【摘要】 目的对比分析超声造影(CEUS)和增强CT(CECT)显示肝脏恶性肿瘤的血流灌注特点,探讨超声造影的临床应用价值.方法102例患者接受了超声造影和增强CT检查,并与手术或穿刺活检病理结果比较,评估其诊断价值.结果超声造影诊断准确率达96.1%,增强CT诊断准确率95.1%,两者比较差异无显著意义(P>0.05).超声造影显示最小病灶为0.7cm,增强CT显示最小病灶为1.0cm.原发性肝癌瘤内供血血管的显示两者比较差异有显著意义(P<0.05),其中超声造影显示供血血管的病灶43例,增强CT显示18例.结论超声造影和增强CT对肝脏恶性肿瘤的诊断均有较高的准确率,对一些特殊肝脏肿瘤患者,联合检测可提高早期诊断的检出率;超声造影对微小病灶及瘤内供血血管的显示优于增强CT,可更好地反映肿瘤组织新生血管灌注特点,对评估肿瘤血管生成状况提供信息.更多还原

【Abstract】 Objective Tocomparativelyanalyze the perfusion features ofliver malignant tumors with CEUS and CECT and evaluate the clinical application value of CEUS.Methods 102 patients underwent examination of CEUS and CECT.The diagnostic value was evaluated by comparing its outcome with operation or pathological results of biopsy.Results The diagnostic accuracy rate of CEUS and CECT was 96.1% and 95.1%.Two methods had no significant difference (P>0.05).The smallest liver malignant tumors examined with CEUS and CECT was 0.7 cm and 1.2 cm.CEUS and CECT had significant difference in 46 patients primary liver carcinoma of in intratumoral donating blood vessels display (P<0.05).The donating blood vessels was displayed in 43 lesions on CEUS and 18 on CECT.Conclusions Both CEUS and CECT have high diagnostic accuracy rate.But for some unusual patients with liver malignant tumors,the combination should improve the early diagnostic ratio.CEUS was superior to CECT in display donating blood vessels,especial in finding smaller lesions.It can reflect the perfusion features of new grow vascular of tumors and provide information in evaluation angiogenesis of tumors.更多还原
