| 目的 探讨灰阶超声造影成像(CE-GUS)诊断肝占位性病变的应用价值。方法 应用CPS及AD-CCI成像技术检查39个肝脏局灶性病变,32个病灶同期检查基波彩色多普勒增强超声(CE-CDFI)。 结果 CE-GUS病灶内部血流信号显示率97.44%,高于CE-CDFI(P<0.05)。CE-GUS诊断符合率为92.3%(36/39),明显高于常规超声检查(23.1%)及CE-CDFI(50%),P<0.05。结论 CPS及CCI灰阶超声造影成像技术能清楚显示肝脏及肝肿瘤血液灌注,对肝脏局灶性病变的鉴别诊断有实用价值。 |

| Objective To study the value of contrast enhanced harmonic gray-scale ultrasonography (CE-GUS) in the differentiation of focal hepatic lesions. Methods Thirty-nine solid focal lesions were examined by using contrast pulse sequencing (CPS) and coherent contrast imaging (CCI) imaging technique with SonoVue enhanced ultrasonography. Thirty-two lesions were also examined with contrast enhanced fundamental color Doppler imaging (CE-CDFI). Results The blood flow signal within lesions visualized by grey-scale contrast enhanced ultrasonography (CE-GUS, 97.44%) was significantly higher than that of result with CE-CDFI (P<0.05). The positive diagnoses with CE-GUS according to the characteristic and dynamic enhancement (92.3%, 36/39) was significantly higher than that of conventional ultrasound (23.1%) as well as CE-CDFI (50%), P<0.05. Conclusion CPS and CCI, the contrast enhanced grey-scale ultrasonography technique, were useful for visualization of tissue perfusion and differentiation diagnosis for hepatic focal lesions. |
