    Area of Science:

    • Neuroanatomy
    • Radiology
    • Medical Imaging

    Background:

    • The medulla oblongata's complex anatomy presents challenges for imaging.
    • Accurate identification of medullary structures is crucial for diagnosing neurological conditions.

    Purpose of the Study:

    • To correlate computed tomographic (CT) anatomy of the medulla with cadaveric dissections.
    • To establish optimal CT parameters for medullary evaluation.

    Main Methods:

    • Studied the medulla in cadavers and 100 patients.
    • Utilized computed tomography (CT) with and without intrathecal contrast administration.
    • Correlated CT images with anatomic dissections.

    Main Results:

    • Identified characteristic contours of pyramids, olives, and inferior cerebellar peduncles on CT.
    • Differentiated the hypoglossal nerve from other cranial nerves based on location and course.
    • Demonstrated the utility of intrathecal contrast for improved visualization.

    Conclusions:

    • CT provides reliable visualization of medullary anatomy.
    • Intrathecal contrast administration enhances medullary structure delineation.
    • Recommended specific CT slice thickness and orientation for optimal medullary evaluation.
