Trigeminal nerve - artery contact in people without trigeminal neuralgia - MR study.

Background: Neurovascular conflict is regarded as the most common cause of idiopathic trigeminal neuralgia. It is suspected that a blood vessel in contact with the root entry zone of a trigeminal nerve causes its irritation. The aim of the study was to evaluate how signs of neurovascular conflict can be found in people without trigeminal neuralgia

Material/methods: The study was conducted retrospectively.
