Contrast Enhanced Ultrasound of the Kidneys: What Is It Capable of?
Figure 1
Renal cell carcinoma: a large mixed echogenicity lesion is seen in the middle of the left kidney on B-mode US (a). Colour Doppler (b) reveals some peripheral blood flow. On CEUS (c) there is uptake inside the lesion, but altogether different enhancement than the rest of the kidney. Contrast enhanced CT (d) confirms the mass. Histology after surgery diagnosed a renal cell carcinoma.
