Fig. 1From: Preoperative lipiodol marking and its role on survival and complication rates of CT-guided cryoablation for small renal massesA case of cryoablation with preoperative lipiodol marking. The red circle indicates the primary tumor. a The right renal tumor was detected by a preoperative dynamic computed tomography (CT) scan. b The tumor was easily detected by intraoperative plain CT after lipiodol marking. c A postoperative CT scan showed no enhancement in the cryoablated area. A complete response was achieved by cryoablation according to the mRECIST criteriaBack to article page
