Fig. 1From: Lipiodol retention pattern assessed by cone beam computed tomography during conventional transarterial chemoembolization of hepatocellular carcinoma: accuracy and correlation with responseA 52-year-old male with multiple HCCs. a Preprocedure arterial phase contrast-enhanced CT shows index tumors in segments II and VII (arrows); b CBCT immediately after TACE showed these two tumor with complete lipiodol retention pattern concordance with CE-CT (arrows); c On the fluoroscopy image, complete lipiodol retention pattern is well shown on the large tumor in segment VII, but no retention in the small tumor in segment II. d Postprocedure 1Â month follow-up contrast-enhancement CT shows both tumors without contrast enhancement (arrows) representing complete responseBack to article page
