“…Hu et al, in 2015 used multi-parametric MRI and texture analysis to predict tumour density in both enhanced and non-enhanced part based on a biopsy study and showed 85% accuracy in training set and 81.8% accuracy in the validation 12 . Further study conducted by Kim et al, showed that the FA and the CBV radiomics of the peritumoural area, together with the clinical index, can potentially predict the tumour progression 13 .…”

“…In summary, high CBV values of nonenhancing T2 hyperintense lesions seemed to be the most useful parameter for LR prediction. Kim et al also reported that CBV features from nonenhancing regions were useful for anticipating local recurrence, and even more signi cant if combined with franctional anisotrpy 20 . Our LR prediction model results determined that in the CBV maps, nonenhancing area were more competent than contrast-enhanced regions.…”

“…Though we reduced the over tting due to high-dimensionality by using dimension reduction, and data augmentation, the prediction model should be further improved using a larger dataset. In addition, radiomics data may be dependent on MR scanner or sequence settings, which was equalized in this study 20 . Further research with multicentered larger sample size with prospective design should be conducted to validate the generalizability of the developed model.…”

“…Other studies have similarly showed that CBV features, associated with tumor aggressiveness, is valuable parameters for prediction of glioma patient survival and prognosis 17 – 19 . However, single parameter approach has been noted for limited ability in survival prediction 20 , 21 . Recently, radiomics approach, in combined with building prediction models with large number of parameters such as neural networks has enabled accurate prediction at an individual level 8 , 22 , though the developed models should be sufficiently validated.…”
