Re: Radiation levels - 64-slice CT vs. new 'dual-source' CT

James, thanks for your perspective. I do appreciate your opinion.

As for the actual equipment involved, the diverse answers about the
technology that's out there have been interesting albeit confusing.

When I called the hospital with the "dual-source" CT machines this
morning to ask about the difference between this version and the
"64-slice" CT, the Heart Center physician I spoke with
advised me that between the two, the radiation exposure is "about the
same."

Of course, this contradicts manufacturer information that suggests "up
to 50% lower" exposure
due to the different technology which is touted as an advantage of the
dual-source procedure.

I am now even more confounded in seeking an answer to what was really
my initial question which
was simply,
What's the difference in radiation between these two procedures?

Thanks again,

Mike


Mike,

What the doctor is saying is the level of radiation is so low that
there is no meaningful risk difference between the two methods. What
the equipment manufacturer is saying is advertisement and marketing
hype. Both are correct for different reasons. If I needed to undergo
the procedure I would simply follow my personal doctors suggestion.
You need to decide what makes you comfortable and science is not
necessarily the answer. For you the marketing stuff may be more
important.

Ask your doctor if it is ok to run. If he says yes go ahead. If he
says no I think it best to follow his advice. I sure would not follow
any advice from the internet on running or not running. No one here
has enough knowledge of your personal situation to make any rational
judgement. I would say that if your doctor says no and you run anyhow
you are accepting vastly more risk then you face from the minor
radiation exposure.
