for k = 1:22
pic2read = strcat(num2str(k),'.dcm');
if k<10
pic2read = strcat('0',pic2read);
end
imread(pic2read);
end

use the save option.
doc save
will tell you all the saving option available.
It will be something like:
save('my_data_file.mat','your_images_array')

Adding the '0' manually is a really inefficient solution. See Andrei's much nicer and faster sprintf method.

+1. This is compact, direct, fast, not prone to typos.
