彩色多普勒诊断小肝血管瘤与小肝癌之评价

Evaluation of Color Doppler Flow Imaging in Diagnosis of Small Hepatic Cavernous Hemoangioma

本文收集本院91年10月至94年12月住院病人由彩超检查,并经手术及病理证实的20例小肝血管瘤及17例其他肝的小占位病变,其中小肝癌7例。小肝血管瘤内部及边缘的搏动性频谱检出率明显低于小肝癌,而动脉阻力指数显著低于小肝癌。彩色多普勒对小肝血管瘤的诊断是可靠的方法。

Twenty patients with small hepatic cavernous hemoangioma(SHCH) confirmed his-tologically and 17 patients with other small hepatic occupied lesions, diagnosed surgically and pathologically,were studied with color Doppler flow imaging( CDFI) from October 1991 to December 1994 in the hospital. The ultrasonied graph of arterial flow within the tumor and in the peripherol side were markedly lower than in HCC cases. The arterial resistent index SHCH was signekcantly lower than 50% . Therefore CDFI is a noninvansive, convenient and sensitive method for diagnosis of SHCH.
