The term "with contrast" refers to the use of substances that enhance the visibility of specific structures or fluids within the body during medical imaging procedures. When evaluating the methods of administering contrast agents, it's important to understand the contexts in which they are used.

Oral and intravenous methods both involve introducing the contrast agent into the body to assist in imaging procedures. Oral contrast, for example, is typically ingested for imaging of the gastrointestinal tract, helping to delineate structures clearly. Intravenous contrast, on the other hand, is injected directly into the bloodstream, enhancing the visualization of vascular systems and various organs during imaging tests like CT scans or MRIs.

Topical administration is also considered a method of administering contrast in certain contexts, where a contrast agent may be applied directly to the surface of an area being examined, assisting in imaging when superficial layers are of interest.

Rectal contrast, while not as commonly referenced, can also be utilized in specific imaging scenarios, particularly for studies related to the lower gastrointestinal tract.

Given this context, the choice indicating rectal as a method of contrast qualifies it within specific imaging contexts, making it a method of contrast rather than an exclusion.

In summary, the choice that does not fit as a method of contrast is topical
