That is true, but I had 3 CTs and 3 MRIs. Out of the six tests, 2 said remnants (the very first and the last) and four measured something that was 2.5 cm to 5.7 cm.

What I know about CT scans is to think of a moving tire with a nail in it. The CT scan may get the shot of the nail or it might miss out on that image.
