"EAR" artifact in brain scans.

D D Patton, D L Brasfield

    Journal of Nuclear Medicine : Official Publication, Society of Nuclear Medicine
    |April 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    High-resolution brain imaging may show ear artifacts anterior to the lateral sinus. Taping the auricle down typically resolves this artifact, which may worsen with improved imaging resolution.

    Area of Science:

    • Radiology
    • Medical Imaging
    • Neuroimaging

    Background:

    • High-resolution imaging techniques are crucial for detailed anatomical visualization.
    • Artifacts can obscure or mimic anatomical structures in medical imaging.
    • The lateral view of the brain is essential for diagnosing various neurological conditions.

    Purpose of the Study:

    • To identify and describe a common artifact in high-resolution lateral brain imaging.
    • To propose a simple method for artifact mitigation.

    Main Methods:

    • Utilizing high-resolution lateral imaging views of the brain.
    • Observing anatomical structures and imaging artifacts.
    • Implementing a technique to reduce the artifact.

    Main Results:

    • The ear closest to the camera can appear as a structure anterior to the lateral sinus.
    • Taping the auricle down effectively eliminates this imaging artifact.
    • This artifact is likely to become more prevalent with advancements in image resolution.

    Conclusions:

    • The auricle can cause a significant artifact in high-resolution lateral brain imaging.
    • A simple maneuver (taping the auricle) can resolve this artifact.
    • Radiologists should be aware of this artifact, especially with evolving imaging technology.
