彩色多普勒血流显像对肝占位的诊断价值

DIAGNOSTIC VALUE OF COLOR DOPPLER FLOW IMAGING FOR HEPATIC SPACE-OCCUPYING LESIONS

本文报告运用彩色多普勒血流显像检查了４８例肝占位性病变，全部经ＡＦＰ、ＣＴ扫描、Ｂ超检查确诊。本组２５例原发性肝癌中，肝动脉增粗、肿瘤内动脉血流、肿瘤周围血流包绕分别为４０％（１０／２５）、９２％（２３／２５）、９６％（２４／２５）。与其他肝占位性病变（转移癌、血管瘤、肝囊肿、肝脓肿）进行对比分析，后者肿块内无动脉血流。因此，彩色多普勒血流显像对于提高原发性肝癌诊断有很高的特异性。本文还就其局限性进行讨论。

The hepatice space-oceupying lesions were studied with color Doppler flow imaging(CDFI) in 48 patients. All were confirmed by AFP. CT and B-mode ultrasound examination. In the patients with primary hepatic carcinomas,there were hepatic artery dilatation,arterial flow within the tumors,and flow around the tumors.The detection rate was 40%(10/25),92%(23/25)and 96%(24/25) respectively.Since in other hepatic space-oceupying lesions (metastases, hematomas,cysts,abscesses),there were no arterial flow in the mass,COFI has obvious specificity for primary hepatic careinomas diagnosis.The limitations of CDFI are also discussed in this article.
