Возможности ядерной медицины в диагностике деменций

Возможности ядерной медицины в диагностике деменций

Abstract

В работе представлено мнение о применимости различных методов ядерной медицины для диагностики, в том числе дифференциальной, различных деменций. Перфузионная однофотонная эмиссионная компьютерная томография с эксаметазимом и позитронно-эмиссионная томография с 13F-фтордезоксиглюкозой высокочувствительны и высокоспецифичны и рекомендуются для широкого применения в клинической практике. Эффективность визуализации распределения амилоида при выявлении болезни Альцгеймера остается под сомнением, так как накопление амилоида характерно для пациентов с другими деменциями. Визуализация распределения переносчиков дофамина с 123I-иофлупаном крайне эффективна в диагностике болезни Паркинсона и деменции с тельцами Леви: ее результаты могут обусловливать коррекцию тактики лечения. Дальнейшее развитие методов, скорее всего, будет заключаться в разработке новых радионуклидных маркеров к таким мишеням, как клетки микроглии и нейрофибриллярные клубки.

In this work the authors share their opinion on the role of nuclear medicine imaging in the diagnosis and differential diagnosis of dementias. Perfusion single-photon emission computed tomography using "mTc-exametazim and 18F-fluorodeoxyglucose positron emission tomography are highly sensitive and specific; they are recommended for a wide range of clinical applications. The efficacy of amyloid imaging in Alzheimer’s is still a matter of discussion, because amyloid accumulation is also typical in patients with other dementias. Dopamine transporter imaging using 123l-ioflupane is a very reliable diagnostic tool for Parkinson’s disease and Lewy body dementia, and can help to adjust treatment strategies. Further evolution of nuclear medicine methods will most likely include the development of new radionuclide tracers for such targets as microglial cells' activation and neurofibrillary tangles.
