Mri - General Interest Query Posted: 10-13-06 14:43pm
Forgive me if i'm wtrong but I am merely a
dabbler in this field, general interest in
medicine that I could never satisfy due to
not being good enough to fix people, just
to fix aircraft. By my understanding an
mri? Image works from the minor metallic
elements in the blood (chiefly iron) so
how does this work on patients with
depleted blood iron content i.E anaemia?
Just a point of intellectual curiosity, I
would be grateful for any response,
especially if I have any misconceptions
that can be corrected.

Mri gets its images from resonating
hydrogen atoms, not iron. How anemia
affects the image i'm not quite sure. Any
magnetically charged or attracted metals
will be pulled by the mrmachine's force
though. I'm guessing that iron in the
blood is in such tiny particles that it
doesnt effect the image at all.
