cost effectiveness, page-5

Gmutton, I emailed Prof G Kelly of Novogen some time back with a question, I asked him if it was possible to use CLE to help with brain surgery?
My question was that if they were working in that area where a tumor was being removed, then would it be possible to use CLE to define just where the cancer started and where normal cells existed and if this was possible then a drug could be delivered to exactly where it needed to be, he didn't respond to my email, which was not normal, because he is very good at answering questions normally from shareholders?
A short time later there was a shareholder release by Novogen and in that release there was mention of using confocal imagery to help deliver drugs to where they were needed, I now believe my question was way too close to the mark for Prof Kelly to answer me?
My question is this if they were going to use this method for drug delivery, wouldn't they use the best available?
Maybe me mentioning Optiscan was way too close to the mark as I said?
