    Magnetic Resonance Imaging (MRI) offers superior visualization for certain lesions compared to computed tomography (CT). The Patil System enables MRI stereotaxis, overcoming reference marker challenges in strong magnetic fields.

    Area of Science:

    • Medical imaging
    • Neurosurgery
    • Biomedical engineering

    Background:

    • Computed tomography (CT) scans have limitations in visualizing certain lesions.
    • Magnetic Resonance Imaging (MRI) provides better definition for specific pathologies.
    • Accurate localization of lesions is crucial for stereotactic procedures.

    Purpose of the Study:

    • To describe the technique of MRI stereotaxis using the Patil System.
    • To demonstrate the utility of MRI for lesion visualization.
    • To address challenges in reference marker visibility during MRI.

    Main Methods:

    • Utilizing the Patil System, designed for use in strong magnetic fields.
    • Employing methods to overcome reference marker visualization issues (mineral oil coating, paramagnetic fluid rods).
