    Area of Science:

    • Orthopedics
    • Radiology
    • Medical Imaging

    Background:

    • Ankle injuries are common and can affect ligaments and cartilage.
    • Accurate imaging is crucial for diagnosis and treatment planning.

    Purpose of the Study:

    • To evaluate the effectiveness of high-field surface coil magnetic resonance (MR) imaging in visualizing ankle structures.
    • To compare MR imaging findings with anatomical dissections and clinical outcomes.

    Main Methods:

    • High-field surface coil MR imaging was performed on 12 ankles (2 healthy volunteers, 7 patients, 3 cadavers).
    • Cadaver ankles were dissected in coronal, sagittal, and axial planes for direct comparison.
    • Patient data included plain film radiography and, in some cases, arthroscopy or surgery.

    Main Results:

    • MR imaging demonstrated excellent delineation of ankle ligaments and cartilaginous structures.
    • Findings were consistent across healthy, patient, and cadaveric specimens.
    • MR imaging provided detailed anatomical information for pathological assessment.

    Conclusions:

    • High-field surface coil MR imaging is a highly effective non-invasive technique for evaluating ankle anatomy.
    • It offers superior visualization of soft tissues like ligaments and cartilage compared to conventional methods.
    • This modality aids in the diagnosis and management of ankle pathologies.
