肝癌彩色超声、CT增强的影像检查探讨

Imaging characteristics of liver cancer with color doppler blood flow imaging and CT enhanced scan

目的探讨肝癌的彩色超声(彩超)、CT增强两种影像方法的特征。方法回顾分析50例原发性肝癌和50例转移性肝癌患者彩超及CT增强表现 ,并与手术、病理或临床随访相对照。结果彩超检测肝癌 :原发性肝癌以瘤内点状、条状搏动性血流居多 ,转移性肝癌以瘤周点状、条状血流居多。CT增强检测肝癌 :原发性肝癌以快进快出为主要表现 ,转移性肝癌以周边部不规则强化为主要表现。结论彩超、CT增强可帮助分析肝癌的血供情况 ,两者联合使用 。

Objective Through analysis imaging of liver cancer with CDFI and CT enhanced scan,study imaging characteristic of liver cancer with the two methods. Methods Patterns of blood flow supply of 50 cases with hepatocellular carcinoma and 50 cases with liver metastatic cancer were reviewed by color doppler flow imaging and CT enhanced scan imaging. Their results were compared with surgery, pathology and long term following up. Results Diagnosis of liver cancer with color doppler imaging: the shape of dot or band and pulsatoy blood flow signals with the tumor were observed in HCC, the lesions of LMC showed mainly periphery flow pattern around tumor. Diagnosis of liver cancer with CT enhanced scan: the enhancememt imaging about the lesions of HCC showed mainly fast to top, then fast to bottom; the lesions of LMC showed mainly periphery irregular enhancement. Conclusion Color doppler flow imaging and CT enhanced scan can improve analysis of the flow of liver cancer.Combination of the two methods can improve diagnosis of liver cancer.
