Multimodal MRI for MRgFUS Central Lateral Thalamotomy in Neuropathic Pain
China12 participantsStarted 2021-12-01
Plain-language summary
To explore the pathogenesis underlying neuropathic pain as well as the mechanisms of pain relief after Magnetic resonance-guided focused ultrasound (MRgFUS) Central Lateral Thalamotomy through multi-model MRI study, and to identify imaging biomarkers for triaging patients and predicting the clinical outcomes. Craniofacial neuropathic pain is one of the most serious debilitating symptoms, leading to emotional disorders and poor quality of life. Previous studies have shown that Magnetic resonance-guided focused ultrasound (MRgFUS) central lateral thalamotomy is a minimally invasive and effective procedure for medication-refractory neuropathic pain patients. However, the clinical benefits were variable among individuals. It is important to clarify the pathogenesis of neuropathic pain and the mechanisms of pain relief induced by MRgFUS central lateral thalamotomy to triage suitable candidates for the procedure and predict clinical outcomes. In addition, localization precision and individualized treatment remain to be improved.
