[IPk] Re: MRI Scan

For those who asked, MRI and CT scans (brain or otherwise) are
generally shown in grey scale (i.e. black and white and shades of grey
in between). SPECT and PET scans are sometimes shown in colour, but it
really depends on the preference of the technicians and physicians at
the individual centre. Nowadays all these scans are digital, and it is
up to the individual physicians etc as to which sort of grey or colour
scale they believe is most helpful to them in interpreting the images -
generally most systems allow one to switch between different options,
and when they sit in front of the screen trying to make sense of your
images, they will certainly play with scales and windows, but may also
switch between grey scale and various colour schemes.
(whose chief professional interest is PET scans, but who gets to look
at SPECT, CT and MRI too for comparisons etc, and who prefers grey
scale, since although colours are pretty they can sometimes be
deceptive, leading you to believe there are smooth edges to structures
just because there is an arbitrarily set colour change there)
