In particular, 11 studies have been conducted to develop and evaluate MRI-based radiomics for the differentiation of grade in STS tumours [20, 25, 32, 35–43]; furthermore, a study among these aforementioned ones aimed to predict the grade and the Ki-67 expression level by utilising intravoxel incoherent motion MRI and diffusion kurtosis imaging parameter maps [43]. The gene discussed is MKI67; the disease is neoplasm.
