Recent advances in imaging techniques of renal masses

Figure 5 Pre-treatment (A) and post-treatment (B) computed tomography perfusion images in a case of large left renal cell carcinoma with metastasis to the uncinate process of the pancreas (yellow arrow). Comparison of perfusion parameters at the 6-mo follow-up after anti-angiogenic therapy showed that there was an increase in BF and BV, which was suggestive of progressive disease. No significant change in lesion size would have qualified this case as a stable disease as per size criteria.
