I doubt readers of this site have any medical advice to offer. I can talk about how DTI works (the physics), but not about its clinical utility for any particular patient. I do know that the <a href="http://www.epilepsynse.org.uk/pages/contact/index/" rel="nofollow">National Society for Epilespy</a> may use MRI scanning on patients to see what is happening during an episode, but I can't say whether this is clinically relevant to your partner. Most hospitals have MRI scanners these days, but not all do DTI. It would be best to discuss with your partner's consultant whether DTI is relevant for his condition, before contacting MRI sites directly. Sorry I can't be of more help. Dave Hi Ruth,

My partner is 45yrs of age and for the past 20yrs roughly has suffered what consultants feel is a form of epilepsy. His symptoms present with disorientation and confusion,sweating,panicky disturbance with sleep and twitching to name some. As a early teenager he had been sent to a few children's centres for a few months at a time for his behaviour. He became addicted to glue around that time and continued sniffing for around 7yrs. His early twenties is when he first started developing his condition. It was apparently either just prior or after that he found his favourite uncle dead. He continued to have these episodes which eventually were becoming more often and lasting longer. He is currently coming out of one that he has been in for just short of 3 weeks. In the past sometimes it has just been a day but that was going back about 2yrs ago. Due to his condition, when his mother died he felt unable to attend the funeral which was about 16yrs ago. Roughly 2yrs ago whilst living at home with his father, he returned home from a evening out and found his father dead. The reason I am giving you this background information,is that when he has an episode he often not knowingly will speak aloud or a incoherent jargon and the understandable dialogue he is remembering father etc and feels his father, uncle are not dead. He has had numerous EEG's and a couple of MRI's which have not detected any abnormality. He throughout the years has been prescribed various AED's and anti-pyschotic medications but continues to suffer he seems resistant to the medication. Do you think suggesting to his consultant a DTI scan,and if so we live in South Wales, UK where would be the nearest DTI centre or have you perhaps heard of similar cases? I would be most grateful for any information as his quality of life and ours as a couple is greatly affected,especially due to the frequency(last one being nine weeks ago till this one)and length of time of his seizure/episode? Many thanks in anticipation. I hope you may be able to help, after a lot of research I have come by DTI on the net and there after have found this site.

Upon installation (you have to love the package management of ubuntu), it takes some CPU time out to index your whole lot but it is blazingly quick later when you search for stuff and sorts it into categories.

Erik Magnus Lensher's comment about "too much iron in your blood" could have meant to be witty, obviously the creators knew that he couldn't work with the normal iron. In one of the comics, Magneto did kill someone by removing their pace-maker though. Ah, but who says the iron was truly dissolved into the man’s blood?
