    Summary

    A new corn oil emulsion (COE) provides effective gastrointestinal (GI) tract visualization for abdominal CT scans. This oral contrast agent offers comparable diagnostic quality to conventional agents with good patient tolerance.

    Area of Science:

    • Radiology
    • Gastroenterology
    • Medical Imaging

    Background:

    • Inadequate mixing of gastrointestinal (GI) contents with oral contrast agents can compromise abdominal CT scan quality.
    • Conventional high-density agents may present challenges in achieving optimal contrast distribution.

    Purpose of the Study:

    • To evaluate the efficacy and tolerability of a flavored 12.5% corn oil emulsion (COE) as an oral contrast agent for abdominal CT.
    • To compare the diagnostic performance of COE with conventional high-density oral contrast agents.

    Main Methods:

    • A prospective study involving 62 patients administered flavored 12.5% corn oil emulsion (COE).
    • Comparative analysis with 105 patients who received standard high-density oral contrast agents.
    • Development of a simple patient preparation regimen for COE.

    Main Results:

    • COE demonstrated consistent discrimination of the GI tract and clear depiction of the GI wall.
    • Diagnostic studies using COE were comparable to those achieved with conventional agents.
    • The COE preparation regimen was well-tolerated by patients.

    Conclusions:

    • Flavored 12.5% corn oil emulsion (COE) is a viable and effective oral contrast agent for abdominal CT.
    • COE offers diagnostic quality comparable to traditional agents with potential benefits in specific patient groups.
    • COE may be particularly advantageous for evaluating the stomach, duodenum, pancreas, suspected solid tumors, and in thin individuals.
