I have measured the mean diameter of a series of vascular lumina by
measuring the area of their lumen first. Then, assuming this as a perfect
circle, I have calculated the diameter for each. This method removes the
subjectivity of selecting an arbitrary line as the diameter. If your vessels
look physically "compressed", you can probably use the "perimeter" as a
starting point to calculate the diameter. (Assuming this perimeter as one of
a circle, and then...)
I can supply the simple macro I have prepared for this (from area to
radius).  However, I am sure there are better ways of doing your
measurement...
