If a CT study is performed without contrast, how should this be documented?

• A. No documentation is needed about contrast usage.
• B. The report should state that no contrast was used, but no justification is required.
• C. Mention that no contrast was used and briefly justify why; note any limitations.
• D. Do not mention the absence of contrast in the report.

Answer: (C)

When a CT study is performed without contrast, the report should clearly state that no contrast was used, include a brief justification for why contrast was not administered, and note any limitations this creates for interpretation. This transparency helps clinicians understand what findings may be missed or non-typical due to the lack of enhancement, and it guides future imaging decisions (for example, whether a contrast-enhanced exam is needed later). The justification might reference reasons such as renal impairment, contrast allergy, or the clinical question not requiring vascular/contrast-enhanced evaluation. Omitting documentation or the justification risks misinterpretation and uncertainty about the study’s diagnostic adequacy, while noting the absence of contrast without context provides little guidance for follow-up.
