What does it mean an abdominal ct scan and pelvic ct scan with contrast? is that iv or do i have to drink something?

It could be either type.of contrast depending upon what your MD is looking for. Oral contrast with barium is useful to outline stomach and intestines. Iv contrast is used in most other cases. I think the radiology department will answer your question best,though.

It involves being given something IV. Sometimes if for GI reasons you may be given oral contrast
