Assessment of glucose metabolism in the BF by FDG PET is hampered by the small size of the BF and limited spatial resolution of conventional PET. This pilot study tested the feasibility of assessing BF glucose metabolism by high-resolution digital PET (dPET).Patients and Methods The retrospective study included 12 LBS patients (61–86 years, 5 demented). Whole-brain stereotactic normalization to anatomical standard space was followed by local stereotactic normalization of a 7 × 7 × 7-cm3 box around the BF to a custom-made 1 × 1 × 1-mm3 FDG dPET template. FDG uptake was scaled voxelwise to mean FDG uptake in the pons. Scaled FDG uptake in the BF was compared between demented and nondemented LBS patients and tested for correlation with cortical FDG uptake.Results Scaled FDG uptake in the BF was significantly lower in demented compared with nondemented patients (1.14 ± 0.09 vs 1.25 ± 0.06, P = 0.031). Brain-wide voxel-based testing for correlations with scaled FDG uptake in the BF revealed a large cluster comprising medial and ventrolateral frontal cortex, anterior cingulate cortex, insular cortex, and striatum as well as smaller clusters in motor cortex and occipital cortex (P < 0.001, uncorrected).Conclusions These results suggest that dementia-associated BF degeneration in LBS can be sensitively measured as reduced BF FDG uptake on dPET. More accurate delineation of the BF based on individual high-resolution MRI might be useful to make optimal use of improved spatial resolution of dPET and to correct for possible disease- and age-dependent partial volume effects. 000151491 536__ $$0G:(DE-HGF)POF3-344$$a344 - Clinical and Health Care Research (POF3-344)$$cPOF3-344$$fPOF III$$x0 000151491 536__ $$0G:(DE-HGF)POF3-345$$a345 - Population Studies and Genetics (POF3-345)$$cPOF3-345$$fPOF III$$x1 000151491 588__ $$aDataset connected to CrossRef 000151491 7001_ $$aFrings, Lars$$b1 000151491 7001_ $$aApostolova, Ivayla$$b2 000151491 7001_ $$0P:(DE-HGF)0$$aLange, Catharina$$b3 000151491 7001_ $$aKlutmann, Susanne$$b4 000151491 7001_ $$aAdam, Gerhard$$b5 000151491 7001_ $$aBannas, Peter$$b6 000151491 7001_ $$aMeyer, Philipp T.$$b7 000151491 7001_ $$0P:(DE-2719)2810708$$aGrothe, Michel J.$$b8$$udzne 000151491 7001_ $$aBuchert, Ralph$$b9 000151491 77318 $$2Crossref$$3journal-article$$a10.1097/rlu.0000000000002960$$b : Ovid Technologies (Wolters Kluwer Health), 2020-04-01$$n4$$p261-266$$tClinical Nuclear Medicine$$v45$$x0363-9762$$y2020 000151491 773__ $$0PERI:(DE-600)2045053-9$$a10.1097/RLU.0000000000002960$$gVol. 45, no. 4, p. 261 - 266$$n4$$p261-266$$tClinical nuclear medicine$$v45$$x0363-9762$$y2020 000151491 909CO $$ooai:pub.dzne.de:151491$$pVDB 000151491 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2810708$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b8$$kDZNE 000151491 9131_ $$0G:(DE-HGF)POF3-344$$1G:(DE-HGF)POF3-340$$2G:(DE-HGF)POF3-300$$aDE-HGF$$bForschungsbereich Gesundheit$$lErkrankungen des Nervensystems$$vClinical and Health Care Research$$x0 000151491 9131_ $$0G:(DE-HGF)POF3-345$$1G:(DE-HGF)POF3-340$$2G:(DE-HGF)POF3-300$$aDE-HGF$$bForschungsbereich Gesundheit$$lErkrankungen des Nervensystems$$vPopulation Studies and Genetics$$x1 000151491 9141_ $$y2020 000151491 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2020-01-02 000151491 915__ $$0StatID:(DE-HGF)0410$$2StatID$$aAllianz-Lizenz$$d2022-11-29$$wger 000151491 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bCLIN NUCL MED : 2021$$d2022-11-29 000151491 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2022-11-29 000151491 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2022-11-29 000151491 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2022-11-29 000151491 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2022-11-29 000151491 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2022-11-29 000151491 915__ $$0StatID:(DE-HGF)9910$$2StatID$$aIF >= 10$$bCLIN NUCL MED : 2021$$d2022-11-29 000151491 9201_ $$0I:(DE-2719)7000008$$kU T4 Researchers - Bonn$$lU T4 Researchers - Bonn$$x0 000151491 9201_ $$0I:(DE-2719)1510100$$kClinical Dementia Research Rostock /Greifswald ; AG Teipel$$lClinical Dementia Research Rostock /Greifswald$$x1 000151491 980__ $$ajournal 000151491 980__ $$aVDB 000151491 980__ $$aI:(DE-2719)7000008 000151491 980__ $$aI:(DE-2719)1510100 000151491 980__ $$aUNRESTRICTED
