I can't speak from personal experience on obstructions, but I did get to attend a medical conference on Crohn's earlier this year. And at the conference, one of the presenters talked a bit about how it IS possible for obstructions/strictures to be missed in CT scans, SBFT's, CT enterography, etc. Some of them can be just a few millimeters long (small enough to be missed by radiography) but can significantly close off the bowel.
