Intense accumulation of the radiotracer in the left medial, inferior and superior lobe
The findings are consistent with herpes simplex encephalitis |
Herpes Simplex Encephalitis
|
|
|
Reduced perfusion ot the temporal and inferior parietal cortex bilaterally
Siymmetric uptake in the basal ganglia and thalami |
Alzheimer's Disease
|
|
|
Large left frontal and temporal lobe perfusion defect extending to and involving the basal ganglia
Decreased perfusion to the right cerebellar hemisphere Large left middle cerebral artery stroke with crossed cerebellar diaschisis |
Alzheimer's Dementia (Pick's Disease Dementia)
|
|
|
Global reduction in cerbral perfusion with high background activity
Multiple scattered perfusion defects involving the temporal cortex in both hemispheres and the inferior parietal and superior parietal cortex on the left |
Cocain abuse (continued abuse)
|
|
|
Perfusion defects involving the lateral temporal and parietal cortex bilaterally, and the left medial temporal cortex
Symmetrical tracer uptake in both thalami and basal ganglia Increased background activity |
Cocaine abuse (abstinences)
|
|
|
Large left frontal and temporal lobe perfusion defect extending to and involving the basal ganglia
decreased perfusion to the right cerebellar hemisphere Large left middle cerbral artery stroke with crossed cerebellar diaschisis |
Stroke (crossed cerebellar diaschisis)
|
|
|
dramatic increase in perfusion following acute ischemic phase at the site of the stroke
|
Stroke Luxury Perfusion
|
|
|
multiple perfusion defects involving the temporal lobes
left frontal hyperemic focus probably due to luxury perfusion |
Lyme Disease

|
|
MRI: changes secondary to radiation treatment. Signal enhancement in the region of the tumor bed is suspicious for tumor recurrence
Thallium SPECT: Intense focus of thallium uptake in deep right temporal lobe Tc-99m HMPAO SPECT Hyperemia corresponding TI-201 uptake in temporal lobe. htere is a second focus of hyperemia in the left anterior temporal cortex without corresponding TI-201 uptake |
