liver cirrhosis. Methods Two-dimensional ultrasound and ultrasonic imaging data of 17 low-grade dysplastic nodules patients and 20 high-grade dysplastic nodules patients were analyzed retrospectively. The patients were pathologically confirmed in the author's hospital from June 2009 to June 2011, and the lesion size, reverberation, boundary, sound dizzy and blood supply were observed. Results Ultrasound imaging showed no significant differences between low-grade dysplastic nodules and high-grade dysplastic nodules at arterial phase, portal phase and delayed phase (P > 0.05). Conclusion Ultrasound imaging of low-grade dysplastic nodules and high-grade dysplastic nodules in cirrhosis are of similar features; low-grade dysplastic nodules and high-grade dysplastic nodules can be diagnosed only by biopsy, but the three-phase enhanced performance ultrasound imaging can show the different blood supply changes in the liver, thus is helpful for the early diagnosis of hepatocellular carcinoma.
