What is contrast? What if I am allergic to the contrast?
Contrast can be used either intravenously (injection) and/or gastrointestinal (by mouth) to make anatomical structures enhance differently. The enhancement helps to radiologist distinguish organs and better define different types of pathology. Fort Sanders West Diagnostic Center uses non-ionic intravenous contrast for all CT and x-ray procedures. Non-ionic contrast, in general, has fewer reactions.
