Hi DJ,
Sorry, had to ask what a xenon scan is. I'm looking it up as we speak.
Do you know if this is "standard" procedure, as I see you mentioned it as "annual follow-ups?"
(Just wondering if I should have one
...) From what I'm reading, it sounds like another great way to determine blood flow. Am I correct? I read in your Diagnostic process and questions for surgeons thread you mentioned that it is similar to a SPECT.
Do most have this done yearly?
"What's very nice about xenon CT is that it not only allows us to take a picture of the brain, as a traditional CT does, but it lets us exactly quantify how much blood flow is getting to different areas of the brain, and that's really been a mystery up until now," said Susan Hickenbottom, MD, a UM assistant neurology professor who heads the UM Health System's Stroke Program.
"Thirty days after their stroke and xenon CT scan, patients will receive another scan to see which areas of the brain were affected. By comparing the original scan with the second one, the researchers will be able to tell whether the initial scans can help them predict which areas will suffer most. Eventually, studies may compare xenon CT with other imaging techniques used in stroke patients, including a form of magnetic resonance imaging (MRI) and positron emission tomography (PET)."

Pretty interesting article..also touches on TPA. "One exciting new option is TPA, a clot-busting drug that can give many ischemic stroke patients a 30-50 percent better chance of walking away from the stroke unharmed." Then again, this may only pertain to regular type strokes and not specifically those associated with MM disease. Nonetheless, quite interesting to read.
Aloha,
