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.</p></abstract><trans-abstract xml:lang="ru"><p>В работе представлено наблюдение динамики данных магнитно-резонансной томографии (МРТ) и клинической картины пациента, прошедшего лечение тремора верхней конечности путём таламотомии фокусированным ультразвуком (ФУЗ) под контролем МРТ. Пациенту 69 лет с болезнью Паркинсона проведены лечение ФУЗ и контрольные МРТ через 2 и 24 ч, 1, 3, 6 и 12 мес с внутривенным контрастным усилением. Описаны особенности естественного течения очага изменений в головном мозге после процедуры с корреляцией накопления МР-контрастного препарата (МРКС). Показано, что МР-картина характеризуется формированием очага изменённого сигнала в зоне воздействия ФУЗ. Отмечено, что пик накопления МРКС наблюдается через 2 ч и 1 мес после процедуры с выраженным регрессом интенсивности накопления МРКС через 24 ч. ФУЗ продемонстрировал большие перспективы в качестве метода направленного временного нарушения проницаемости ГЭБ, а МРТ головного мозга с контрастным усилением — как критерий оценки степени нарушения проницаемости.</p></trans-abstract><kwd-group xml:lang="en"><kwd>blood-brain barrier</kwd><kwd>focused ultrasound</kwd><kwd>tremor</kwd><kwd>Parkinson’s disease</kwd><kwd>essential tremor</kwd><kwd>magnetic resonance imaging</kwd><kwd>focused ultrasound</kwd><kwd>thalamotomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гематоэнцефалический барьер</kwd><kwd>фокусированный ультразвук</kwd><kwd>тремор</kwd><kwd>болезнь Паркинсона</kwd><kwd>эссенциальный тремор</kwd><kwd>магнитно-резонансная томография</kwd><kwd>фокусированный ультразвук</kwd><kwd>таламотомия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Pardridge WM.
