(3)y(i)=x(i)-x¯σwhere y(i) is the normalized feature value of x(i), and σ are the mean and standard deviation of feature x over all patterns of both classes. For the implementation of the classification scheme, the support vector machine (SVM) classifier with linear kernel was...

B Comparison of spleen-to-liver ratios (SUVmaxSpleen/SUVmeanLiver) of patients of all tumor entities included in the study, comparing patients without ongoing (no systemic treatment, n = 85) to those with an ongoing systemic therapy or systemic treatment within the last month prior to ...
Whether through multimodal comparison or hardware-fusion, combining PET and CT appears to add to the value of either modality alone69,70(Figure 2). PET/CT adds to the number of patients with recurrence found over CT alone71and has shown sig...
To the best of our knowledge, this is the first study to investigate the diagnostic value of non-contrast 18F-FDG PET/MRI, which has the diagnostic performance of both PET and MRI, for the staging of endometrial cancer in comparison with conventional imaging modalities such as ceMRI and ceCT...
The prognostic value was externally validated when using a pre-specified cutoff value. This is a remarkable finding since patients´ characteristics and treatment between participating centers differed considerably. However the prognostic value for the calculated signature could not be validated by non-...
This individual variability in responsiveness to SSRI intervention diminishes the sensitivity of a simple intervention group comparison and reinforces the value of modeling interindividual differences in change in central serotonin levels. Although the extent to which our observed effects in a healthy ...
The log-rank test comparison between the Kaplan–Meier curves, where patients were stratified according to the median value, exhibited a p-value smaller than 0.05. This indicates the ability of the radiomic feature Major Axis Length to stratify patients in different risk classes, connected to a ...
18F-fluorodeoxyglucose (18F-FDG) PET to enable comparison. The rabbit cohorts had similar PET signal distributions (Fig. 4f). When aortic segments were studied,18F-FDG and18F-nanoparticle signal correlated with anR2=0.518 (P<0.0001, Pearson correlation coefficient,Fig. 4g). The difference in ...
