🧠 FDG PET/CT in Alzheimer’s Disease

Fluorodeoxyglucose (FDG) PET remains one of the most valuable tools for assessing neuronal function and regional cerebral metabolism in neurodegenerative disorders.

🧩 Characteristic pattern:
🔹 Bilateral, symmetrical hypometabolism in posterior cingulate, precuneus, and parietotemporal cortices
🔹 Relative sparing of the sensorimotor cortex, visual cortex, and often the basal ganglia & cerebellum
🔹 As disease advances, frontal lobes may also become involved

📉 These metabolic changes often precede structural atrophy — helping in early diagnosis and differentiation from other dementias (like frontotemporal or Lewy body dementia).

🧬 FDG-PET bridges the gap between anatomy and function — a window into the brain’s metabolic map.

🔥💡Normal Distribution of F-18 Sodium Fluoride PET ✨💀

🦴 F-18 NaF PET highlights bone turnover, not just anatomy!

🔹 Physiologic uptake:
✅ Joints & growth plates
✅ Spine, pelvis, ribs & sternum
✅ Mandible & skull base
💧 Kidneys & bladder (due to renal excretion)

🚫 No significant soft-tissue uptake — that’s your key to spot pathology 🔍

🎯 Know normal before you call abnormal!
