· Leaving the root protocol code makes the study a noncontrast exam | |||
o Adding an “O” – Oral contrast ; Add an “IV” IV Contrast ; add “OIV” for oral AND IV contrast | |||
o Example: BCT 02 is abd/pelv non con; BCT 02IV is abd/pelv cont | |||
· Adding a DE at the end of the original code makes the study a dual energy examination | |||
· Adding a U prior to the IV makes the exam ultralow dose | |||
o BCT 02UIV – abd pelv w/IV contrast, ultralow dose |
