abstract = {According to the World Health Organization classification
for tumors of the central nervous system, mutation status of
the isocitrate dehydrogenase (IDH) genes has become a major
diagnostic discriminator for gliomas. Therefore,
imaging-based prediction of IDH mutation status is of high
interest for individual patient management. We compared and
evaluated the diagnostic value of radiomics derived from
dual positron emission tomography (PET) and magnetic
resonance imaging (MRI) data to predict the IDH mutation
status non-invasively.Eighty-seven glioma patients at
initial diagnosis who underwent PET targeting the
translocator protein (TSPO) using [18F]GE-180, dynamic amino
acid PET using [18F]FET, and T1-/T2-weighted MRI scans were
examined. In addition to calculating tumor-to-background
ratio (TBR) images for all modalities, parametric images
quantifying dynamic [18F]FET PET information were generated.
Radiomic features were extracted from TBR and parametric
images. The area under the receiver operating characteristic
curve (AUC) was employed to assess the performance of
logistic regression (LR) classifiers. To report robust
estimates, nested cross-validation with five folds and 50
repeats was applied.TBRGE-180 features extracted from
TSPO-positive volumes had the highest predictive power among
TBR images (AUC 0.88, with age as co-factor 0.94). Dynamic
[18F]FET PET reached a similarly high performance (0.94,
with age 0.96). The highest LR coefficients in multimodal
analyses included TBRGE-180 features, parameters from
kinetic and early static [18F]FET PET images, age, and the
features from TBRT2 images such as the kurtosis (0.97).The
findings suggest that incorporating TBRGE-180 features along
with kinetic information from dynamic [18F]FET PET, kurtosis
from TBRT2, and age can yield very high predictability of
IDH mutation status, thus potentially improving early
patient management.},
