How do I update a struct array in a for loop?

I am determining the equivalent diameter of circles in a series of images.
My code is as follows:
for k = 1:20
I = imread(k);
BW = im2bw(I);
stats = regionprops(BW,'EquivDiameter');
end
I would like the stats struct array to update the values so I get a summary of all the analyzed equivalent diameters, instead of just the last image which is what my code is giving me now. Any ideas?
Thanks,
Mark

@Mark Lepage: if the data within C all have suitable sizes, you can certainly concatenate it into one structure afterwards:
cat(N,C{:}) % pick N for the dimension to concatenate along
Note that converting into one structure is a good idea, as it makes accessing the fields very convenient:
"To explain better what I am trying to do..."
It really doesn't matter to me if you are measuring bubbles or elephant ears: a cell array is a cell array, and a structure is a structure regardless. If you really wanted help you would give information about your data: what sizes it has, exactly the output you need, and you would upload some samples.
