Abstract
The study presents an observation of magnetic resonance imaging (MRI) data changes and clinical manifestations in a patient who underwent MRI-guided focused ultrasound (FUS) thalamotomy for upper limb tremor treatment. A 69-year-old patient with Parkinson’s disease received FUS treatment, followed by contrast-enhanced MRI scans at 2 hours, 24 hours, 1 month, 3 months, 6 months, and 12 months post-procedure. The paper describes natural progression patterns of brain lesion changes after the intervention with correlation to MR contrast agent (MRCA) accumulation. MRI findings revealed an altered signal intensity area in the FUS target area. Peak MRCA accumulation was observed at 2 hours and 1 month post-procedure, with marked regression of contrast enhancement intensity by 24 hours. FUS demonstrated significant potential as a method for targeted temporary blood-brain barrier permeability disruption, while contrast-enhanced brain MRI proved valuable for assessing permeability alteration severity.
