超聲彈性成像與超聲造影在肝腫瘤定性診斷中的應(yīng)用

摘要：目的探討超聲造影檢查與超聲彈性成像在肝腫瘤定性診斷中的價(jià)值。方法對61例患者的68個(gè)肝腫瘤病灶進(jìn)行常規(guī)超聲、超聲造影及超聲彈性成像檢查。超聲彈性成像采用5級評分法作為診斷標(biāo)準(zhǔn):a、b診斷為良性,c~e級診斷為惡性,并與病理結(jié)果對照。結(jié)果常規(guī)超聲診斷肝腫瘤良惡性的敏感度、特異度、準(zhǔn)確率分別為79.59%、73.68%、77.94%;超聲彈性成像診斷肝腫瘤的敏感度、特異度、準(zhǔn)確率分別為89.79%、84.21%、88.24%;超聲造影診斷肝腫瘤的敏感度、特異度、準(zhǔn)確率分別為91.84%、89.47%、91.18%。彈性成像與超聲造影診斷肝臟惡性腫瘤的準(zhǔn)確率差異無統(tǒng)計(jì)學(xué)意義。結(jié)論超聲彈性成像與超聲造影檢查相結(jié)合有助于提高肝腫瘤的檢查敏感度和特異度,且具有互補(bǔ)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.
