Meralgia paresthetica is a neuropathy of the lateral femoral cutaneous nerve. Traditionally, the diagnosis is based on classical symptoms and signs. In cases where there is a diagnostic dilemma, the role of magnetic resonance imaging has been to exclude other causes for the patient's presentation, as the small extraspinal peripheral nerves were not well visualised at imaging. The development of 3-Tesla magnetic resonance neurography, however, has made pathology of these nerves more conspicuous.
股外侧皮神经感觉异常是一种股外侧皮神经的神经病变。传统上，诊断基于典型的症状和体征。在存在诊断困境的病例中，磁共振成像的作用一直是排除导致患者症状的其他原因，因为在成像中无法很好地显示椎管外的小周围神经。然而，3特斯拉磁共振神经造影的发展使这些神经的病变更加明显。
