Anyone here had a CT Colonography?

I’m suppose to be getting a CT Colonography next week.

I’m terrified of bowel perforation.

I’ve had all the other necessary tests done and they’ve all come back clear, however I still have bowel dysfunction and Dr says its IBS.

He told me I can/should do a CT Colonoscopy so we can rule out anything else – and for peace of mind.

I still haven’t confirmed appointment and would love to hear honest experiences from those who have had one!

Thank you
