TUMOUR
Ten randomly selected patients were independently segmented by a second radiologist (JS) and the intra-class correlation coefficient (ICC) was used to reject non-reproducible features with ICC < 0.75. From the 105 computed features, this resulted in the following feature counts for each ROI set: whole tumour = 73, low-enhancing = 48, high-enhancing = 56, tumour core = 72, tumour rim = 58.
