    Trigeminal neuralgia (TN) includes classical, secondary, and idiopathic types, with classical TN being the most common due to neurovascular compression.

  • 2

    MRI is crucial for evaluating classical TN, enabling visualization of neurovascular contact and nerve distortion through advanced imaging techniques.

  • 3

    There is no consensus on the optimal MRI parameters for diagnosing TN, leading to variability in imaging protocols and study designs.

  • 4

    This systematic review aims to clarify the diagnostic utility of MRI in TN and identify areas needing further standardization and research.

  • 5

    High-resolution 3D T2-weighted MRI sequences are most effective for detecting neurovascular conflicts in classical TN, especially when combined.
