Emailing a MR or CT study isn't a wise idea because the study may be tens or hundreds of megabytes and its n ot feasable to email it, however its doable.
I've developed a plugin for one of my customers that provides him with a WYSIWYG editor that he writes his report in it then add images from the ImaveViewer to it and email it as an RTF attachement to a specific Email address.
I can assist you in doing it, please email me the full details on wael_tahon at yahoo dot com.
