F-18-FDG PET brain imaging is commonly used in the early detection and differential diagnosis of various subtypes of dementias.F- 18-FDG PET images are mainly evaluated visually, and semiquantitative analysis programs are also commonly used in many centers. However, visual and semiquantitative analysis carry certain limitations. Visual assessment is subjective and dependent on expertise. Commercially available semiquantitative analysis programs have certain limitations such as suboptimal selection of brain areas or erroneous uptake normalization procedures that may provide inaccurate results, and physicians reporting semiquantitative results should be aware of these. In this pictorial review article, we will discuss the current status of F-18-FDG PET brain imaging in patients with dementia and present figures and semiquantitative analysis results of various sub-types of dementias as well as certain artifacts seen on F-18-FDG PET brain imaging studies.
