Verify image structure blocks Espionage image mount

Hello,
as I have important information on the images created by Espionage, I wanted to verify permissions and structure of the images.
I used Apple DiskUtility to do it. It founded structure problems on some of the images (SyncService was one of them). After the check, I realized the images were unmounted and after that, they were impossible to be mounted again (using either the Espionage menu or the app).
I needed to reboot to be able to mount the volumes again.
Is it ok to verify disk the images using the Apple Disk Utility?
Anything I can do to solve this issue?
Regards.
