[摘要] 　目的　觀察肝腫瘤在超聲造影后的時相及回聲變化規(guī)律,并與增強CT對照,探討其對肝臟良惡性腫瘤的診斷價值。方法　59個肝臟占位性病灶, 采用新型造影劑SonoVne以及Technos DU8進行超聲造影研究。結果　17個原發(fā)肝癌病灶中13個表現(xiàn)典型的“快進快退”；2個表現(xiàn)為 “同進快退”；另2個表現(xiàn)為“快進慢退”。通過造影后的表現(xiàn)還可明確提示以下幾個方面：（1）腫塊內(nèi)的壞死區(qū)；（2）在延遲相發(fā)現(xiàn)了肝內(nèi)小轉移灶，從而改變了臨床治療方案；（3）滋養(yǎng)動脈的顯示；（4）門脈內(nèi)栓子的鑒別診斷。36個轉移性肝癌病灶分為少血供轉移癌組和多血供轉移癌組。6例肝血管瘤中5例均表現(xiàn)為向心性環(huán)行持續(xù)緩慢充填，另一例9mm的小血管瘤表現(xiàn)為完全、快速向心填充。造影增強后所測得腫塊大小,數(shù)量,和邊界均較常規(guī)超聲和增強CT有變化。結論　新型超聲造影技術可極大地提高超聲對肝臟占位病變的診斷價值。

[ Abstract] 　Objective 　To investigate the role of new real time gray-scale contrast tuned imaging in the diagnostic value of liver neoplasms . Methods 　Thirty one patients with unconfirmed liver neoplasms were studied. Results 　Among the seventeen cases of HCC ,Thirteen were typical. presented with early artery enhancement and immediate wash out ,Two cases presented with wash in quickly and wash out slowly .The enhancement pattern of 36 liver metastatics cases was divided into the little blood provides group and the much blood provides group . The 5 cases of haemangioma were enhanced centripetally in portal phase and washed out after several minutes without arterial enhancement. All liver neoplasms which after contrast enhanced were different from regular ultrasound and enhanced CT. Conclusion 　The new contrast ultrasound technique is sensitive and effective in diagnosing liver neoplasms.
