Table 4.
Intraclass correlation coefficient testing for intra- and interrater reliability of skewness, kurtosis, entropy, and uniformity for T1w and T2w. Results of interrater testing based on analysis of 33 fungal lesions and 38 lymphoma manifestations; results of intrarater testing based on analysis of 9 fungal lesions and 9 lymphoma manifestations. For both intrarater reliability and interrater reliability testing, results of PyRadiomics were considered. ICC, intraclass correlation coefficient
