               Figure 7. Indeterminate renal lesions at CT study. Contrast CT shows in the left kidney voluminous, partially exophitic, hypodense
               lesion with irregular margins and without enhancement in phases arterial (A) and venous phase (B). Greyscale and contrast-enhanced
               sonography (C-D) shows a lesion with mixed echo structure and after microbubble injection shows multiple vascularized septa (Bosniak 4)

               Figure 8. Fusion-guided microwave ablation. 75 years old patient with exophitic in the right kidney, identified by sonography and contrast-
               enhanced ultrasound (A) and confirmed by MR (B), it was a RCC (biopsy proven) treated with microwaves through guided fusion
               technique (C-D). RCC: renal cell carcinoma
