Four contrast-enhanced CT images of different pathological renal tumors. The tumors are marked by yellow arrows in 3D views. The manual contours of the renal tumors delineated by a radiologist are displayed in 2D slices. The pathological subtypes of the renal tumors are clear cell renal cell carcinoma (RCC) in (a) and (b), chromophobe RCC in (c) and angiomyolipoma in (d)
