Demansta Nükleer Tıp Görüntülemelerinde Yenilikler

Öz:
Alzheimer hastalığı (AH) ve diğer dejeneratif demansların moleküler biyolojisi, patolojisi ve genetiği ile ilgili gelişmeler, bu hastalıklara özgü biyobelirteçlerin ve nükleer tıp alanında radyo-işaretleyicilerin gelişmesini sağlamıştır. Görüntüleme ve görüntüleme dışı belirteçler bu hastalıkların çok erken tanınmalarını sağlayarak tanımlanmalarında da önemli değişikliklere neden olmuşlardır. Moleküler görüntüleme yöntemlerinden olan amiloid pozitron emisyon tomografisi (PET) ve tau PET, beyindeki glukoz metabolizma paternini gösteren florodeoksiglukoz (FDG) PET, dopaminerjik terminalleri işaretleyen dopamin taşıyıcı tek foton emisyon tomografisi (SPECT), AH’nı ve atipik varyantlarını, frontotemporal demansları ve Lewy cisimcikli demansı erken tanıma ve birbirlerinden ayırt etmede değerli araçlardır. Birbirlerine göre farklı üstünlükleri olan bu görüntüleme yöntemlerinin kullanım endikasyonları farklıdır ve kimi zaman birbirlerini tamamlayan bilgi verirler. Ayrıca, nöroenflamasyonu, astrositleri, sinaptik yoğunluğu ve kolinerjik terminalleri hedefleyen radyoişaretleyiciler ile araştırmalar devam etmektedir. Bu derlemede, AH ve diğer nörodejeneratif demanslarda rutin olarak kullanılan ya da yeni geliştirilen nükleer görüntüleme yöntemleri, kullanılan ajanlar ve tanısal özellikleri, olgu örnekleri ile beraber sunulacaktır.

What is New in Nuclear Medicine Imaging for Dementia

Öz:
Advances in the molecular biology, pathology and genetics of Alzheimer’s disease (AD) and other degenerative dementias have led to the development of biomarkers specific to these diseases and radiotracers that are used in nuclear medicine. Imaging and nonimaging markers have enabled very early recognition of these diseases and have caused significant changes in their definitions. Amyloid positron emission tomography (PET) and tau PET, which are molecular imaging methods, [F18]fluorodeoxyglucose (FDG) PET showing the glucose metabolism pattern in the brain, dopamine transporter single photon emission computerized tomography (SPECT) that marks dopaminergic terminals are valuable tools for early recognition and differentiation of AD and its atypical variants, frontotemporal dementias and dementia with Lewy bodies. These imaging methods, which have different advantages over each other, have different indications for use and provide complementary information. In addition, research on radiotracers targeting neuroinflammation, astrocytes, synaptic density, and cholinergic terminals is ongoing. In this review, routinely used and newly developed nuclear imaging methods in AD and other neurodegenerative dementias, the agents used and their diagnostic features will be presented together with case examples.
