Are the Terms "Let Him be Anathema" and "Excommunicated" Synonymous?

In the Douay Rheims, Galatians 1:6-8, for example, we read: >**6** I wonder that you are so soon removed from him that called you into the grace of Christ, unto another gospel. **7** Which is not another, only there are some that trouble you, and would pervert the gospel of Christ. **8** But though we, or an angel from heaven, preach a gospel to you besides that which we have preached to you, let him be anathema. And, for example, the Council of Trent promulgated a list of "excommunicable offenses" according to Wikipedia's [List of excommunicable offences from the Council of Trent](https://en.wikipedia.org/wiki/List_of_excommunicable_offences_from_the_Council_of_Trent) , all of which conclude with "let him be anathema". According to Catholic Teaching, are the terms "let him be anathema" and "excommunicated" synonymous?
