Abstract:
This article presents a comprehensive review of MR imaging findings of the sciatic nerve from the pelvis to the knee, highlighting key clinical and diagnostic features of various compressive, neoplastic, and traumatic pathology. Magnetic resonance neurography (MRN) provides an advanced, noninvasive modality for evaluating the nerve anatomy, and its relationship with surrounding structures, enabling precise diagnosis and treatment planning. While high-resolution conventional 2-dimensional sequences such as T1-weighted and T2-weighted fast-spine echo form the backbone of MRN protocols, other 3-dimensional and functional MR imaging techniques can play an important role in facilitating presurgical planning and enhancing more complete tumor characterization.
