超声弹性成像与超声造影在肝肿瘤定性诊断中的应用

摘要：目的探讨超声造影检查与超声弹性成像在肝肿瘤定性诊断中的价值。方法对61例患者的68个肝肿瘤病灶进行常规超声、超声造影及超声弹性成像检查。超声弹性成像采用5级评分法作为诊断标准:a、b诊断为良性,c~e级诊断为恶性,并与病理结果对照。结果常规超声诊断肝肿瘤良恶性的敏感度、特异度、准确率分别为79.59%、73.68%、77.94%;超声弹性成像诊断肝肿瘤的敏感度、特异度、准确率分别为89.79%、84.21%、88.24%;超声造影诊断肝肿瘤的敏感度、特异度、准确率分别为91.84%、89.47%、91.18%。弹性成像与超声造影诊断肝脏恶性肿瘤的准确率差异无统计学意义。结论超声弹性成像与超声造影检查相结合有助于提高肝肿瘤的检查敏感度和特异度,且具有互补作用。
Objective To observe the value of CEUS and ultrasonic elasticity(UE) imaging in differential diagnosis of malignant and benign hepatic tumors.Methods Sixty-one patients with 68 hepatic tumors underwent conventional ultrasound,CEUS and UE respectively.Five grades rating scale was used in UE as the diagnostic criteria: Grade a and b were diagnosed as benign tumors;Grade c to e were diagnosed as malignant tumors.All the results were compared with pathology.Results The sensitivity,specificity and accuracy in diagnosis of hepatic tumor with conventional ultrasound was 79.59%,73.68%,77.94%,while of UE was 89.79%,84.21%,88.24%,of CEUS was 91.84%,89.47%,91.18%,respectively.There was no difference between UE and CEUS.Conclusion Combined contrast-enhanced ultrasound with ultrasonic elasticity imaging can raise the sensitivity and specificity,and both methods have complementary effect in the differential diagnosis of malignant and benign hepatic tumors.
