I haven't read the articles yet (I will this weekend) but I will say that
one of the neuroradiology folks here mentioned that it is actually is
important to do your scans on the same kind of machine (manufacturer and
tesla) with the same imaging protocol (if at all possible). In this way, the
electronic files can be directly compared. There are very slight differences
between the different vendor machines, and slight differences in the image
protocols they use. I even found that an imaging protocol for the same
scanner vendor may have one result on a 1.5t MRI and/or a 3t MRI. A lower
resolution scanner (measured in tesla e.g. .4tesla) may not pick up fine
details, and an open MRI is often a lower tesla and may also not be able to
pick up the fine details. Another thing my doctor told me that some
radiologists and even neuroradiologists may not be very good at reading
pituitary images. This explained to me why for 3 years straight, my scans
were always read as "normal", but when I met with the neurosurgeon, he
pointed out my microadenoma plain as day. It wasn't until I had imaging done
at a major pituitary center, did the radiologist actually note my tumor in
my report. The thing that interested me was that on the 1.5t scanner, the
interpretation of the films was a 4mm tumor on the right, and with the 3t
scanner (same manufacturer), the 3mm tumor was on the left.
I got a chuckle when I read the surgeon's report and the 5mm tumor was
predominately on the right, but there was some extention into the left of
the gland (took a human eye/microscope to sort it out ;) )
Thanks for sharing...just thought I'd add (and hopefully didn't stick my
foot in my mouth before I read the articles!).
