Magnetic resonance-guided focused ultrasound in dystonia: a scoping review

BackgroundMagnetic resonance guided focused ultrasound (MRgFUS) is a non-invasive therapeutic technique that utilizes focused ultrasound waves to generate heat at specific tissue targets within the brain. This emerging technology holds promise for its precision and potential benefits in comparison to traditional surgical interventions. This investigation involves a scoping review, summarizing insights from various studies that explore the advantages, limitations, and outcomes associated with MRgFUS in the treatment of dystonia.MethodsThis scoping review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines. Data available on MRgFUS use in the management of different types of dystonia were extracted.ResultsThere is limited data available (n = 11). In the surveyed literature, MRgFUS has consistently shown clinical benefit in patients with dystonia. It is an emerging avenue of treatment and has its challenges.ConclusionThis scoping review highlighted the early but encouraging applications of MRgFUS in dystonia management. While data was limited, existing studies consistently demonstrated positive clinical outcomes. The non-invasive and precise nature of MRgFUS positions it as a promising avenue for further research, despite the challenges associated with its emergent status. This review sets the stage for future inquiries, emphasizing its potential as a valuable tool in dystonia treatment.
