【摘要】 目的探讨3种非创伤性影像检查方法超声(US)、CT和MRI在肝癌诊断中的敏感性和准确性,以提高对早期肝癌的影像诊断。方法回顾分析、比较79例肝癌的US、CT及MRI优缺点。结果肝癌确诊率为US:73.08%、CT:87.34%、MRI:87.76%。US对早期肝癌的检出率较高,但确诊率较低。CT和MRI对中晚期肝癌确诊率较高。结论US、CT、MRI各有特点,合理及综合利用,是提高早期肝癌诊断的关键。更多还原

【Abstract】 Objective To research sencitivity and accuracy of three kinds of nontraumatic image methods-US,CT and MRI,on hepatocarcinoma diagnosis,for improving image diagnostic rate on early hepatocarcinmoma. Methods 79 cases of hepatocarcinomas have been retrospectively analyzed and compared on US,CT and the MRI diagnosis. Results The accurate rates of heptacarcinoma using three image methods were US: 87.34%,CT:73.08% and MRI:87.76%,respectively.There was a higher detective rate for US diagnosis on early hepatocarcinomas,when a lower accurate rate.There were higher accurate tate for CT and MRI diagnosis on middle and late heptatocarcinoma.Conclusion Every method has its especial character.It is the key for improving early hepatocarcinoma diagnosis rate reasonable and comprehensive utilization of US,CT and MRI.更多还原
