Sciatic neuropathy: findings on magnetic resonance neurography
Injuries of the sciatic nerve are common causes of pain and limitation in the lower limbs. Due to its particular anatomy and its long course, the sciatic nerve is often involved in diseases of the pelvis or leg. In recent years, magnetic resonance neurography has become established as an important tool for the study of peripheral nerves and can be widely applied to the study of the sciatic nerv...
متن کاملMR Neurography: Advances
High resolution and high field magnetic resonance neurography (MR neurography, MRN) is shown to have excellent anatomic capability. There have been considerable advances in the technology in the last few years leading to various feasibility studies using different structural and functional imaging approaches in both clinical and research settings. This paper is intended to be a useful seminar f...
متن کاملSomatotopic fascicular organization of the human sciatic nerve demonstrated by MR neurography
OBJECTIVES To investigate whether the human sciatic nerve might have a consistent somatotopic organization according to proximal fascicle input by spinal nerves. METHODS Twelve patients (55.3 ± 15.5 years) with confirmed lesions of either the L5 or S1 spinal nerve root underwent magnetic resonance neurography of sciatic nerve fascicles including thigh and knee levels (T2-weighted sequence wit...
متن کاملMR Neurography - Imaging Peripheral Nerves
MR imaging of peripheral nerves not only allows sensitive detection of peripheral nerve abnormalities but also displays high detail of regional anatomy and improves specificity of diagnosis. The use of MR imaging for diagnosis and evaluation of peripheral nervous system disorders was initially reported in the late 1980’s. Since then, expertise gained through experience over the last decade coup...
متن کاملSciatic Nerve Injury Related to Hip Replacement Surgery: Imaging Detection by MR Neurography Despite Susceptibility Artifacts
Sciatic nerve palsy related to hip replacement surgery (HRS) is among the most common causes of sciatic neuropathies. The sciatic nerve may be injured by various different periprocedural mechanisms. The precise localization and extension of the nerve lesion, the determination of nerve continuity, lesion severity, and fascicular lesion distribution are essential for assessing the potential of sp...
