Problem to open a file of MDF format . need help

I had a problem. While working in MS SQL Server was made to emergency restart the computer. After reboot tried again to run the file, but nothing happened. There is a possibility of damage to the database, the program marks the file base in gray. The format of the file is mdf. What to do? Is it possible to get well?
