目的：探讨三种非创伤性影像检查方法ＭＲＩ、ＣＴ和ＵＳ在肝癌诊断中的敏感性和准确性。方法：５２例经病理及临床证实的ＨＣＣ行ＭＲＩ，ＣＴ和ＵＳ检查。结果：ＭＲＩ常规序列与ＦＭＰＳＰＧＲ相比，敏感性以ＳＥＴ２Ｗ及ＦＭＰＳＰＧＲ序列为高。对ＨＣＣ检出总的敏感性依次为ＭＲＩ（ＳＥ＋ＦＭＰＳＰＧＲ）８５．８９％，ＣＴ７５．６４％，ＵＳ７１．７９％，＜３ｃｍＨＣＣ，ＭＲＩ检出的敏感性为７１．４２％明显高于ＣＴ（５１．４２％）和ＵＳ（４５．７１％），对于＞３ｃｍＨＣＣ，三者敏感性相似。ＨＣＣ定性准确性依次为动态增强ＦＭＰＳＰＧＲ（９２．０６％），常规ＳＥ序列（８５．９３％），ＣＴ（８４．７４％），ＵＳ（７５．００％），ＳＥ序列结合动态增强ＦＭＰＳＰＧＲ对肝癌定性准确性可达９５％，明显优于ＣＴ和ＵＳ。结论：在ＨＣＣ的检出敏感性和定性诊断上，１．５ＴＭＲＩＳＥ序列结合动态增强ＦＭＰＳＰＧＲ明显优于常规ＣＴ和ＵＳ，为肝癌重要的影像学检查手段。
Objective: To investigate the sensitivity and accuracy of three non-invasive imaging methods: MRI, CT, and US in the diagnosis of liver cancer. Methods: 52 cases of pathologically and clinically confirmed HCC were examined by MRI, CT and US. Results: Compared with FMPSPGR, the sensitivity of MRI routine sequence was higher with SET2W and FMPSPGR sequences. The total sensitivity to HCC detection was MRI (SE+FMPSPGR) 85.89%, CT75.64%, US71.79%, <3cmHCC, and the sensitivity detected by MRI was 71.42% was significantly higher than CT (51. 42%) and US (45.71%), for >3cm HCC, the three sensitivities are similar. The qualitative accuracy of HCC was dynamic enhanced FMPSPGR (92.06%), conventional SE sequence (85.93%), CT (84.74%), US (75.00%), SE sequence combined with dynamic enhanced FMPSPGR on liver cancer The qualitative accuracy is up to 95%, which is significantly better than CT and US. Conclusion: In the detection sensitivity and qualitative diagnosis of HCC, the 1.5TMRISE sequence combined with dynamic enhancement of FMPSPGR is significantly superior to conventional CT and US, and is an important imaging tool for liver cancer.
