彩色多普勒超声在肝脏占位性病变中的诊断价值

目的探讨彩色多普勒超声在肝脏占位性病变诊断中的临床价值。方法对62例经CT或者病理检查证实的肝脏占位性病变患者（其中原发性肝癌的18例,转移性肝癌14例,肝血管瘤22例,肝硬化增生结节8例）采用彩色多普勒超声进行检查。结果原发性和转移性肝癌患者血流灌注指数（DPI）、阻力比（RR）值均显著高于肝血管瘤以及肝硬化增生结节患者（P〈0.05）,肝硬化增生结节患者门静脉充血指数（PCI）、肝总血流量（TLBF）值均显著高于其他肝脏占位性病变患者（P〈0.05）。结论彩色多普勒超声可提供多个血流参数指标,显著提高对肝脏占位性病变的诊断和鉴别水平。

Diagnostic Value of Color Doppler Ultrasound in Space-occupying Lesion in Liver

Objective To discuss the diagnostic value of color Doppler ultrasound in space-occupying lesion in the liver.Methods Color Doppler ultrasound was performed in 62 cases of liver space-occupying lesion diagnosed by CT or pathological examination,including 18 cases of primary hepatic carcinoma,14 cases of metastatic hepatic carcinoma,22 cases of hepatic hemangioma,and 8 cases of hyperplastic nodules in cirrhotic liver.Results Compared with patients with hepatic hemangioma or hyperplastic nodules in cirrhotic liver,Doppler perfusion index and resistance ratio index significantly increased in patients with primary hepatic carcinoma or metastatic hepatic carcinoma（P0.05）.Compared with patients with space-occupying lesion in the liver,total liver blood flow and portal congestive index obviously increased in patients with hyperplastic nodules in cirrhotic liver（P0.05）.Conclusion Color Doppler flow imaging can provide multi-parameters and improve the diagnosis and identification of space-occupying lesion in the liver.
