abstract = {Diagnostic criteria for progressive supranuclear palsy
(PSP) include midbrain atrophy in MRI and hypometabolism in
[18F]fluorodeoxyglucose (FDG)-positron emission tomography
(PET) as supportive features. Due to limited data regarding
their relative and sequential value, there is no
recommendation for an algorithm to combine both modalities
to increase diagnostic accuracy. This study evaluated the
added value of sequential imaging using state-of-the-art
methods to analyse the images regarding PSP features.The
retrospective study included 41 PSP patients, 21 with
Richardson's syndrome (PSP-RS), 20 with variant PSP
phenotypes (vPSP) and 46 sex- and age-matched healthy
controls. A pretrained support vector machine (SVM) for the
classification of atrophy profiles from automatic MRI
volumetry was used to analyse T1w-MRI (output: MRI-SVM-PSP
score). Covariance pattern analysis was applied to compute
the expression of a predefined PSP-related pattern in
FDG-PET (output: PET-PSPRP expression score).The area under
the receiver operating characteristic curve for the
detection of PSP did not differ between MRI-SVM-PSP and
PET-PSPRP expression score (p≥0.63): about 0.90, 0.95 and
0.85 for detection of all PSP, PSP-RS and vPSP. The
MRI-SVM-PSP score achieved about $13\%$ higher specificity
and about $15\%$ lower sensitivity than the PET-PSPRP
expression score. Decision tree models selected the
MRI-SVM-PSP score for the first branching and the PET-PSPRP
expression score for a second split of the subgroup with
normal MRI-SVM-PSP score, both in the whole sample and when
restricted to PSP-RS or vPSP.FDG-PET provides added value
for PSP-suspected patients with normal/inconclusive T1w-MRI,
regardless of PSP phenotype and the methods to analyse the
images for PSP-typical features.},
