目的对比分析彩色多普勒血流图及能量图在肝癌诊断中的敏感性。方法采用彩色多普勒血流图及能量图的血流动力学及形态学改变对比分析102例肝癌病例,其中原发性(HCC)73例,继发性(MHC)29例。结果彩色多普勒血流图与能量图血流形态学对比改变明显高于彩色多普勒血流图形态学改变,应用两组3个类型,分别对比分析表明:①CDFI及CDE检测显示血流形态及血流动力学改变巨块型>结节型>弥漫型;②两种血流显像CDE优于CDFI,血流形态显示,血流随瘤体增大血流显示检出率增高;③肿瘤体增大其血流搏动指数(R I)、血流阻力指数(PI)随之增高,以结节型及巨块型增高为主。结论与中国医学影像技术中多普勒指数在小肝癌定性诊断中的应用结果相一致[1]。有待于对肝癌更进一步广泛应用、分析、诊断、鉴别诊断有很高的临床应用价值。
Objective To comparatively analyze the sensitivity of color Doppler flow chart and energy chart in the diagnosis of liver cancer. Methods A total of 102 cases of HCC were analyzed by color Doppler flowgraphy and the hemodynamics and morphological changes of energy maps. Among them, 73 cases were primary (HCC) and 29 were secondary (MHC). Results The color Doppler flow pattern and the energy pattern blood flow morphological changes were significantly higher than the color Doppler flow pattern morphological changes, the application of two groups of three types, respectively, comparative analysis showed that: ① CDFI and CDE test showed that blood flow Morphology and hemodynamic changes were massive> nodular> diffuse. ② CDE was superior to CDFI in both blood flow imaging. The blood flow pattern showed that blood flow increased with the increase of tumor volume. (3) The tumor increased the pulsatility index (RI), and the blood flow resistance index (PI) increased with the increase of nodules and bulky type. Conclusions and Chinese medical imaging Doppler index in the diagnosis of small liver cancer qualitative application of the results consistent [1]. To be further applied to liver cancer, analysis, diagnosis, differential diagnosis has a high clinical value.
