Have some mild cognitive impairment trying to remember dementia patterns on imaging?
Is looking at dementia PET scans one of your PET peeves?
Have short-term memory loss when you read about dementia imaging?
Here’s a way to remember dementia patterns so you will never forget!
Major dementia imaging patterns:
➡️Alzheimer’s disease (AD)
🔸AD has a Nike swoosh pattern—with decreased metabolism in the parietal & temporal regions
🔸Remember when you see the Nike swoosh patter, just call it!
➡️Dementia w/Lewy Bodies (DLB)
🔸Temporoparietal hypometabolism like AD but also involves occipital cortex, specific for DLB. DLB also extends farther to the ant. temporal cortex.
🔸Remember, regions of hypometabolism look more like an L. And Lewy starts w/an L
➡️Frontotemporal Dementia (FTD)
🔸Frontal & temporal hypometabolism as expected, but extends along the anterior cingulate gyrus
🔸Anterior cingulate involvement makes the hypometabolism looks like a lowercase letter f—and frontotemporal starts with f
➡️Posterior cerebral atrophy
🔸Can from AD or DLB & has hypometabolism in the occipital & post. temporal lobe, sparing the anterior temporal lobe
🔸Sparing the anterior temporal lobe makes the involvement look like a C instead of an L like DLB.
So remember pCa
➡️Vascular dementia
🔸Vascular dementia has a variable distribution, depending on the regions infarcted (V is both for Vascular & Variable)
🔸Wedged shaped regions of hypometabolism corresponding to cortical infarcts—looks like an inverted V
This list isn’t all inclusive & there can be variations or even mixed dementias
But hopefully this gives you a starting point you won’t soon forget!
