The most common approach is the use of geometric The chief obstacle for such standardization has been the lack of reliable and easy‐to‐use ground‐truth references. However, the generalized use of quantification has been hampered by the lack of the standardization between quantification methods. This has led to the gradual introduction of commercial software for semiquantitative analysis into the clinical routine. Several studies have highlighted the potential benefits of semiquantitative approaches for improving the diagnostic confidence and accuracy in dementia, In particular, 18F‐fluorodeoxyglucose ( 18F‐FDG) PET provides images of the global and regional brain glucose consumption, which are of great interest in the clinical diagnosis and follow‐up of neurological disorders such as epilepsy and different forms of dementia.ĭespite the fact that brain FDG‐PET images are typically interpreted through visual inspection and manual annotation, Positron emission tomography (PET) has been widely used in neurology to study brain metabolism, receptor binding, and alterations in regional blood flow.
