目的比较超声造影与增强CT成像的特点及互补性,探讨超声造影对肝局灶性病变的诊断价值.方法对81个肝局灶性病变进行超声造影及增强CT检查,采用诊断评分分析两种方法的诊断价值与互补性,并评价病灶在不同成像方法中动脉期的表现.结果超声造影对肝局灶性病变的敏感性、特异性、阳性预测值、阴性预测值、准确性分别为96.6%,86.9%,94.9%,90.9%,93.8%,增强CT对应值分别为98.3%,82.6%,93.4%,95.0%,93.8%;两种影像检查分别误诊共6例,其中5例可通过两者结合互补作出正确诊断.25例肝转移瘤中超声造影动脉期18例(72%)表现为高血供,增强CT 8例(32%)表现为高血供,两者比较差异有统计学意义(P=0.040).结论超声造影和增强CT对肝局灶性病变均具有良好的诊断价值,二者有一定的互补性,转移瘤超声造影动脉期多血供表现的比例显著高于增强CT.

Objective To investigate the diagnostic value of contrast-enhanced ultrasound (CEUS), and compare it with contrast-enhanced CT(CECT). Methods Eighty-one focal liver lesions were evaluated with CEUS and CECT, diagnostic value of two modalities were calculated, vaseularity manifestations of two modalities in arterial phase were compared. Results The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CEUS were 96.6 %, 86.9 %, 94.9 %, 90.9 %, 93. 80%, respectively, and the diagnostic value of CECT were 98.3%, 82. 6%, 93.4%, 95.0%, 93.8%, respectively. Among all the metastasis, hypervascular manifestation lesions in arterial phase of CEUS and CECT were 72% (18/25) and 32% (8/25)( P <0.05). Conclusions The diagnostic value of CEUS and CECT in focal liver lesions are comparably satisfying,and there is no significant difference between them, the combination use of two modalities would improve the diagnosis performance. CEUS can show more hypervaseular metastasis than CECT in arterial phase.
