目的 探討實(shí)時(shí)超聲造影檢測(cè)和診斷體積較小原發(fā)性肝癌的價(jià)值。
方法 分析353例共378個(gè)經(jīng)臨床和病理檢查證實(shí)的直徑≤3 cm的原發(fā)性肝癌的超聲造影表現(xiàn),包括造影的增強(qiáng)時(shí)相和增強(qiáng)方式,并與病理類型相比較。
結(jié)果 所有原發(fā)性肝癌中96.6%(365/378)的病灶動(dòng)脈相顯示增強(qiáng),其中 317(83.9%)個(gè)病灶增強(qiáng)早于肝實(shí)質(zhì),48(12.7%)個(gè)病灶增強(qiáng)與肝實(shí)質(zhì)同步; 增強(qiáng)方式中329(87.0%)個(gè)病灶呈整體增強(qiáng),35(9.3%)個(gè)呈斑片狀增強(qiáng),14(3.7%)個(gè)病灶呈環(huán)狀增強(qiáng)。在門脈相和晚期相,342(90.5%)個(gè)病灶相對(duì)于肝實(shí)質(zhì)呈低回聲。若將造影時(shí)病灶動(dòng)脈相增強(qiáng)早于或同步于肝實(shí)質(zhì)以及門脈期消退作為超聲造影診斷肝癌的標(biāo)準(zhǔn),則敏感性為87.3% (330/378); 若將整體增強(qiáng)和斑片狀增強(qiáng)作為原發(fā)性肝癌的特異增強(qiáng)方式,結(jié)合增強(qiáng)方式和時(shí)相,則超聲造影鑒別診斷原發(fā)性肝癌的敏感性為92.9%(351/378)。
結(jié)論 超聲造影可實(shí)時(shí)動(dòng)態(tài)觀察肝腫瘤相對(duì)于肝實(shí)質(zhì)的灌注和廓清過(guò)程,揭示腫瘤的血流動(dòng)力學(xué),在鑒別診斷小肝癌中具有重要的臨床實(shí)用價(jià)值。
