Note. The data show the number of the lesions. 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).
*Calcification is significantly more common in grades 3–4 than grades 1–2. †Non-enhancing area 60% or more within the predominantly solid clear cell renal cell carcinoma is significantly more common in grades 3–4 than grades 1–2.
