Everything you need to know about Computed Tomography (CT) & CT Scanning


Introduction

question1. What are the common contrast agents used in Body CT Scanning?
question2. Why do we routinely use oral and IV contrast for CT scanning?
question3. Do we always use IV and oral contrast in “every” patient?
questionFor select applications we may use oral contrast only, IV contrast only or no contrast at all. Two examples where no contrast is used is for high resolution chest CT where we are looking for lung infiltrates, and renal stone studies where we are looking for renal calculi.
question4. Who decides on the use of oral and IV contrast in a specific patient?
