  1. Note. The data show the number of the lesions. The data in the parentheses show the percentage. The heterogeneity of the lesions (homogeneous or heterogeneous) and the percentage of non-enhancing (necrotic) area were evaluated in the predominantly solid ccRCC (n = 192). The presence or absence of calcification was evaluated in total ccRCC cases (n = 214).
