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 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 cortical atrophy ·       Can be 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!
