    Summary
    This summary is machine-generated.

    Air-enhanced computed tomography (CT) effectively visualizes the sellar cisterns and empty sella in patients with iodine allergies. This CT technique offers a viable alternative to traditional contrast agents for detailed anatomical imaging.

    Area of Science:

    • Radiology
    • Neuroimaging

    Background:

    • Iodine contrast agents pose risks for allergic patients.
    • Accurate imaging of the sellar cisterns is crucial for diagnosing pituitary and surrounding structure abnormalities.

    Purpose of the Study:

    • To evaluate the efficacy of air-enhanced computed tomography (CT) for imaging the sellar cisterns.
    • To assess this technique as an alternative for patients with iodine compound allergies.

    Main Methods:

    • Air-enhanced CT of the sellar cisterns was performed on two patients with a history of iodine compound allergy.
    • The technique involved using air as a contrast agent to enhance visualization of the basal cisterns and empty sella.

    Main Results:

    • Both patients demonstrated well-defined basal cisterns and empty sella structures.

  • The air-enhanced CT technique provided clear anatomical details, comparable to conventional methods.

    • Conclusions:

    • Air-enhanced CT is a safe and effective imaging modality for the sellar cisterns in patients with iodine allergies.
    • This technique offers a valuable alternative to iodinated contrast-enhanced imaging, ensuring diagnostic accuracy without allergic risks.
